As shown in Figure 3, the network architecture includes multiple network devices mentioned above: a main device, a backup device, and a peripheral device. When the main device and the backup device are heterogeneous, the main device and the backup device cannot establish a stack for communication, which will cause business interruption and cause bad experience and losses to users.

In this embodiment, a method for replacing a heterogeneous stacking device running on the above network device or network architecture is provided. FIG. 4 is a flow chart of the method for replacing a heterogeneous stacking device according to an embodiment of the present invention. As shown in FIG. 4 , the process includes the following steps:

In step S402 of this embodiment, establishing a communication link between the primary device and the first device includes:

Port parameters are set for the primary device and the first device.

In step S402 of this embodiment, the active device on the network device and the first device perform port parameter setting, including:

The master device sets the following parameters according to the received heterogeneous device replacement command: converts the Spanning Tree Protocol STP state of the first port of the master device switching chip to a forwarding state; adds the first port of the master device switching chip and the second port of the master device switching chip to the same local area network; sets the data transmission rate of the first port of the master device switching chip to the maximum rate that the first port of the master device switching chip can reach; the first device sets the following parameters according to the received message: converts the STP state of the first port of the switching chip of the first device to a forwarding state; adds the first port of the first device switching chip and the second port of the first device to the same local area network; sets the data transmission rate of the first port of the first device switching chip to the maximum rate that the first port of the first device switching chip can reach.

In this embodiment, when the data synchronization fails, the method further includes: the master device maintains the device state as the master device state, and re-synchronizes the data after the first port of the master device and the first port of the first device are converted from a closed state to an open state.

In an exemplary embodiment, the data synchronization failure includes one of the following scenarios: the network cable on the qx port is loose, and the replacement of the first device is suspended.

Therefore, the problem in the related art that when the stacked device needs to replace the heterogeneous device, the heterogeneous devices cannot form a stacking mode, thereby failing to ensure that the service flow is not interrupted and the heterogeneous device cannot be smoothly replaced can be solved, and the problem of service interruption caused by the replacement of heterogeneous devices can be avoided.

Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as a read-only memory/random access memory (ROM/RAM), a magnetic disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

It should be noted that the above modules can be implemented by software or hardware. For the latter, it can be implemented in the following ways, but not limited to: the above modules are all located in the same processor; or the above modules are located in different processors in any combination.

To facilitate the understanding of the technical solution provided by the present invention, a detailed description will be given below in conjunction with embodiments of specific scenarios.

The embodiment of the present invention provides a method and apparatus for implementing heterogeneous stacking device replacement, which can be applied to a plurality of heterogeneous device replacement processes.

The replacement method includes: first, multiplexing the network management channel on the device panel, the network management channel includes but is not limited to the qx port (i.e., gateway interface), standby port, optical cascade port, and WIFI module, and connecting the network management channels of the two devices with network cables and optical fibers, or using WIFI modules to achieve wireless transmission. Secondly, a heterogeneous device replacement command is issued to the main device, and the link is opened by setting the corresponding port vlan, stp, rate and other parameters, and the original network management channel is converted into a main and standby communication link, and the communication data of the original main and standby stacking ports is diverted to the new communication link; the data stream is sent between the main and standby heterogeneous devices, and the data stream is first sent from the switching unit of each device to the network management channel on the panel, and then forwarded to the network management channel on the other device panel, and then to the corresponding switching unit, thereby realizing communication between heterogeneous devices. This method overcomes the problem that the service must be interrupted during the replacement of heterogeneous devices in the prior art.

The following is a detailed description of the method for implementing heterogeneous stacking device replacement based on the network architecture of FIG3 . As shown in FIG6 , the method includes the following process:

Step S601: unplug the original standby device in FIG3 , and the main device and the peripheral device communicate normally at this time;

Step S602: insert a new standby device with a heterogeneous switching chip, and enable the network management channel between the new standby device and the main device. At this time, the two devices cannot establish a stack or communicate with each other. The new standby device needs to close the connection link with the peripheral device to prevent the peripheral device from identifying the two main controllers and affecting the business. The new standby device is functionally equivalent to the first device in the above embodiment.

Step S603: Send a heterogeneous device replacement command, such as mix-mpu enable, to the primary device;

Step S604: the master device sets the STP state of the port connecting the switch chip and the network management channel to the forwarding state (forwarding);

Step S605: The master device sets the VLAN of the port connected to the switch chip and the network management channel, adds the port and the port of the switch chip connected to the CPU to the same VLAN, forwards the data with the VLAN when entering the switch chip, forwards it to the designated port, and strips the VLAN when leaving the switch chip port;

Step S606: The master device sets the rate of the port connecting the network management channel and the switch chip to the maximum rate that the port can reach, and transmits and receives at the maximum flow rate.

