Description

Single board, network device and management method

This disclosure claims priority to Chinese patent application No. 202310851009.2 filed on July 11, 2023, with invention name “Single Board, Network Equipment and Management Method”, the entire contents of which are incorporated by reference in this disclosure.

Technical Field

The present disclosure relates to the field of communication technology, and in particular to a single board, a network device, and a management method.

Background Art

The network device has a single board, for example, a main control switch board, which has a service processing module and a management module. The service processing module is used for service processing, and the management module is used for managing the service processing module.

When the management module of a board fails or needs to be upgraded, the board needs to be unplugged. However, this will make the service processing module of the board unable to work, resulting in a decrease in the service processing capacity of the network device.

Summary of the invention

The present disclosure provides a single board, a network device, and a management method. The single board includes a base board and a daughter board. The base board has a service processing module, and the daughter board has a management module. The daughter board and the base board are pluggable. When the daughter board is unplugged, the service processing module of the base board can still perform service processing, so that the service processing capacity of the network device remains unchanged. The technical solutions of the single board, the network device, and the management method are as follows:

In a first aspect, the present disclosure provides a single board. The single board includes a baseboard and a subboard, the subboard is pluggable and connected to the baseboard, and the panel of the baseboard has an opening for plugging and unplugging the subboard. The baseboard has a service processing module, and the subboard has a management module, and the management module is used to manage the service processing module.

The single board can be a main control switch board. The baseboard occupies a slot of the network device. The daughterboard can be plugged in and out of the baseboard, and the daughterboard does not occupy a slot of the network device alone. When the daughterboard is inserted into the baseboard, the management module of the daughterboard is electrically connected to the service processing module of the baseboard. The management module of the daughterboard is used to implement the operations required by the control plane.

The technical solution provided by the present disclosure is to set the service processing module on the base plate, set the management module on the sub-board, and set the sub-board and the base plate to be pluggable, so that when the management module fails or needs to be upgraded, the user can only unplug the sub-board, and the base plate remains in the network device. In this way, the service processing module of the base plate can still perform service processing, ensuring that the service processing capacity of the network device remains unchanged. In addition, since the sub-board does not occupy a slot alone, the slot of the network device that the single board provided by the present disclosure needs to occupy remains unchanged, and the number of service boards of the network device will not be reduced.

In a possible implementation, the service processing module includes one or more of a switching module, a message identification and analysis module, and a clock module.

The clock module may be a high-precision clock module, for example, a 1588 clock module.

When the service processing module includes a switching module, the board can also be called a main control switching board, and the network device where the board is located can be called a switching device. The switching module is used to implement the operations required by the forwarding plane. By setting the switching module on the baseboard, setting the management module on the sub-board, and setting the sub-board and the baseboard to be pluggable, when the management module fails or needs to be upgraded, the user can only unplug the sub-board, while the baseboard remains in the switching device. In this way, the switching module of the baseboard can still realize data exchange between different service boards, ensuring that the service processing capacity of the switching device remains unchanged.

In a possible implementation, the baseboard has a first connector and a backplane connector, and the daughterboard has a second connector. The second connector is used to dock with the first connector, and the backplane connector is used to dock with the backboard. When the daughterboard is inserted into the baseboard, the management module on the daughterboard is electrically connected to the service processing module on the baseboard through the first connector and the second connector.

Among them, the first connector and the second connector can be gold finger connectors or board-to-board connectors.

In a possible implementation, the first connector is electrically connected to the service processing module, and the second connector is electrically connected to the management module. When the daughter board is inserted into the base board, the first connector is electrically connected to the second connector. In this way, the management module and the service processing module are electrically connected, so that the management module can manage the service processing module.

In a possible implementation, the baseboard further includes a detection module, which is configured to: detect that the sub-board is pulled out from the baseboard, Another single board sends a first indication message, wherein the first indication message is used to instruct another single board to take over the service processing module.

When the daughter board is inserted into the base board, the management module of the daughter board is electrically connected to the detection module of the base board.

The technical solution provided by the present disclosure sets a detection module on the baseboard so that when a daughter board is unplugged from the baseboard, the detection module can promptly detect the unplugging of the daughter board and promptly notify another single board to take over the business processing module, thereby avoiding the business processing module being in an unmanaged state for a long time and ensuring the reliability of the operation of the network equipment.

In a possible implementation, the management module is also used to manage the detection module, and the first indication message is also used to instruct another board to take over the detection module.

In a possible implementation, the first connector is also electrically connected to the detection module, so that the detection module is electrically connected to the management module of the daughter board.

In a possible implementation, the detection module is a field-programmable gate array (FPGA), wherein the detection module can be electrically connected to a detection module of another single board through a wire.

The technical solution provided by the present disclosure, by setting the detection module as FPGA, enables the detection module to detect the removal of the daughter board more quickly and notify another single board in time.

In a possible implementation, before the daughter board is pulled out from the baseboard, the management module is configured to: obtain a prompt message, where the prompt message is used to prompt that the daughter board is about to be pulled out from the baseboard, and set the management module to standby.

The technical solution provided by the present disclosure is that before the daughter board is pulled out from the base board, the user triggers a prompt message. After the management module obtains the prompt message, the management module on the pulled out daughter board can be set as standby, and correspondingly, the management module on another single board is set as primary. In this way, first, the operation of active-standby switching does not need to be performed after the daughter board is pulled out, so that after the daughter board is pulled out, the operations required to be performed by the network device are reduced, and the other single board can take over the business processing module more quickly. Second, before the daughter board is pulled out, the communication of the network device is normal, so the active-standby switching can be performed more reliably. Third, since the database is generally stored in the primary management module, performing active-standby switching in advance can ensure that the database is completely copied to the standby management module (the standby management module is subsequently switched to the primary), thereby avoiding data loss in the database.

In a possible implementation, before the daughter board is pulled out from the baseboard, the management module is configured to: obtain a prompt message, the prompt message is used to prompt that the daughter board will be pulled out from the baseboard, stop managing the service processing module, and send a second indication message to another single board, the second indication message is used to instruct the other single board to take over the service processing module.

