Abstract:
1. A method of establishing a restoration cycle for an arc on a mesh network, the method comprising the steps of: determining a set of possible restoration cycles for the arc on the mesh network; and selecting at least one restoration cycle from the set of possible restoration cycles based on capacities of arcs on the restoration cycles and flows on the restoration cycles; wherein the step of selecting at least one restoration cycle comprises determining a penalty cost associated with each of the possible restoration cycles, and choosing one of said possible restoration cycles with the lowest penalty cost; wherein the step of determining the penalty cost on the restoration cycle comprises determining the maximum available spare capacity for flow restoration for a particular arc on the restoration cycle; and wherein the step of determining the maximum available spare capacity for flow restoration on the particular arc on the restoration cycle comprises determining the maximum available spare capacity for flow restoration without interference on the particular arc, and determining the maximum available spare capacity for flow restoration with interference on the particular arc.
