Abstract
A control system for a communication network stores a plurality of fault recovery plans that are respectively associated with a plurality of links. The control system processes a first control signal from the communication network indicating that one of the links has a fault, and in response, identifies one of the fault recovery plans that is associated with the one link having the fault and implements the one fault recovery plan. The control system receives a second control signal from the communication network indicating network information, and in response, recalculates the fault recovery plans. The recalculated fault recovery plans implement link-based fault recovery, sub-path based fault recovery, and path-based fault recovery. The recalculated fault recovery plans group links constituents into groups by QoS requirements and assign the groups to back-up routes based on the QoS requirements and the performance of the back-up routes.
