Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the technical defects in the prior art, the main idea of the technical scheme provided by the embodiment of the invention is as follows: on the basis of high-speed signals 4 × 25G, 12/10 × 10G and 1 × 100G between a switching chip and a data interface transceiver (PHY) (i.e., a system side) of a 100G switch service board, ports such as CXP, CFP2 SR10, CFP2LR4/ER4, N QSFP +, N SFP + and the like are supported between the data interface transceiver (PHY) and an optical module (i.e., a link side), so that a free network layout of the service board based on the ports is realized, and on the basis of not changing hardware equipment, dynamic allocation of 100G port capacity is realized through software.
The embodiment of the invention provides a port capacity allocation method. Fig. 1 is a flowchart of a port capacity allocation method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps (step S102-step S106):
step S102, receiving an indication message sent by a network management system and used for indicating the dynamic port configuration of a port of a service board card of a switch, wherein the indication message comprises destination port mode information of the port needing to be configured;
step S104, configuring the port into one or more virtual ports according to the type of the optical module supported by each port, wherein the one or more virtual ports conform to the mode information of the destination port;
step S106, distributing all the configured virtual ports to a plurality of virtual switches according to the service requirements of the users, so that the port capacity of the service board of the switch is redistributed through the virtual ports of the virtual switches.
In practical applications, there are many types of switch service boards, for example, 40G switch service boards and 100G switch service boards, and since the application of the current 100G switch service boards is relatively wide, embodiments of the present invention mainly perform capacity dynamic allocation on ports of optical modules of the 100G switch service boards, and compared with a traditional relatively single port capacity usage mode, the capacity usage mode can meet diversified capacity usage requirements of users.
In the embodiment of the present invention, the types of optical modules supported by each port may include: CXP 100G-SR12, CFP2/CFP4100G-SR10, CFP2/CFP4100G-LR4, or CFP2/CFP4100G-ER 4.
According to the types of the optical modules, the process of configuring the ports of the optical module in step S104 may be implemented as follows:
(1) in case the type of optical module supported by a port is CXP100GE-SR12, the port may be configured as SFP +12 × 10G SFI virtual port, QSFP +3 × 40G XLAUI virtual port, or 1 × 100G GAUI virtual port.
(2) In case the type of optical module supported by a port is CFP2/CFP4100G-SR10, the port may be configured as SFP +10 × 10G SFI virtual port, QSFP +2 × 40G XLAUI virtual port, or 1 × 100G GAUI virtual port.
(3) In the case that the type of the optical module supported by the port is CFP2/CFP4100G-LR4 or CFP2/CFP4100G-ER4, the port may be configured as a 1 × 100G GAUI virtual port.
In the embodiment of the present invention, the step S106 may be implemented by: all virtual ports are grouped according to service requirements based on a Virtual Logic Device (VLD) function, and each group of virtual ports is divided into virtual switches meeting the service requirements.
Preferably, before executing step S102, a port mapping relationship between a switching chip and a PHY in the switch service board and a signal attribute of the switching chip may be configured according to a service type of the switch service board; and initializing the exchange chip and the PHY according to the mapping relation and the signal attribute.
This is done to prepare the port splitting or merging process in the above-described modes (1), (2) and (3).
In practical application, the above embodiment may be applied to a scenario where a 100G switch traffic board accesses a plurality of types of optical modules and compatibly supports and virtualizes a plurality of port capacities, since CXP and CFP2 optical modules have encapsulation differences, ports and mapping relationships used by the traffic boards may be determined according to the type differences of the traffic boards, Serdes rates between a switch chip (MAC) and a physical interface transceiver (PHY) are set to be 4 × 25G, 12/10 × 10G, or 1 × 100G, then, according to corresponding CXP, CFP2 SR10, CFP2LR4/ER4, 10 × SFP + access characteristics between the physical interface transceiver and the optical modules, and physical access types, any port of the 100G traffic board is dynamically split and merged independently, according to the difference of the optical module characteristics, if the port accesses the CXP optical module, the port may be used as a 1 × 100G or 3 × 40G or 12 × 10G port, if the port is accessed to the CFP2 SR10 optical module, the port can be used as a 1X 100G or 2X 40G or 10X 10G port, and if the port is accessed to the CFP2LR4/ER4 optical module, the port can be used as a 100G port.
By combining port-based virtualization technology, the port capacity of the 100G switch board card can be subjected to various combined layouts, and the ports are freely divided into various virtualization switches, so that the dynamic setting of the port capacity of the 100G service board card is realized, and the flexible network deployment and management of the port capacity of the whole network structure can be realized through virtualization.
To facilitate understanding of the implementation process of the port capacity allocation method provided by the above embodiments, the following description is made in more detail with reference to the preferred embodiments and fig. 2 to 5.
