Abstract
A method implemented in a node of a multi-protocol label switching (MPLS) network for improved load distribution, including determining a first set of one or more shortest paths between each MPLS node pair, selecting at least a first shortest path by applying the common algorithm tie-breaking process, calculating a link utilization value for each link of the MPLS network, determining a second set of one or more shortest paths between each MPLS node pair, generating a path utilization value for each shortest path in the second set of shortest paths based on link utilization values corresponding to each shortest path, and selecting a second shortest path from the second set of shortest paths on the basis of said path utilization value, whereby the selection of the second subsets in light of path utilization minimizes the standard deviation of load distribution across the entire MPLS network.
