Abstract
A system and method for the detection of permanent virtual circuit failures in a communication network determines and classifies failures based upon physical or logical criteria. Upon detection of a physical failure or a logical failure the virtual circuit backup logic will establish an alternate path in order to selectively reroute information avoiding the failed primary path. Once the primary path is again available, the logic of the present invention will restore the communication from the alternate path to the primary path. The virtual circuit backup logic will selectively provide an alternate path for communication traffic on a per data link connection identifier (DLCI) basis, thus enabling a single link to be backed up over multiple links.