PREFERRED EMBODIMENTS
The preferred embodiment is mainly described by using a 100G switch service board card for illustration. The external interface physical terminals include ports of several types, such as 100G CXP, 100G CFP/CFP2/CFP4, and the preferred embodiment can make the switch service board actual physical terminals compatible with different types of 100G optical modules, dynamically manage the port attribute as 1 × 100G/M × 40G/N × 10G, virtualize the ports into different switching devices, and flexibly allocate the port capacity to the network layout.
Fig. 2 is a schematic diagram of port link establishment according to an embodiment of the present invention, please refer to fig. 2 for easy understanding, and assuming that the external port of a single service board in fig. 2 is M CXP ports or N CFP2 ports, the high-speed Serdes of the switch chip MAC interfacing the physical interface transceiver chip PHY can be identified as 12/10 × 10G, 4 × 25G, 1 × 100G channels as the HOST side (i.e., system side) of the 100G link through the type attribute and the switch chip attribute of the service board, and the LINE side (i.e., LINE side) of the PHY chip is piggybacked with 10 × 10G cau, 4 × 28VSR, 3/2 × 40G XLAUI, and 10 × 10G SFI through dynamic port attribute management.
For the service boards of M CXP ports, the optical module to which each port is docked is CXP 100G-SR12, it may be dynamically set whether a single port is 100G or split into 3 40G ports or 12 10G ports through a network management system, and the M CXP100G ports may independently and dynamically allocate port capacities. When 1 CXP port is used as 1 100G port, other CXP100 ports are connected through MPO optical fibers, when 1 CXP port is split into 3 40G ports for use, other 3 40G QSP + ports are connected through MPO switching optical fibers, when 1 CXP port is split into 12 10G ports for use, other 12G SFP + ports are connected through MPO switching optical fibers for use, and the other M-1 CXP ports are similarly applicable to the application.
For the service board cards with N CFP2 ports, the optical module to which each port is connected is CFP2100G-SR10 or CFP 2100G-LR 4/ER4, a single port can be dynamically set to be 100G or split into 2 40G ports or 10G ports through a network management system, and a CFP2100G-SR10 optical module link adopts 10 × 10G, which can be dynamically split and combined. However, since the 100G-LR4/ER4 optical module link employs 4 × 25G, dynamic disassembly cannot be performed. When 1 CFP2 port is split into 2 40G ports or 10G ports, only the butting CFP 2100-2100G-SR 10 optical module can be normally used, 40G or 10G ports are respectively butted through MPO switching optical fibers, when 1 CFP2 port is used as 1 100G port, the CFP 2100-2100G-SR 10 or 100G-LR4/ER4 optical module can be butted, the characteristics of a physical interface transceiver and a switching chip are driven back through the acquisition of the type of the optical module, and the optical module automatically supports the use of different types of optical modules of CFP 2100G. The N CFP2100G ports can independently and dynamically allocate port capacities, and after the upper management device dynamically allocates port attributes, it needs to access optical modules of corresponding types in combination with the CFP2 characteristics.
In practical applications, a port access CXP optical module can be dynamically split into 12 × 10G ports, 3 × 40G ports or combined into 1 × 100G ports, a port access CFP2 SR12 optical module can be dynamically split into 10 × 10G ports, 2 × 40G ports or combined into 1 × 100G ports, and the CFP2LR4 and CFP2 ER4 are suitable for transmission of several hundred meters according to characteristics of optical module devices, and can only be used as 1 × 100G ports, where transmission distances of the ports of each type are as follows: the transmission distance of CXP 100G-SR12 is 100-800m, the transmission distance of 100G CFP2/CFP4-SR10 is 100-800m, the transmission distance of 100G CFP2/CFP4-LR4 is 10Km, and the transmission distance of 100G CFP2/CFP4-ER4 is 30 Km. Therefore, the service board card of the 100G switch is not limited to be used by a single 100GE, the diversified port transmission distance can meet the service requirements of users to a greater extent, and the dynamic allocation based on the ports can flexibly manage the external ports.
Fig. 3 is a schematic diagram of a logical structure implemented inside a port link according to an embodiment of the present invention, and as shown in fig. 3, the logical structure uses a bidirectional circular linked list as a port resource management pool of a driver layer, and a head node is a port general attribute resource, including basic information of a switch service board, a port mapping relationship, a Serdes rate, and port attributes inside a switch chip, and the like.
When the specific service board card type is identified, corresponding port universal attribute resources are loaded, port initialization of a switching chip (MAC) is carried out, and new nodes are added to a bidirectional linked list in combination with related initialization of a hooked data interface transceiver (PHY) and an optical module. And establishing a subsequent initial node according to the capacity distribution characteristic of the saved port operated at the previous time when the service board card is powered on, and correspondingly adding or deleting nodes by a bidirectional linked list in the logic structure when the network management system dynamically splits and merges the ports after the service board card is started.
