Abstract

A node in a communication network selects between equal cost shortest paths (ECSPs) using split tiebreakers. The node advertises multiple system identifiers (IDs) for that node, and each system ID is associated with a different set of traffic IDs that distinguish different virtual networks in the network. The node receives sets of system IDs for each of the other nodes in the network. After constructing a plurality of different ECSPs between two nodes the node selects one of the ECSPs for each traffic ID used between the two nodes. For a traffic ID, the node constructs path IDs for each of the ECSPs using one system ID of each node in the path that is associated with that traffic ID. Because of the configuration of the system IDs and the traffic IDs in the network traffic affected by a failure will be distributed across a plurality of surviving ECSPs.
