System and method for configuring permanent virtual circuit from end to end

Abstract

The system comprises: a database operation engine for getting and saving the information about the network; a adjacency-matrix building module for converting the network topology structure into the undirected graph in order to calculate the shortest path between the source end and the destination end; a route calculating module for calculating the shortest path between the source end and the destination end; a resources acquiring module for getting the VPI / VCI value of each port; a PVC building module for building the PVC in each network element; and a quit processing module for executing the roll-back operation for failure to build end-to-end PVC.

Description

technical field [0001] The invention relates to the network management technology, in particular to the PVC (Permanent Virtual Circuit) technology in the network management technology. Background technique [0002] The method for realizing the end-to-end PVC in the prior art is basically that the operator manually selects the route and establishes a series of PVCs to realize the end-to-end connection. Existing implementations have the following deficiencies: [0003] 1. The route manually selected by the user is hardly ideal in terms of effective bandwidth or the number and sequence of network elements experienced, and unreasonable routing leads to an unnecessary increase in the number of segmented PVCs. It not only wastes network resources but also increases the risk of failure. [0004] 2. Since the user needs to manually select the route and specify the available VPI (Virtual Path Identifier, virtual path identifier) ​​and / or VCI (virtual channel identifier, virtual cha...

Problems solved by technology

[0003] 1. The route manually selected by the user is hardly ideal in terms of effective bandwidth or the number and sequence of network elements experienced, and unreasonable routing leads to an unnecessary increase in the number of segmented PVCs. Not only wastes network resources but also increases the risk of failure

[0004] 2. Since the user needs to manually select the route and specify the available VPI (Virtual Path Identifier, virtual path identifier) ​​and / or VCI (virtual channel identifier, virtual channel identifier) ​​values ​​of the two ports of different network elements on the trunk line, this first requires Users know the VPI / VCI used by the trunk port and the available VPI / VCI range, which inevitably leads to a large workload, especially when the network is deployed, which will inevitably lead to a lot of work and increase the pressure on users; / VCI is manually specified by the user, which will inevitably cause confusion in the maintenance process in the future. The user must spend a lot of time to know which VPI / VCI has been used, and the used VPI / VCI is not logical

[0005] 3. The end-to-end PVC established using this method does not have protection capabilities. When any segmented PVC fails, the communication between the two endpoints will fail; when this happens, it will take a certain amount of time to locate the fault. , the user needs to send multiple man-machine commands to detect each segmented PVC one by one; and rebuilding the PVC after a fault is found requires the user to accurately understand the network environment and establish the required segmented PVCs one by one.

[0006] 4. When an end-to-end PVC is no longer needed and wants to delete the end-to-end PVC, the user needs to delete the segmented PVCs one by one, which will lead to wrong or missing deletions, making the deletion operation as cumbersome as the establishment operation. need careful operation
