Abstract

There is assigned at least one first cost for expanding at least one link to a circuit-switched network that is part of a hybrid network comprising the circuit switched network and a packet switched network. All paths in the packet switched network are represented with a virtual link. A cost is assigned to the virtual link. An integer programming problem is solved to determine a number of links to add to the network, the integer programming problem having as inputs a model of the hybrid network and a demand forecast matrix.
