Abstract
A maximum-flow based route precomputation algorithm includes at least a route generation phase and a route selection phase, and determines one or more routes between at least a given pair of nodes in a network. In the route generation phase, a maximum-flow algorithm is applied to a first set of information characterizing links between the given pair of nodes in the network. The output of the maximum-flow algorithm is utilizable to generate a second set of information characterizing corresponding admissible flows. In the route selection phase, one or more routes are determined based on the second set of information using, for example, a shortest widest path (SWP) algorithm. The route generation and route selection phases may be repeated for each of a plurality of node pairs of the network.
