<p>A system and method for fast and reliable failure notification and accelerated switchover for path protection in a communications network of nodes interconnected by communications links is described. A method of path protection includes establishing plural working paths through the nodes. For each working path, an associated protection path is assigned. Upon a failure event, working paths that include the failed link are switched to their respective protection paths. The working and protection paths can include links on different networks having different media. At each node, linked lists for protection path activation, working path deactivation and path preemption are implemented upon a failure event.</p> |
