Abstract: A method for deriving a set of efficient path costs for a group of nodes comprising a source node and a plurality of destination nodes in a data communications networks, wherein the path costs for paths between nodes in the group are defined in the network and each path cost comprises a restrictive cost and an additive cost, comprises iteratively identifying the paths of higher bandwidth first and, when two or more paths of equal bandwidth are encountered, selecting the path having a lower transit delay associated therewith.
