ABSTRACT:
A two step method for determining restoration cycles for a mesh network includes generating a set of possible restoration cycles, and selecting a subset of low-cost restoration cycles on the network. The cost of a restoration cycle may be based, in part, on the availability of capacity on the link to restore traffic with and/or without interference, and network policy. Enabling the restoration cycles to be determined based on the bandwidth capacity of the restoring link, the flows carried by the other link, and other network policy considerations enables embodiments of the invention to account for traffic class, priority, and other traffic considerations when selecting restoration cycles on the network. Identifying arcs on the network with relatively high cost restoration cycles allows portions of the network to be targeted for increased capacity.
