Abstract
A method of routing lower multiplex level demands in a telecommunications network including a plurality of interconnected nodes to form higher multiplex level demand-routes. The method defines an initial lower multiplex level demand-route for each pair of nodes of the network. The initial lower multiplex level demand-route carries all lower multiplex level demands originating or terminating at a node of the pair. The method then splits the demand of each initial lower multiplex level demand-route between an express demand and an overflow demand and routes express demands in higher multiplex level express routes. The method patches the overflow demands into higher multiplex level routes according to a predetermined patching policy.
