Abstract:
In one embodiment, a method for supporting recovery from failure of a node in a network of nodes interconnected by links A set of two or more intermediate nodes (excluding the failed node) between an ingress point and an egress point is selected. Next, based on available bandwidth of the network, a non-zero fraction of the service level to route from the ingress point to each intermediate node is determined. Packets are then routed in two phases by: (1) determining one or more paths from the ingress point to each intermediate node for routing the corresponding fraction of the service level, and (2) determining one or more paths from each intermediate node to the egress point for routing the corresponding fraction of the service level.