For example, when all ports are started according to 100G, assuming that each switching chip (MAC) supports two 100G data links, the ports are established as a unit-0/port-1 fabric node and a unit-0/port-13 fabric node, and so on for more switching chip units. And when the service board is started, the port resource management pool is established. For example, for the CXP port operation, if the network management system dynamically splits the unit-0/port-1 into 12 10G ports, the unit-0/port-2 to unit-0/12 nodes and the filling related attribute values can be established by modifying the related attributes of the unit-0/port-1 structure and adding nodes from the unit-0/port-1 position. And if the 12 10G ports from unit-0/port-1 to unit-0/port-12 are dynamically merged, deleting the nodes from unit-0/port-2 to unit-0/12 from the bidirectional circular linked list, and modifying the related attributes of the unit-0/port-1 structure. If the unit-0/port-1 is dynamically split into 3 40G ports, the unit-0/port-5, unit-0/port-9 and filling related attribute values can be established by modifying the related attributes of the unit-0/port-1 structure and adding nodes from the position of the unit-0/port-1. The dynamic split merge operation is performed for unit-0/port-13, which is similar to unit-0/port-1.
Fig. 4A is a schematic diagram of an implementation process of port capacity layout of a 100G board card according to an embodiment of the present invention, as shown in fig. 4, when the 100G board card is started, a system may identify relevant characteristics of a switch service board card to determine whether a CXP service board card or a CFP2/4 service board card is supported, configure a port mapping relationship and a high-speed signal attribute of a switch chip in a case of determining the support, initialize a data interface transceiver (PHY) chip in an initialization process of the switch chip, and automatically manage a port state according to a stored port configuration in combination with an optical module type accessed by an external port.
Fig. 4B is a schematic diagram of a port capacity allocation process of a 100G board card according to an embodiment of the present invention, and as shown in fig. 4B, the process includes the following steps:
step S402, splitting or merging the ports;
step S404, setting a source port mode and a destination port mode, and recording a chip number and a port number to be operated;
step S406, creating a new chip port bitmap;
step S408, clearing the port rate, specifically clearing all the bandwidth setting information of each submodule in the port exit direction and the port related access data;
step S410, adjusting port configuration information, removing old port configuration and adding new port configuration;
step S412, setting port rate, specifically setting bandwidth of each submodule of the port in-out direction, wherein the port has message receiving and sending characteristics;
step S414, adjusting the drive of a data interface transceiver (PHY) so as to be compatible with different 100G optical modules;
step S416, finally updating the port resource management pool;
step S418, notify the port change of the related service module.
In the implementation process of the capacity layout shown in fig. 4A, if traffic boards of M CXP ports are identified, the ports can access the CXP 100G-SR12 optical module and can be switched in port modes such as 1 × 100G CAUI, 12 × 10G SFP + and 3 × 40G QSFP +, and all M ports can be dynamically and independently adjusted.
If the service boards of N CFP2 ports are identified, the ports can be accessed to CFP2100G-SR10 or CFP 2100G-LR 4/ER4 optical modules, the port configuration and the optical module access are independent, however, the round-trip port mode switching of 1 × 100G CAUI, 10 × 10G SFP + and 2 × 40G FP + can be performed only when CFP2100G-SR10 is satisfied, the CFP 2100G-LR 4/ER4 only supports 1 × 100G CAUI, and under the condition of such port mode setting, the switch data link port can normally work.
For example, the ports of the service board are CXP 100G-SR12 optical modules, the default is to start according to 100G when starting, if one of the ports is configured as 12 split 10G ports according to the stored ports, the system performs a port splitting action according to the source port mode being 100G CAUI and the destination port mode being 10G SFI, and according to the above operation steps, finally, 1 100G port is split into 12 10G ports, and the 12G ports are fed back to the upper network management system. In the operation process of the service board card, if a certain 12G ports need to be merged, under the condition that the normal work of other ports is not influenced, the system can perform port merging action according to the condition that the source port mode is 10G SFI and the destination port mode is 100G CAUI, the dynamic adjustment of 1 100G port and 3 40G ports is executed in the same manner, and the port conversion between M × 40G and N × 10G needs to be realized by merging into 100G ports and then splitting to realize corresponding port capacity replacement. The CFP2 service board is implemented similarly.
For the upper network management system, the port attribute based on a single port can be dynamically adjusted, VLD (very-low-density-loss) is carried out on the port, and the flexible port capacity allocation and port isolation functions are achieved.