Step S607: The device with the heterogeneous switching chip determines based on the received message sent by the main device that if the other end is a heterogeneous switching chip, the network management channel setting is turned on by default, which is the same as steps S604-S606, to achieve indirect communication between the two devices.

Step S608: The two devices synchronize data via the new primary and backup communication link;

The specific traffic forwarding path is as follows: the CPU of the active device sends a synchronous data stream, which is forwarded to the switching unit of the active device, forwarded to the network management port of the active device through the switching chip, and then to the network management port of the opposite device (new standby device), to the switching unit of the opposite end, and finally sent to its CPU to achieve data synchronization between the active and standby devices;

Step S609: When data synchronization is completed, the main device is directly unplugged, and the newly inserted device will quickly switch to the main device and become the main device; at the same time, the links between each peripheral device and the main device are opened;

Step S610: insert another new device. The two devices are isomorphic devices. The new device still uses stacking communication, and the entire system returns to normal.

The present invention is further described in detail below using embodiments in specific scenarios in conjunction with the accompanying drawings:

Example 1

When replacing heterogeneous devices of a router, the qx port on the device panel is used for communication. As shown in FIG3 , it is assumed that device 1 is the main device and device 2 is the backup device. Device 1 is functionally equivalent to the main device in the above embodiment. The port of the qx port connected to the switching chip is port a (not shown in the figure). Specifically, as shown in FIG7 , the replacement process of heterogeneous devices includes the following steps:

Step S701: unplug device 2;

Step S702: insert a heterogeneous switching chip device into the slot where device 2 is located, named device 3, and connect the qx ports of device 1 and device 3 with a network cable. By default, the port connected to the peripheral device is closed in device 3; device 3 is functionally equivalent to the first device in the above embodiment.

Step S703: Send a heterogeneous switch chip upgrade command mix-mpu enable to device 1;

Step S704: after receiving the heterogeneous replacement command, device 1 sets the STP state of port a to forwarding;

Step S705: Device 1 sets the VLAN of port a, that is, port a and port b connected to the CPU are added to the same VLAN. When data enters the switch chip from port b, it is marked with the corresponding VLAN, forwarded to port a, and then stripped of the VLAN after exiting port a.

Step S706: Device 1 sets the rate of port a to send and receive at the maximum flow rate;

Step S707: Device 3 and device 1 perform data synchronization through the qx port. The specific data flow forwarding path is: the CPU of device 1 sends the synchronization data flow, and the data flow then enters the switching unit of device 1. The switching unit of device 1 forwards the data flow from port b to port a, and then to the qx port, and then forwards it to the qx port corresponding to device 3, and then enters the switching unit. The switching unit of device 3 forwards the data flow to the CPU of device 3, thereby completing the data synchronization of device 1 to device 3;

Step S708: After the data synchronization between device 1 and device 3 is completed, device 1 is unplugged. At this time, device 3 finds that the master device 1 is offline and it is a backup device, so it identifies itself as the master device and opens the link with the peripheral device;

Step S709: another new device is inserted in the place of the original device 1, named as device 4; device 3 and device 4 are isomorphic devices and can be stacked at this time; device 4 is functionally equivalent to the second device in the above embodiment.

Through the above steps, service traffic is guaranteed not to be interrupted when heterogeneous network devices are replaced.

Example 2

Based on the normal heterogeneous device replacement in Example 1, when an abnormal situation occurs, such as the network cable of the qx port is loose or the heterogeneous device replacement is suspended, the heterogeneous device replacement process is shown in FIG8, and further includes the following steps:

Assume that device 1 is the active device, device 3 is the heterogeneous standby device, and the port connected to the switch chip by the qx port is port a.

Step S801: Device 1 and device 3 are synchronizing data via the qx port;

Step S802: The network cable on the qx port is loose or the heterogeneous device 3 is suspended for replacement;

Step S803: Device 1 and device 3 both find that the physical state of port a becomes down, and data synchronization fails;

Specifically, device 3 and device 1 monitor the state change of port a and find that the port state changes from up to down, then modify the stp state of port a to block, delete the vlan of port a, and restore the port rate to the original port rate;

Step S804: after the synchronization fails, device 1 remains in the master device state to ensure normal service traffic; at this time, a network cable is inserted or a heterogeneous device 3 is inserted, port a is changed from down to up, and device 1 and device 3 will match the corresponding settings and restart data synchronization; in this embodiment, restarting data synchronization means that data is synchronized from the beginning;

Step S805: After the data synchronization between device 1 and device 3 is completed, device 1 is unplugged. At this time, device 3 finds that the main device 1 is offline and it is a backup device, so it identifies itself as the main device and opens a link channel with the peripheral device;

Step S806: another new device is inserted in the place of the original device 1, named device 4; device 3 and device 4 are isomorphic devices and can be stacked.

