Abstract

Method for performing a failure analysis of a communication network comprising links and nodes supporting transmission of service demands. The method comprises: selecting a failure combination affecting the links and/or the nodes; determining one or more broken service demands and one or more broken links affected by the failure combination; computing a respective restoration path for each broken service demand by excluding the broken links; determining whether at least two broken service demands have respective restoration paths that share a network resource over a conflicting link; and, in the affirmative: associating the shared network resource to one of the at least two service demands; removing, from the broken service demands, this service demand and the service demands whose restoration paths do not share any network resource; adding the conflicting link to the broken links; and repeating the above operations until a termination condition is fulfilled.
