Abstract
A method of load balancing zero-bandwidth Traffic Engineering Label Switching Paths (0-bw TE LSPs) in a communication network having a plurality of network nodes and a plurality of network links connecting the nodes. The method may be implemented in a centralized Path Computation Element (PCE) or in an ingress router. Each equal cost path from a source node to a destination node is identified from network topology information. A probability of selecting each equal cost shortest path is determined using an iterative Global Load balancing Algorithm (GLA) and each 0-bw TE LSP is provisioned with a specific probability such that the 0-bw TE LSPs are uniformly distributed over all network links.
