Problems solved by technology

Nodes or links in the bearer network often carry multiple leased line services. When a node or link in the network fails, the services it carries will be affected at the same time. If rerouting calculations are performed on these services one by one, the routing calculation will increase. The burden of modules leads to long service recovery time

Abstract

The invention discloses a rerouting method, device and storage medium, wherein the method includes: judging whether there are multiple shared risk service paths belonging to the same shared risk service group in the service path based on the shared risk service division rule; , then divide the shared risk business group among multiple business paths, and divide the shared risk business path into the shared risk business group to which it belongs; determine the business group rerouting path of the shared risk business group. Multiple shared risk service paths in the risk service group share the service group rerouting path. The rerouting method, device and storage medium of the present invention can utilize the division of shared risk service groups to realize "multi-service sharing of one routing calculation result" during prefabricated rerouting calculation, which can reduce repeated routing calculations and effectively reduce calculation overhead. Improve the processing efficiency of path calculation and achieve the purpose of fast rerouting.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a rerouting method, device and storage medium. Background technique [0002] Rerouting is a service recovery method, which calculates the path used for service recovery, and when a fault occurs, the newly established path is used to transmit the service. Nodes or links in the bearer network often carry multiple private line services. When a node or link in the network fails, the services it carries will be affected at the same time. If rerouting calculations are performed on these services one by one, the routing calculation will increase. The burden of the module leads to a long service recovery time. Therefore, how to realize fast rerouting recovery of multiple services is an important issue in the process of network operation and maintenance. Contents of the invention [0003] In view of this, a technical problem to be solved by the present invention ...
