Abstract
A method of on-line routing of permanent virtual circuits is disclosed. The method uses an exponential cost function based on the network state and virtual circuit parameters to determine paths for the virtual circuits without scaling. The method may also advantageously use information available when multiple virtual circuits are requested to determine paths for the virtual circuits. Additionally, the method allows the routing selection to be refined so that the total cost of routing all the virtual circuits is reduced.