Through the above steps, service traffic is guaranteed not to be interrupted when heterogeneous network devices are replaced.

Example 3

When replacing heterogeneous router devices, the optical port on the device panel can also be used for communication, as shown in Figure 3. Assume that device 1 is the main device and device 2 is the backup device. The port of the optical cascade port connected to the switching chip is port a (not marked in the figure).

FIG. 9 is a flow chart of heterogeneous device replacement for optical port communication according to an embodiment of the present invention. As shown in FIG. 9 , the flow includes the following steps:

Step S901: unplug device 2;

Step S902: insert a heterogeneous switch chip device into the slot where device 2 is located, named device 3, and connect the optical ports of device 1 and device 3 with optical modules and optical fibers. By default, the port connected to the peripheral device is closed in device 3.

Step S903: Send a heterogeneous switch chip upgrade command mix-mpu enable to device 1;

Step S904: after receiving the heterogeneous replacement command, device 1 sets the STP state of port a to forwarding;

Step S905: Device 1 sets the VLAN of port a, that is, port a and port b connected to the CPU are added to the same VLAN. When data enters the switch chip from port b, it is marked with the corresponding VLAN, forwarded to port a, and then stripped of the VLAN after exiting port a.

Step S906: Device 1 sets the rate of port a to send and receive at the maximum flow rate;

Step S907: Device 3 performs data synchronization with device 1 via the optical port.

Step S908: After the data synchronization between device 1 and device 3 is completed, device 1 is unplugged. At this time, device 3 finds that the master device 1 is offline and it is a backup device, so it identifies itself as the master device and opens the link with the peripheral device;

Step S909: another new device is inserted in the place of the original device 1, named device 4; device 3 and device 4 are isomorphic devices and can be stacked at this time;

Through the above steps, service traffic is guaranteed not to be interrupted when heterogeneous network devices are replaced.

Example 4

When replacing a router heterogeneous device, data stream synchronization with the heterogeneous device can also be achieved through wireless WIFI, as shown in Figure 10. Specifically, the process of implementing heterogeneous device replacement based on wireless WIFI (i.e., the wireless module in Figure 10) is shown in Figure 11, and the process includes the following steps:

Step S1101: unplug device 2;

Step S1102: insert a heterogeneous switch chip device into the slot where device 2 is located, named device 3, and device 3 closes the port connected to the peripheral device by default;

Step S1103: Send a heterogeneous switch chip upgrade command mix-mpu enable to device 1;

Step S1104: after receiving the heterogeneous replacement command, device 1 sets the stp state of port a to forwarding;

Step S1105: Device 1 sets the VLAN of port a, that is, port a and port b connected to the CPU are added to the same VLAN. When data enters the switch chip from port b, it is marked with the corresponding VLAN, forwarded to port a, and then stripped of the VLAN after exiting port a;

Step S1106: Device 1 sets the rate of port a to send and receive at the maximum flow rate;

Step S1107: Turn on the wireless WIFI module transceiver function on the panels of device 1 and device 3, so that device 1 and device 3 can be interconnected to form a wireless link. After the data leaves the switching unit, it is sent and received via the wireless link for synchronization;

Step S1108: After the data synchronization between device 1 and device 3 is completed, device 1 is unplugged. At this time, device 3 finds that the master device 1 is offline and it is a backup device, so it identifies itself as the master device and opens the link with the peripheral device;

Step S1109: another new device is inserted in the place of the original device 1, named device 4; device 3 and device 4 are isomorphic devices and can be stacked at this time.

Through the above steps, service traffic is guaranteed not to be interrupted when heterogeneous network devices are replaced.

Assume that the original devices are named device 1, device 2, and device 3, and the replaced devices are named device 11, device 12, and device 13. Specifically, the method for replacing multiple heterogeneous router devices based on optical port communication is shown in FIG13, and the method includes the following steps:

Step S1301: unplug device 2;

Step S1302: insert the heterogeneous switch chip device 12 into the slot where the device 2 is located, and connect the optical ports of the device 1 and the device 12 with an optical module and an optical fiber;

Step S1303: Send a heterogeneous switch chip upgrade command mix-mpu enable to device 1;

Step S1304: after receiving the heterogeneous replacement command, device 1 sets the STP state of port a to forwarding;

Step S1305: Device 1 sets the VLAN of port a, adds port a and port b connected to the CPU to the same VLAN, and adds the corresponding VLAN to the data when it enters the switch chip from port b, forwards it to port a, and then strips the VLAN after exiting port a;

Step S1306: Device 1 sets the rate of port a to send and receive at the maximum flow rate;
