The high capacity provided by packet-switched networks is supporting the proliferation of bandwidth intensive multimedia applications which require multicasting capability. As a consequence a mixed traffic scenario where both unicast and multicast demands compete for the same shared resources, is the one more likely to be found within the current transport networks. On today's traffic-engineered networks such traffic travels through logical data paths setting up by constrained-based routing schemes provided by a control plane. In this paper, the authors have devised a novel constraint-based routing scheme to forward unicast and multicast traffic envisioning a system resource consumption outstanding performance.