The technical solution provided by the present disclosure is that before the daughter board is pulled out from the base board, the user triggers a prompt message, and after the management module obtains the prompt message, the management switch is performed, without having to wait until the daughter board is pulled out before performing the management switch. That is, after the management module obtains the prompt message, the management module stops managing the service processing module and notifies another single board to take over the service processing module. In this way, when the daughter board is subsequently pulled out from the base board, the instantaneous service processing module will not be in an unmanaged state, thereby ensuring the reliability of the network device.

In a possible implementation, the sub-board further has an operating element, which is used for a user to operate before the sub-board is pulled out from the base board. When the operating element is operated, the management module is triggered to obtain a prompt message. The operating element may be located on a sub-board panel of the sub-board, and the operating element may be a button.

In a possible implementation, after the daughter board is inserted into the baseboard, the management module is configured to: send a third indication message to another single board, the third indication message is used to instruct the other single board to stop managing the service processing module. Take over the service processing module.

The technical solution provided by the present disclosure is that after the daughter board is inserted into the base board, the management module can notify another single board to stop managing the business processing module, and at the same time, take over the business processing module again to reduce the burden of the other single board.

In a possible implementation, the management module is configured to: obtain a fourth indication message, the fourth indication message being used to instruct the management module to take over another single board. Take over another single board. The fourth indication message may be triggered by a sub-board of another single board being pulled out from a baseboard, or may be triggered by an operating member of a sub-board of another single board being operated.

The technical solution provided by the present disclosure is that when a daughter board in another single board is pulled out, the management module takes over the other single board to avoid the business processing module of the other single board being in an unmanaged state for a long time, thereby ensuring the reliability of the operation of the network equipment.

In a possible implementation manner, the management module is configured to: receive the fourth indication message through the first detection module.

In a possible implementation, the management module is further configured to: receive a fifth indication message sent by another single board, the fifth indication message being used to instruct the management module to stop managing the other single board. Stop managing the other single board.

The technical solution provided by the present disclosure is that when a daughter board in another single board is inserted, the other single board notifies the management module to stop managing the other single board, and the management module of the other single board takes over its own business processing module.

In a possible implementation, the base plate has a slide rail, and the sub-board is slidably connected to the slide rail, so that the plugging and unplugging of the sub-board is smoother.

In a possible implementation, the daughter board panel of the daughter board has a handle, and the handle is used for a user to hold.

DETAILED DESCRIPTION

Switching equipment, such as optical line termination (OLT), undertakes important tasks such as routing learning and data packet forwarding. Switching equipment has a control plane and a forwarding plane.

The control plane refers to the part of the switching device used to transmit instructions and calculate table items. For example, routing protocol learning, protocol message forwarding, protocol table item calculation, and routing table item maintenance all fall into the category of the control plane. The forwarding plane refers to the part of the switching device used to encapsulate and forward data messages. For example, the reception, decapsulation, encapsulation, routing table lookup, and forwarding of data messages all fall into the category of the forwarding plane.

In order to ensure the stability of the switching equipment, the control plane and the forwarding plane are generally designed to be relatively independent and not affect each other. In this way, when the control plane of the switching equipment temporarily fails, the forwarding plane can continue to work, thereby ensuring that the original services in the network are not affected by system failures and improving the reliability of the entire network.

The control plane and forwarding plane can be physically separated or logically separated. Due to cost constraints, some switching devices, such as OLT devices, use a logical separation technology solution. That is, after the switching device is started, the switching device divides the central processing unit (CPU) resources and memory resources to different processes, some of which are responsible for learning routes and some for message forwarding.

For example, as shown in Fig. 1, a schematic diagram of a switching device is provided, the switching device has two main control switching boards 100 and multiple service boards 200, and the two main control switching boards 100 are mutually active and standby. In addition, a backplane 300 is also provided inside the switching device, and the main control switching boards 100 and the service boards 200 are electrically connected through the backplane 300.

As shown in FIG2 , the main control switch board 100 has a management module 21 and a switch module 11. The management module 21 is used to manage the switch module 11, and the switch module 11 is used to implement data exchange between different service boards 200. The management module 21 and the switch module 11 can be integrated in the same hardware. In addition, the main control switch board 100 also includes basic configurations such as a backplane connector 15, a power interface 16, a power module 17, and a clock module 18.

As shown in FIG2 , since the control plane and the forwarding plane are integrated on a main control switch board 100 without physical separation, when the management module 21 fails or needs to be upgraded, the main control switch board 100 needs to be unplugged. However, this will make the switching module 11 of the main control switch board 100 unable to work (has been unplugged), resulting in a reduction of half of the switching capacity of the switching device.

In the related art, in order to achieve physical separation of the control plane and the forwarding plane, as shown in FIG3 , the management module 21 and the switching module 11 are respectively made into independent boards, that is, they are respectively made into a main control board 400 and a switching board 500. In this way, when the management module 21 fails or needs to be upgraded, only the main control board 400 needs to be pulled out, and the switching board 500 still remains in the switching device and realizes data exchange between different service boards 200, thereby not affecting the switching capacity of the switching device.

However, since both the main control board 400 and the switch board 500 need to occupy slots, and the main control board 400 and the switch board 500 require dual backup, two main control boards 400 and two switch boards 500 need to occupy four slots, which will reduce the number of business boards 200 that can be inserted into the switching device.

In view of the above technical problems, an embodiment of the present disclosure provides a main control switch board 100, which can achieve physical separation of the control plane and the forwarding plane without reducing the number of service boards 200 of the switching device.

The following is an exemplary description of the main control switch board 100 provided in the embodiment of the present disclosure:

As shown in Fig. 4 to Fig. 7, the main control switch board 100 includes a baseboard 1 and a subboard 2, and the subboard 2 is pluggable and connected to the baseboard 1. The baseboard 1 has a switch module 11, and the switch module 11 is used to realize data exchange between different service boards 200. The subboard 2 has a management module 21, and the management module 21 is used to manage the switch module 11.

The bottom plate 1 occupies a slot of the switching device, and has a switching module 11, which is used to implement the operations required by the forwarding plane. In addition, the bottom plate 1 also has basic configuration modules such as a power interface 16, a power module 17, and a clock module 18. Moreover, when the switching device also has a backplane 300, the bottom plate 1 also has a backplane connector 15.

