Abstract

The invention discloses a method and device for dynamic switching of rerouting services of a transmission network. The method includes: a network management analyzes a received device alarm command, determines an alarm point network element, analyzes and obtains a path-finding start point and a path-finding point for service failures. the end point of the path; the network management initiates a rerouting command to calculate the path between the start point of the path finding and the end point of the path finding to obtain a normal path; for the normal path obtained by calculation, delete the original faulty path on the device configuration, activate and download the configuration of the normal path to the device; after the configuration is downloaded successfully, replace the faulty path to restore service communication, reroute and replace the connection successfully, and complete the service switching. The normal path segment and normal network elements of the original path are reused during the pathfinding process. When the pathfinding start point and pathfinding end point are used for pathfinding, the number of network elements to be searched for pathfinding can be reduced, which helps to improve the pathfinding efficiency.

Description

technical field

[0001] The invention belongs to the field of service rerouting in telecommunication network management, and more particularly, relates to a method and device for dynamic switching of rerouting services in a transport network. Background technique

[0002] In optical networks, especially in intelligent optical networks (Intelligent Optical Network, abbreviated: ION), with the increase of network operation time and the increase of the number of connections established and deleted in the network, the use of resources is likely to be unreasonable, affecting network operations. At this time, it is necessary to adjust the routing of some existing connections in the network to optimize the use of network resources. In addition, in the process of network operation, network maintenance work may be required to adjust network resources, such as adding nodes or links. During the process of resource adjustment, some connections may be affected. Therefore, Affected connec...
