Abstract

Upper layer 3 routing in conjunction with self-healing lower layer networks is more informed by the addition of reachability costs determined in the lower layer. Maintenance changes on the self-healing network are monitored. A change causes revision of reachability costs. The revised costs are communicated by lower layer logic to upper layer logic.