The daughterboard 2 can be plugged in and out of the baseboard 1, and the daughterboard 2 does not occupy a slot of the switching device alone. The daughterboard 2 has a management module 21, which is used to implement operations required by the control plane. The management module 21 can also be called a control module.

In some examples, as shown in FIG7 , the management module 21 includes a processor 211 and a memory 212. The processor 211 may be a CPU, and the memory 212 includes a read-only memory (ROM) 2121 and a random access memory (RAM) 2122. The read-only memory 2121 may be a flash memory, and the random access memory 2122 may be a double data rate synchronous dynamic random access memory (DDR SDRAM).

In addition, the management module 21 can be used to manage other modules on the baseboard 1 in addition to managing the switch module 11 , that is, the management module 21 is used to manage the baseboard 1 . Furthermore, the management module 21 is also used to manage the service board 200 .

The technical solution provided by the embodiment of the present disclosure is to set the switching module 11 on the baseboard 1, set the management module 21 on the sub-board 2, and set the sub-board 2 and the baseboard 1 to be pluggable, so that when the management module 21 fails or needs to be upgraded, the user can only unplug the sub-board 2, while the baseboard 1 remains in the switching device. In this way, the switching module 11 on the baseboard 1 can still realize data exchange between different service boards 200, ensuring that the switching capacity of the switching device remains unchanged.

In addition, since the sub-board 2 does not occupy a slot alone, the two main control switch boards 100 that serve as the master and backup for each other still only need to occupy two slots of the switch device, and the number of service boards 200 of the switch device will not be reduced.

The following is an exemplary description of the implementation method of the pluggable connection between the sub-board 2 and the baseboard 1:

In some examples, as shown in FIG. 5 , the panel 10 of the base plate 1 has an opening 101 , and the sub-board 2 is used to be inserted into the base plate 1 through the opening 101 , or to be pulled out from the base plate 1 .

In some examples, as shown in FIG5 and FIG6 , the baseboard 1 has a first connector 13 , and the first connector 13 is electrically connected to the switch module 11 . The daughterboard 2 has a second connector 23 , and the second connector 23 is electrically connected to the management module 21 .

When the daughter board 2 is inserted into the base board 1, the first connector 13 is electrically connected to the second connector 23. Thus, the management module 21 is electrically connected to the switch module 11, so that the management module 21 can manage the switch module 11.

Among them, the first connector 13 and the second connector 23 can be gold finger connectors, or board-to-board connectors, etc.

In some examples, as shown in FIG. 5 and FIG. 6 , the base plate 1 has a slide rail 14 , and the sub-board 2 is slidably connected to the slide rail 14 , thereby facilitating the insertion and removal of the sub-board 2 .

In some examples, as shown in FIG. 5 and FIG. 6 , the daughterboard panel 20 of the daughterboard 2 has a handle 24 , and the handle 24 is used for a user to hold, so as to facilitate the user to insert or remove the daughterboard 2 .

In some examples, as shown in Figures 5 and 6, the sub-board 2 has an operating member 22, and the operating member 22 is used for the user to operate before the sub-board 2 is pulled out from the base plate 1. And when the operating member 22 is operated, the trigger management module 21 receives a prompt message, which is used to prompt that the sub-board 2 is about to be pulled out.

The operating element 22 is electrically connected to the management module 21. As shown in Figures 5 and 6, the operating element 22 may be a button, and the user triggers the prompt message by pressing the operating element 22.

After the management module 21 obtains the prompt message, it can perform the preparation operation of the sub-board 2. The specific operation of the management module 21 after receiving the prompt message will be described below.

In some examples, as shown in FIG. 8 , the baseboard 1 further includes a detection module 12 , and the detection module 12 is used to detect whether the sub-board 2 is pulled out.

In some examples, the detection module 12 is electrically connected to the first connector 13, and there is a daughter board presence indication between the first connector 13 and the second connector 23. When the daughter board 2 is pulled out from the base plate 1, the first connector 13 and the second connector 23 are disconnected, and the detection module 12 can detect that the daughter board 2 is not in place and can immediately notify another main control switch board 100.

In addition, the management module 21 is also used to manage the detection module 12 .

In some examples, the detection module 12 is connected to the detection module 12 of another main control switch board 100, and the message transmitted by the connection can be whether the main control switch board 100 is active or standby, whether the sub-board 2 of the main control switch board 100 is in place, and the management module of the main control switch board 100. Whether block 21 is running normally, etc.

In some examples, the detection module 12 is a field-programmable gate array (FPGA). Thus, compared with the CPU of another main control switch board 100 detecting whether the sub-board 2 of the main control switch board 100 is unplugged, the detection module 12 can detect the unplugging of the sub-board 2 more quickly and notify the other main control switch board 100 in time.

Among them, FPGA is faster than CPU, which is essentially determined by the architecture of FPGA without instructions and shared memory. CPU belongs to Feng structure, and in Feng structure, since the execution unit can execute any instruction, it needs instruction memory, decoder, arithmetic unit of various instructions, and branch jump processing logic. The function of each logic unit of FPGA is determined during programming, no instructions are required, and the functions of each logic unit can be processed in parallel. Therefore, FPGA detects whether sub-board 2 is pulled out faster.

In other examples, the detection module 12 may also be other chips with communication capabilities, and the embodiments of the present disclosure do not limit the specific type of the detection module 12.

After the daughter board 2 is pulled out from the base board 1 , the management module 21 on the daughter board 2 can no longer manage the switch module 11 , and the switch module 11 is in an unmanaged state for a long time, which affects the reliability of the switch device.

Since the switching device generally has two main control switching boards 100, when the daughter board 2 in one main control switching board 100 is unplugged, the other main control switching board 100 can take over the switching module 11 of the main control switching board 100 that has been unplugged. Thus, the switching module 11 is prevented from being in an unmanaged state for a long time, and the reliability of the switching device is ensured.

