Abstract
In a telecommunications network provisioned with a path based distributed restoration algorithm, upon the detection of a failure in a link, each of the custodial nodes of the failed link sends a special message to the respective end nodes. These end nodes communicate with each other over a communications network independent of the telecommunications network and, in turn, inform the custodial nodes of the identity of the other custodial nodes. By providing each custodial node with the knowledge that its adjacent node is its opposing custodial node, any functional link that cross-connects the custodial nodes is deemed to be of poor quality and, therefore, should not be used as a part of an alternate path for rerouting the disrupted traffic, unless no other alternate path could be found.
