If the user configures the port sharing to other LRx through the command line, the CLI module in LR0 first synchronizes the port sharing information to the DRM in the SC through the MIM and DRM_A modules through the MIM and DRM_A modules, and simultaneously writes the local port ownership information to the library; Then DRM synchronizes the relevant information of the shared port to each LRx through multicast or other message mechanisms. After each LRx receives it, it judges if it belongs to its own message based on the LR identification ID and other information carried in the message, and then writes the shared port resource to the library. , Synchronize the MIM module and other related processing, and perform subsequent management, including creation, maintenance, etc., and finally present the shared port information to the users under the LRx.

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

The example of the present invention defines a port sharing method in a virtual network, and the main interaction processes are: system port resource management process, shared port verification process, shared port allocation process, and shared port redistribution process.

Optionally, the embodiment of the present invention provides a shared port management process, which includes the following steps:

Shared port management includes the current port management mode of the system, the management mode after the shared port is allocated, and the synchronization to the interface management and presented to the user through the command line, network management or other interface, as shown in Figure 5, this embodiment provides a Sharing the port management mechanism, the specific steps are as follows:

S501: In the virtual network router environment, DRM obtains the current physical port resource information and physical connection information of the system through resource reporting or other methods. The system defaults that all ports belong to LR0. The resource ownership information is written to the database and passed through the logical router module ( Hereinafter referred to as LRM) Collect the physical location information of the single board running on LR of LR0, and then synchronize the port resource information to DRM_A in LR0 through multicast or other message mechanisms;

Wherein, the port resource information of the DRM synchronization DRM_A includes: physical slot information to which the port belongs and related attributes, etc.;

Wherein, the DRM runs on the system main control management single board, and manages all resource information of the system;

Wherein, the DRM_A runs as a proxy module of the DRM on the line card to which each LR includes LR0 and LRx, and performs port resource information exchange with the DRM;

Wherein, after DRM_A under the LR0 receives the port resource information of the DRM, it writes the port information to the resource library, and further synchronizes it to the interface management module through MIM, and finally presents it to the user through a command line or other means;

S502: LR0 manages the shared or non-shared information of all ports, and at the same time maintains its own newly-created sub-interfaces or virtual sub-interfaces;

Wherein, the shared port can be shared to multiple LRs, including LR0 or LRx;

Among them, LR0 can see all the ports that are shared, and new sub-interfaces or virtual sub-interfaces under the current LR0, or other types of sub-interfaces;

Among them, LR0 can manage and maintain the information of all ports, including but not limited to whether it is shared or exclusive, shared LRs list information, and other related information.

S503: LRx manages and maintains its own newly-created sub-interfaces or virtual sub-interfaces;

Among them, LRx can see the shared port that has been shared to itself;

Among them, LRx can manage and maintain the shared port and the newly created sub-interface or virtual sub-interface.

When the shared port is allocated, the port must first be checked and verified. After the conditions are met, the port sharing allocation process is performed. As shown in Figure 6, this embodiment provides a shared port filtering and checking mechanism. The specific steps are as follows:

S601: Check whether the port and the board to which the port belongs are exclusively occupied by other LRs. If they are exclusively occupied by other LRs, they cannot be shared;

Wherein, the port verification is performed in the DRM module;

Wherein, the port or the single board to which the port belongs is exclusively occupied by other single boards, and the port or the single board to which the port belongs needs to be reclaimed. After reclaiming, the port sharing can be allocated;

S602: Check the number of LRs allocated to the shared port, if the maximum LR sharing the same port limit is exceeded, sharing is not allowed;

Wherein, the maximum LR sharing the same port limit is comprehensively set according to system performance, user usage, and other factors;

S603: The port verification is passed, and the port sharing allocation processing is performed.

Optionally, the embodiment of the present invention provides a shared port allocation and recycling process, which includes the following steps:

The port allocation process requires LR0 to perform write library management, and then synchronize to other LRs. LR0 performs unified management of port resources, as shown in Figure 7. The specific steps are as follows:

S701: After the port sharing allocation instruction is issued, DRM_A in LP0 writes the configuration library according to the command, and at the same time notifies DRM for further processing;

S702: DRM first performs shared port verification, and the verification passes. DRM first writes the LR and other related information of the shared port to the port resource allocation library, and at the same time advertises port ownership related information to other LRs through multicast or other message mechanisms;

S703: After DRM_A in LR0 receives the updated port attribution information sent by DRM, it updates the port attribution information database, and records information such as LR related to port sharing;

S704: After DRM_A in LRx receives the updated port ownership information sent by DRM, it determines if it is the information of this LR, updates the port ownership information database, and at the same time notifies MIM through multicast or other messages, and finally presents it through command prompts or other methods To the user, so that the user can see the port information under the current LR;

Wherein, the shared port recovery process is similar to the allocation process. After receiving the port attribution information of DRM, LR0 or LRx updates the corresponding port information attribution database. LRx also informs MIM and presents it to MIM through command line or other methods. user.

Optionally, the embodiment of the present invention provides a shared port redistribution process, as shown in FIG. 8, which mainly includes the following steps:

After the port is shared, the port and the board to which it belongs can no longer be allocated to other LRs for resource exclusive use. If the port or the board to which the port belongs needs to be allocated to other LRs for exclusive use, the shared port needs to be recycled, as shown in the figure As shown in 8, the specific steps are as follows:

S801: If the port or the board on which the port is located needs to be allocated to other LRs for exclusive use, first check which LRs the port has been shared with, and if it has been allocated for sharing, first reclaim the port;

S802: After the shared port is reclaimed, the port or its own board can be allocated to other LRs for exclusive use;

Wherein, the shared port recovery, specifically, after the port shared recovery instruction is issued, DRM_A in LP0 writes the configuration database according to the command, updates the port attribution information database, and synchronizes to DRM; further, DRM is notified through synchronization or other message mechanisms LRx deletes the port information distribution library and has completed the recovery of the shared port.