9, taking two main control switch boards 100 as an example, the management subjects of the switch modules 11 of the two main control switch boards 100 in various states are described as follows:

First, the connection relationship between the first main control switch board 110 and the second main control switch board 120 is described:

As shown in FIG9 , for the convenience of description, the baseboard 1, the subboard 2, the switching module 11, and the management module 21 of the first main control switching board 110 are respectively referred to as the first baseboard 111, the first subboard 112, the first switching module 1111, and the first management module 1121. The baseboard 1, the subboard 2, the switching module 11, and the management module 21 of the second main control switching board 120 are respectively referred to as the second baseboard 121, the second subboard 122, the second switching module 1211, and the second management module 1221.

In some examples, as shown in FIG. 9 , the first main control switch board 110 and the second main control switch board 120 communicate with each other through the backplane 300 .

In some examples, the first management module 1121 can manage the first switching module 1111 through the first management interface, and can manage the second switching module 1211 through the backplane connection and the first management interface. Correspondingly, the second management module 1221 can manage the second switching module 1211 through the first management interface, and can manage the first switching module 1111 through the backplane connection and the first management interface.

Among them, the above-mentioned first management interface is a peripheral component interconnect express (PCIe) management interface, a serial management interface or a parallel management interface.

In some examples, the first management interfaces of the first switching module 1111 and the second switching module 1211 are integrated with a two-or-one switch. The first switching module 1111 and the second switching module 1211 can be managed by the first management module 1121 or the second management module 1221 by operating the two-or-one switch.

In some other examples, the two-or-one switch may also be independent of the first switching module 1111 and the second switching module 1211. In this case, the detection module 12 may operate the two-or-one switch.

In some examples, as shown in FIG. 9 , a line is provided between the first management module 1121 and the second management module 1221 , so that the first management module 1121 and the second management module 1221 can communicate directly with each other.

In addition, for the case where the main control switching board 100 also includes a detection module 12, for the sake of convenience of description, as shown in Figure 9, the detection module 12 of the first main control switching board 110 is called the first detection module 1112, and the detection module 12 of the second main control switching board 120 is called the second detection module 1212.

In some examples, the first management module 1121 can manage the first detection module 1112 through the second management interface, and can manage the second detection module 1212 through the backplane connection and the second management interface. Correspondingly, the second management module 1221 can manage the second detection module 1212 through the second management interface, and can manage the first detection module 1112 through the backplane connection and the second management interface.

Among them, the above-mentioned second management interface is a serial peripheral interface (SPI) management interface, a serial management interface or a parallel management interface.

In some examples, the second management interface is integrated with a two-or-one switch, and the first detection module 1112 and the second detection module 1212 can choose to be managed by the first management module 1121 or the second management module 1221 by operating the two-or-one switch.

In some examples, as shown in FIG9 , there is a connection between the first detection module 1112 and the second detection module 1212. The connection can be implemented through the backplane 300, and the message transmitted by the connection can be whether the main control switch board 100 is active or standby, whether the sub-board 2 of the main control switch board 100 is in place, and whether the management module 21 of the main control switch board 100 is operating normally.

Next, the management methods of the first switching module 1111 and the second switching module 1211 in various states are described:

(1) The first sub-board 112 and the second sub-board 122 are both in place

In some examples, when both the first sub-board 112 and the second sub-board 122 are in place, the first management module 1121 manages the first switching module 1111, and the second management module 1221 manages the second switching module 1211. This management mode may be referred to as a load sharing mode.

In other examples, when the first sub-board 112 and the second sub-board 122 are both in place, the active management module 21 (one of the first management module 1121 and the second management module 1221) simultaneously manages the first switching module 1111 and the second switching module 1211. This management mode may be referred to as an active-standby mode.

(2) The first sub-board 112 is pulled out from the first base board 111

In some examples, when the first sub-board 112 is unplugged from the first baseboard 111, the second management module 1221 obtains a first indication message, the first indication message is used to instruct the second management module 1221 to take over the first switching module 1111, and the first indication message is triggered by the first sub-board 112 being unplugged from the first baseboard 111. Afterwards, in response to the first indication message, the second management module 1221 takes over the first switching module 1111.

The technical solution provided by the embodiment of the present disclosure, by setting a first indication message to be triggered when the first sub-board 112 is unplugged from the first base board 111, and setting the second management module 1221 to take over the first switching module 1111 after obtaining the first indication message, avoids the situation where the first switching module 1111 is in an unmanaged state for a long time after the first sub-board 112 is unplugged from the first base board 111, and ensures the reliability of the switching equipment.

The embodiment of the present disclosure does not limit the implementation manner in which the second management module 1221 obtains the first indication message. An exemplary description is given below:

In some examples, as shown in FIG10 , the second management module 1221 obtains the first indication message including the following steps:

In step 1001 , the first detection module 1112 detects that the first sub-board 112 is pulled out from the first base board 111 .

In step 1002 , the first detection module 1112 sends a first indication message to the second detection module 1212 .

In step 1003 , the second detection module 1212 sends a first indication message to the second management module 1221 .

Afterwards, in step 1004 , the second management module 1221 receives the first indication message and takes over the first switching module 1111 .

The technical solution provided by the embodiment of the present disclosure improves the detection speed by having the first detection module 1112 detect whether the first sub-board 112 is pulled out from the first baseboard 111, so that the second management module 1221 can take over the first switching module 1111 more quickly.

In some other examples, as shown in FIG11 , the second management module 1221 obtains the first indication message including the following steps:

In step 1101 , the first detection module 1112 detects that the first sub-board 112 is pulled out from the first base board 111 .

In step 1102 , the first detection module 1112 sends a first indication message to the second management module 1221 .

Afterwards, in step 1103 , the second management module 1221 receives the first indication message, and the second management module 1221 takes over the first switching module 1111 .

For the technical solution shown in Figure 11, since the first detection module 1112 sends a message to the second management module 1221 through the connection between the first detection module 1112 and the second management module 1221, the connection between the first detection module 1112 and the second detection module 1212 can be removed, and the architecture of the switching device after the removal is shown in Figure 12.

In some other examples, as shown in FIG13 , the second management module 1221 obtains the first indication message including the following steps:

In step 1301 , the second management module 1221 detects that the first sub-board 112 is pulled out from the first baseboard 111 . That is, the first indication message is detected by the second management module 1221 .

