METHOD AND APPARATUS FOR NODE REALIGNMENT IN A TELECOMMUNICATIONS NETWORK

摘要

A method of realigning a node in a label switched network comprising a plurality of nodes and a node with a processor, a memory, and a network interface, for carrying out the method. The method includes periodically maintaining backup path status information for the node., restarting the node, and re-establishing label switched paths with the plurality of nodes using the backup status information. Communication with adjacent nodes is carried out in order to reconcile the path status information with respective path status information in the adjacent nodes in order to establish node realignment preferably judged against a threshold value for path reliability.

1. A method of realigning a node in a label switched network comprising a plurality of nodes, the method comprising:
periodically maintaining backup path status information for the node; in response to restarting of the node, re-establishing label switched paths with the plurality nodes using the backup status information; and communicating with an adjacent node in order to establish a path reliability value for each path recorded in the backup status information using a reliability value from the adjacent node, in order to establish node realignment.
