Abstract
Communication network connection failure protection methods and systems are disclosed. Control information is communicated in a communication network, and causes network elements of the communication network to establish connection monitoring for respective segments of the network connection. Connection monitoring information which is communicated on the segments allows failures such as loss of continuity to be detected and reported. Responsive to an indication of a failure on a segment, the segment on which the failure occurred is identified, and the network connection can be rerouted around that segment.