Afterwards, in step 1302 , the second management module 1221 takes over the first switching module 1111 .

For the technical solution shown in FIG. 13 , since the first detection module 1112 and the second detection module 1212 are not required to participate, the first detection module 1112 and the second detection module 1212 can be removed. The architecture of the switching device after removing the first detection module 1112 and the second detection module 1212 is shown in FIG. 14 .

In addition, in the case where the first sub-board 112 has an operating member 22, the user can operate the operating member 22 before the first sub-board 112 is pulled out from the first base plate 111. As shown in FIG15 , after the user operates the operating member 22, the switching device performs the following processing:

In step 1501, the first management module 1121 obtains a prompt message.

The prompt message is used to prompt that the first sub-board 112 is about to be pulled out from the first base board 111 .

In step 1502, the first management module 1121 sets the first management module 1121 as a standby, and correspondingly, the second management module 1221 sets the second management module 1221 as a master.

In this way, first, the master-slave switching operation does not need to be performed after the first sub-board 112 is unplugged, so that after the first sub-board 112 is unplugged, the operations required by the switching device are reduced, and the second management module 1221 can take over the first switching module 1111 more quickly. Second, before the first sub-board 112 is unplugged, since the communication between the first main control switching board 110 and the second main control switching board 120 is normal, the master-slave switching can be performed more reliably. Third, since the database is generally stored in the active management module 21, performing the active-slave switching in advance can ensure that the database is completely copied to the standby management module 21 (the standby management module 21 is subsequently switched to the active one), avoiding the data in the database. Data is lost.

The specific processing of step 1503 to step 1506 is the same as the specific processing of step 1001 to step 1004, and will not be repeated here.

Of course, in some other examples, the primary and standby switching may be performed after the first sub-board 112 is pulled out from the first baseboard 111 , and the embodiments of the present disclosure are not limited to this.

In other examples, after the user operates the operating element 22, as shown in FIG16 , the switching device performs the following processing:

In step 1601, the first management module 1121 obtains a prompt message.

The prompt message is used to prompt that the first sub-board 112 is about to be pulled out from the first base board 111 .

In step 1602 , the first management module 1121 stops managing the first switching module 1111 .

In step 1603 , the first management module 1121 sends a second indication message to the first detection module 1112 .

In step 1604 , the first detection module 1112 sends a second indication message to the second detection module 1212 .

In step 1605 , the second detection module 1212 sends a second indication message to the second management module 1221 .

In step 1606 , the second management module 1221 receives the second indication message and takes over the first switching module 1111 .

According to the technical solution provided by the embodiment of the present disclosure, after the first management module 1121 obtains the prompt message, it can directly perform management switching without having to wait until the first daughter board 112 is unplugged before performing management switching. In this way, when the first daughter board 112 is subsequently unplugged from the first base board 111, the first switching module 1111 will not be in an unmanaged state instantaneously, thereby ensuring the reliability of the switching device.

In addition, the first management module 1121 may also use other transmission paths to send the second indication message to the second management module 1221. For example, the first management module 1121 sends the second indication message to the second management module 1221 through the connection between the first management module 1121 and the second management module 1221. For another example, the second detection module 1212 sends the second indication message to the second management module 1221 through the connection between the second detection module 1212 and the second management module 1221.

Since the user may not unplug the first sub-board 112 from the first baseboard 111 after triggering the prompt message, in the case where the switching device adopts the load sharing mode, after the second management module 1221 takes over the first switching module 1111, if the first sub-board 112 is not unplugged from the first baseboard 111 within the target time length, the second management module 1221 stops managing the first switching module 1111, and the first management module 1121 takes over the first switching module 1111. Thus, the burden of the second management module 1221 is reduced.

Exemplarily, when the second management module 1221 does not receive the indication message sent by the first detection module 1112 to instruct the first sub-board 112 to be unplugged within the target time length, the second management module 1221 stops managing the first switching module 1111 and notifies the first management module 1121 to take over the first switching module 1111.

It should be noted that when the switching device adopts the master-slave mode, even if the first sub-board 112 is not unplugged from the first baseboard 111 within the target time, the first switching module 1111 and the second switching module 1211 can still be managed simultaneously by the second management module 1221 without having to switch back to management by the first management module 1121.

In addition, correspondingly, when the second sub-board 122 is pulled out from the second baseboard 121, the first management module 1121 obtains the fourth indication message, which is used to instruct the first management module 1121 to take over the second switching module 1211. Afterwards, the first management module 1121 takes over the second switching module 1211.

Regarding the specific processing performed by the switching device when the second sub-board 122 is pulled out from the second base board 121, reference can be made to the processing performed by the switching device when the first sub-board 112 is pulled out from the first base board 111, which will not be repeated here.

It should also be noted that, for the case where the switching device adopts the master-slave mode, if before the first sub-board 112 is unplugged from the first base board 111, the first management module 1121 is the backup management module 21, and the second management module 1221 is the master management module 21, then after the first sub-board 112 is unplugged from the first base board 111, the switching device may not perform any processing.

(3) The first sub-board 112 is inserted into the first base board 111

In some examples, after the first sub-board 112 is inserted into the first baseboard 111 , the first management module 1121 re-manages the first switching module 1111 to reduce the burden of the second management module 1221 .

Exemplarily, after the first sub-board 112 is inserted into the first baseboard 111, the first management module 1121 sends a third indication message, and the third indication message is used to instruct the second management module 1221 to stop managing the first switching module 1111. After receiving the third indication message, the second management module 1221 stops managing the first switching module 1111, and the first management module 1121 takes over the first switching module 1111.

Next, the processing performed by the switching device after the first sub-board 112 is inserted into the first baseboard 111 is exemplarily described:

In some examples, as shown in FIG10 , the processing performed by the switching device includes the following steps:

In step 1005, the first management module 1121 is started.

After the first sub-board 112 is inserted into the first baseboard 111 , it takes a certain amount of time for the first management module 1121 to start up.

In step 1006 , the first management module 1121 sends a third indication message to the first detection module 1112 .

