  • Constraint-based route selection using biased cost
    Patent number: 6363319
    Abstract: The present invention is a method and apparatus for selecting a route for a flow from a plurality of network paths connecting a source to a destination. The method comprises: (a) determining cumulative costs for a plurality of candidate paths from the network paths using a cost bias which is dynamically calculated based on at least one of a flow attribute and a path attribute; and (b) selecting an optimal path having a minimum of the cumulative costs. The optimal path corresponds to the selected route.
