In one embodiment, a method for supporting recovery from failure of a link in a network of nodes interconnected by links. An intermediate node between an ingress point and an egress point of the network is selected to minimize the sum of (i) a capacity constraint between the ingress point and the intermediate...http://www.google.com/patents/US7978594?utm_source=gb-gplus-sharePatent US7978594 - Efficient and robust routing of potentially-variable traffic with local restoration against link failures