In step 1007 , the first detection module 1112 sends a third indication message to the second detection module 1212 .

In step 1008 , the second detection module 1212 sends a third indication message to the second management module 1221 .

In step 1009 , the second management module 1221 receives the third instruction message and stops managing the first switching module 1111 .

In step 1010 , the first management module 1121 takes over the first switching module 1111 .

The specific processing of step 1507 to step 1512 is the same as the specific processing of step 1005 to step 1010, and will not be repeated here.

In some other examples, as shown in FIG11 , the processing performed by the switching device includes the following steps:

In step 1104, the first management module 1121 is started.

In step 1105 , the first management module 1121 sends a third indication message to the first detection module 1112 .

In step 1106 , the first detection module 1112 sends a third indication message to the second management module 1221 .

In step 1107 , the second management module 1221 receives the third instruction message and stops managing the first switching module 1111 .

In step 1108 , the first management module 1121 takes over the first switching module 1111 .

For the technical solution shown in Figure 11, since the first detection module 1112 sends the third indication message to the second management module 1221 through the connection between the first detection module 1112 and the second management module 1221, the independent connection between the first detection module 1112 and the second detection module 1212 can be removed, and the architecture of the switching device after the removal is shown in Figure 12.

In other examples, as shown in FIG13 , the processing performed by the switching device includes the following steps:

In step 1303, the first management module 1121 is started.

In step 1304 , the first management module 1121 sends a third indication message to the second management module 1221 .

In step 1305 , the second management module 1221 stops managing the first switching module 1111 .

In step 1306 , the first management module 1121 takes over the first switching module 1111 .

For the technical solution shown in FIG. 13 , since the first detection module 1112 and the second detection module 1212 are not required to participate, the first detection module 1112 and the second detection module 1212 can be removed. The architecture of the switching device after removing the first detection module 1112 and the second detection module 1212 is shown in FIG. 14 .

In addition, correspondingly, after the second sub-board 122 is inserted into the second baseboard 121, the first management module 1121 receives the fifth instruction message sent by the second management module 1221, and the fifth instruction message is used to instruct the first management module 1121 to stop managing the second switching module 1211. In response to the fifth instruction message, the first management module 1121 stops managing the second switching module 1211. Afterwards, the second management module 1221 can take over the second switching module 1211.

Regarding the specific processing performed by the switching device after the second sub-board 122 is inserted into the second base board 121, reference can be made to the processing performed by the switching device when the first sub-board 112 is inserted into the first base board 111, and will not be repeated here.

It should be noted that, in the case where the switching device adopts the active-standby mode, after the first sub-board 112 is inserted into the first baseboard 111, it can be set that the second management module 1221 still manages the first switching module 1111 and the second switching module 1211 at the same time. The first management module 1121 takes over the first switching module 1111 and the second switching module 1211 only after the second management module 1221 fails or the second sub-board 122 is pulled out.

It should be noted that the above-mentioned switching module 11 can also be replaced by other service processing modules, such as a message identification and parsing module and a clock module. Then the above-mentioned switching module 11 can be expanded into a service processing module, and the above-mentioned first switching module 1111 and the second switching module 1211 can also be expanded into a first service processing module and a second service processing module. Among them, the clock module can be a high-precision clock module, an Ethernet synchronization clock module, for example, a 1588 clock module.

That is, the disclosed embodiment also provides a single board.

This management mode may be referred to as a load sharing mode.

In some examples, when the first sub-board 112 and the second sub-board 122 are both in place, the active management module 21 (one of the first management module 1121 and the second management module 1221) simultaneously manages the first switching module 1111 and the second switching module 1211. This management mode may be referred to as an active-standby mode.

In some examples, as shown in FIG. 18 , the first base plate 111 further has a first detection module 1112 , and the second base plate 121 further has a second detection module 1212 .

In some examples, the first detection module 1112 and the second detection module 1212 are both FPGAs.

In some examples, the second management module 1221 is configured to: obtain a first indication message, the first indication message is used to instruct the second management module 1221 to take over the first switching module 1111, and the first indication message is triggered by the first sub-board 112 being pulled out from the first baseboard 111. Take over the first switching module 1111.

After the second management module 1221 takes over the first switching module 1111 , the second management module 1221 manages the first switching module 1111 and the second switching module 1211 at the same time.

The technical solution provided by the embodiment of the present disclosure, by setting a first indication message to be triggered when the first sub-board 112 is unplugged from the first base board 111, and setting the second management module 1221 to take over the first switching module 1111 after obtaining the first indication message, avoids the situation where the first switching module 1111 is in an unmanaged state for a long time after the first sub-board 112 is unplugged from the first base board 111, and ensures the reliability of the switching equipment.

In some examples, as shown in FIG10 , the first detection module 1112 is configured to: detect that the first sub-board 112 is pulled out from the first baseboard 111, and send a first indication message to the second detection module 1212, where the first indication message is used to instruct the second management module 1221 to take over the first switching module 1111. The second detection module 1212 is configured to: send the first indication message to the second management module 1221. The second management module 1221 is configured to: receive the first indication message and take over the first switching module 1111.

In some examples, as shown in FIG11 , the first detection module 1112 is configured to: detect that the first sub-board 112 is pulled out from the first baseboard 111, and send a first indication message to the second management module 1221 through the connection between the first detection module 1112 and the second management module 1221. The second management module 1221 is configured to: receive the first indication message and take over the first switching module 1111.

In some examples, as shown in FIG13 , the second management module 1221 is configured to: detect that the first sub-board 112 is unplugged, and take over the first switching module 1111. That is, the first indication message is detected by the second management module 1221.

In some examples, as shown in FIG. 15 , before the first sub-board 112 is pulled out from the first baseboard 111, the first management module 1121 is further configured to: obtain a prompt message, the prompt message being used to prompt that the first sub-board 112 is about to be pulled out from the first baseboard 111, and the first management module 1121 Set as backup.

According to the technical solution provided by the embodiment of the present disclosure, before the first sub-board 112 is pulled out from the first base board 111, the user triggers a prompt message. After the first management module 1121 obtains the prompt message, it can set itself as a backup and notify the second management module 1221 to set it as the primary.

