Abstract
Systems and methods include receiving a list of prioritized optical restoration paths for each of a plurality of failures in a multi-layer network, wherein each list of prioritized optical restoration paths for a corresponding failure of the plurality of failures is determined based on modeling impact of the given failure on a higher layer, relative to an optical layer; and, responsive to a failure of the plurality of failures, utilizing a corresponding list of prioritized optical restoration paths for the failure to restore services in the optical layer. The modeling impact can include determining new routes and link utilization in the higher layer, prioritizing links in the higher layer, and utilizing the prioritized links to determine the list of prioritized optical restoration paths, for the given failure. The higher layer can be an Internet Protocol (IP) layer.