In this way, first, the operation of active-standby switching does not need to be performed after the first sub-board 112 is unplugged, so that after the first sub-board 112 is unplugged, the operations required by the switching device are reduced, and the second management module 1221 can take over the first switching module 1111 more quickly. Second, before the first sub-board 112 is unplugged, since the communication between the first main control switching board 110 and the second main control switching board 120 is normal, the active-standby switching can be performed more reliably. Third, since the database is generally stored in the active management module 21, performing active-standby switching in advance can ensure that the database is completely copied to the standby management module 21 (the standby management module 21 is subsequently switched to the active one), thereby avoiding data loss in the database.

In some examples, as shown in FIG16 , before the first sub-board 112 is pulled out from the first baseboard 111, the first management module 1121 is further configured to: obtain a prompt message, the prompt message is used to prompt that the first sub-board 112 is about to be pulled out from the first baseboard 111, stop managing the first switching module 1111, and send a second indication message to the second management module 1221, the second indication message is used to instruct the second management module 1221 to take over the first switching module 1111. The second management module 1221 is configured to: receive the second indication message, and take over the first switching module 1111.

According to the technical solution provided by the embodiment of the present disclosure, before the first daughter board 112 is pulled out from the first base board 111, the user triggers a prompt message, and after the first management module 1121 obtains the prompt message, it directly performs management switching, without having to wait until the first daughter board 112 is pulled out before performing management switching. In this way, when the first daughter board 112 is subsequently pulled out from the first base board 111, the first switching module 1111 will not be in an unmanaged state instantaneously, thereby ensuring the reliability of the switching device.

In some examples, after the first sub-board 112 is inserted into the first baseboard 111, as shown in FIG. 10, FIG. 11, or FIG. 13, the first management module 1121 is configured to: send a third indication message to the second management module 1221, and the third indication message is used to instruct the second management module 1221 to stop managing the first switching module 1111. The second management module 1221 is configured to: receive the third indication message and stop managing the first switching module 1111. The first management module 1121 is also configured to: take over the first switching module 1111.

According to the technical solution provided by the embodiment of the present disclosure, after the first sub-board 112 is inserted into the first baseboard 111, the first management module 1121 notifies the second management module 1221 to stop managing the first switching module 1111, and the first management module 1121 takes over the first switching module 1111 again, thereby reducing the burden on the second management module 1221.

It should be noted that the first switching module 1111 and the second switching module 1211 may also be replaced by other service processing modules, such as a message identification and parsing module and a clock module, etc. Then the first switching module 1111 and the second switching module 1211 may also be expanded to a first service processing module and a second service processing module, and the switching device may also be replaced by a network device.

The embodiment of the present disclosure further provides a management method, which is applied to the above network device. As shown in FIG19 , the management method includes the following steps:

In step 1901, the second management module 1221 obtains a first indication message.

The first indication message is used to instruct the second management module 1221 to take over the first switching module 1111 , and the first indication message is triggered by the first sub-board 112 being pulled out from the first baseboard 111 .

The following is an exemplary description of the implementation manner in which the second management module 1221 obtains the first indication message:

In some examples, as shown in FIG10 , the second management module 1221 obtains the first indication message including the following steps:

In step 1001 , the first detection module 1112 detects that the first sub-board 112 is pulled out from the first base board 111 .

In step 1002 , the first detection module 1112 sends a first indication message to the second detection module 1212 .

In step 1003 , the second detection module 1212 sends a first indication message to the second management module 1221 .

In step 1004 , the second management module 1221 receives the first indication message and takes over the first switching module 1111 .

In some other examples, as shown in FIG11 , the second management module 1221 obtains the first indication message including the following steps:

In step 1101 , the first detection module 1112 detects that the first sub-board 112 is pulled out from the first base board 111 .

In step 1102 , the first detection module 1112 sends a first indication message to the second management module 1221 through the connection between the first detection module 1112 and the second management module 1221 .

In step 1103 , the second management module 1221 receives the first indication message and takes over the first switching module 1111 .

In some other examples, as shown in FIG13 , the second management module 1221 obtains the first indication message including the following steps:

In step 1301, the second management module 1221 detects that the first sub-board 112 is unplugged. That is, the first indication message is detected by the second management module.

In step 1302 , the second management module 1221 takes over the first switching module 1111 .

In addition, in the case where the first sub-board 112 has the operating member 22 , the user may operate the operating member 22 before pulling out the first sub-board 112 . Correspondingly, as shown in FIG15 , after the user operates the operating element 22, the management method further includes the following steps:

In step 1501, the first management module 1121 obtains a prompt message.

The prompt message is used to prompt that the first sub-board 112 is about to be pulled out from the first base board 111 .

In step 1502, the first management module 1121 sets the first management module 1121 as a standby, and correspondingly, the second management module 1221 is set as a master.

In this way, first, the operation of active-standby switching does not need to be performed after the first sub-board 112 is unplugged, so that after the first sub-board 112 is unplugged, the operations required by the switching device are reduced, and the second management module 1221 can take over the first switching module 1111 more quickly. Second, before the first sub-board 112 is unplugged, since the communication between the first main control switching board 110 and the second main control switching board 120 is normal, the active-standby switching can be performed more reliably. Third, since the database is generally stored in the active management module 21, performing active-standby switching in advance can ensure that the database is completely copied to the standby management module 21 (the standby management module 21 is subsequently switched to the active one), thereby avoiding data loss in the database.

The active/standby switching operation does not need to be performed after the first sub-board 112 is unplugged, so that after the first sub-board 112 is unplugged, the operations required by the switching device are reduced, and the second management module 1221 can take over the first switching module 1111 more quickly.

In some examples, after setting the first management module 1121 as a standby, the first management module 1121 sends an indication message to the second management module 1221, where the indication message is used to instruct the second management module 1221 to set the second management module 1221 as a master.

In step 1902 , the second management module 1221 takes over the first switching module 1111 .

After the second management module 1221 takes over the first switching module 1111 , the second management module 1221 manages the first switching module 1111 and the second switching module 1211 at the same time.

The technical solution provided by the embodiment of the present disclosure, by setting a first indication message to be triggered when the first sub-board 112 is unplugged from the first base board 111, and setting the second management module 1221 to take over the first switching module 1111 after obtaining the first indication message, avoids the situation where the first switching module 1111 is in an unmanaged state for a long time after the first sub-board 112 is unplugged from the first base board 111, and ensures the reliability of the switching equipment.

In some examples, after the first sub-board 112 is inserted into the first baseboard 111, the management method further includes: the first management module 1121 sends a third indication message to the second management module 1221, and the third indication message is used to instruct the second management module 1221 to stop managing the first switching module 1111. The second management module 1221 receives the third indication message and stops managing the first switching module 1111. The first management module 1121 takes over the first switching module 1111.

According to the technical solution provided by the embodiment of the present disclosure, after the first sub-board 112 is inserted into the first baseboard 111, the first management module 1121 notifies the second management module 1221 to stop managing the first switching module 1111, and the first management module 1121 takes over the first switching module 1111 again, thereby reducing the burden on the second management module 1221.

The following is an exemplary description of the operations performed by the switching device after the first daughter board 112 is inserted:

In some examples, as shown in FIG. 10 , in step 1005 , the first management module 1121 is started.

In step 1006 , the first management module 1121 sends a third indication message to the first detection module 1112 .

In step 1007 , the first detection module 1112 sends a third indication message to the second detection module 1212 .

In step 1008 , the second detection module 1212 sends a third indication message to the second management module 1221 .

In step 1108 , the first management module 1121 takes over the first switching module 1111 .

In other examples, as shown in FIG. 13 , in step 1303 , the first management module 1121 is started.

In step 1304 , the first management module 1121 sends a third indication message to the second management module 1221 .

In step 1305 , the second management module 1221 stops managing the first switching module 1111 .

In step 1306 , the first management module 1121 takes over the first switching module 1111 .

It should be noted that the first switching module 1111 and the second switching module 1211 may also be replaced by other service processing modules, such as a message identification and analysis module and a clock module. Then the first switching module 1111 and the second switching module 1211 may also be expanded into a first service processing module and a second service processing module.

The present disclosure also provides a management method, which is applied to the above network device, as shown in FIG. 16. The management method comprises the following steps:

In step 2001, the first management module 1121 obtains a prompt message.

The prompt message is used to prompt that the first sub-board 112 is about to be pulled out from the first base board 111. The prompt message is triggered by the user operating the operating member 22, and the operating member 22 can be a button on the first sub-board 112.

In step 2002 , the first management module 1121 stops managing the first switching module 1111 .

In some examples, the first management module 1121 further sets the first management module 1121 as a standby. Correspondingly, the second management module 1221 sets the second management module 1221 as a master.

In step 2003 , the first management module 1121 sends a second indication message to the second management module 1221 .

The second indication message is used to instruct the second management module 1221 to take over the first switching module 1111 .

The embodiment of the present disclosure does not limit the implementation manner in which the first management module 1121 sends the second indication message to the second management module 1221. An exemplary description is given below:

In some examples, as shown in FIG. 16 , the first management module 1121 sending the second indication message to the second management module 1221 includes the following steps:

In step 1603 , the first management module 1121 sends a second indication message to the first detection module 1112 .

In step 1604 , the first detection module 1112 sends a second indication message to the second detection module 1212 .

In step 1605 , the second detection module 1212 sends a second indication message to the second management module 1221 .

In some other examples, the first management module 1121 sends the second indication message to the first detection module 1112 , and the first detection module 1112 sends the second indication message to the second management module 1221 through the connection between the first detection module 1112 and the second management module 1221 .

In some other examples, the first management module 1121 sends the second indication message to the second management module 1221 through the connection between the first management module 1121 and the second management module 1221 .

It should be noted that the embodiment of the present disclosure does not limit the order of step 2002 and step 2003. Step 2002 can be located before step 2003 or after step 2003. Step 2002 and step 2003 can also be performed simultaneously.

In step 2004 , the second management module 1221 receives the second instruction message and takes over the first switching module 1111 .

After the second management module 1221 takes over the first switching module 1111 , the second management module 1221 manages the first switching module 1111 and the second switching module 1211 at the same time.

According to the technical solution provided by the implementation of the present disclosure, before the first daughter board 112 is pulled out from the first base board 111, the user triggers a prompt message, and after the first management module 1121 obtains the prompt message, it directly performs management switching, without having to wait until the first daughter board 112 is pulled out before performing management switching. In this way, when the first daughter board 112 is subsequently pulled out from the first base board 111, the first switching module 1111 will not be in an unmanaged state instantaneously, thereby ensuring the reliability of the switching device.

In addition, after the user triggers the prompt message, the first daughter board 112 may not be pulled out from the first base board 111. In this case, for switching devices using different management modes, the switching devices have different processing methods:

In some examples, the switching device adopts a load sharing mode, and after the second management module 1221 takes over the first switching module 1111, the management method further includes: when the first sub-board 112 is not pulled out from the first baseboard 111 within the target time length, the second management module 1221 stops managing the first switching module 1111, and the first management module 1121 takes over the first switching module 1111. Thus, the burden of the second management module 1221 is reduced.

Exemplarily, when the second management module 1221 does not receive the indication message sent by the first detection module 1112 to instruct the first sub-board 112 to be unplugged within the target time length, the second management module 1221 stops managing the first switching module 1111 and notifies the first management module 1121 to take over the first switching module 1111.

In other examples, as shown in FIG16 , the switching device adopts the master-slave mode. Then, even if the first sub-board 112 is not unplugged from the first baseboard 111 within the target time, the first switching module 1111 and the second switching module 1211 can still be managed simultaneously by the second management module 1221 without having to switch back to management by the first management module 1121.

In addition, as shown in FIG. 16 , when the switching device adopts the active/standby mode, the removal and insertion of the first sub-board 112 will not trigger the switching of the management subject of the first switching module 1111 .

It should be noted that the first switching module 1111 and the second switching module 1211 may also be replaced by other service processing modules, such as a message identification and analysis module and a clock module. Then the first switching module 1111 and the second switching module 1211 may also be expanded into a first service processing module and a second service processing module.

The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
