This paper addresses multicast routing in 40Gb/s traffic in heterogeneous optical networks. The multicast routing of multi-rate traffic (MRMT) problem is informally defined as the process of finding the best routing which maximizes the total bandwidth utilization in the network, for a given set of sessions, and a given WDM and TDM equipment budget. In our model, a multicast connection is realized by constructing a multicast tree. The whole process is divided into two steps. Numerical results demonstrate our approach utilizes network resources more efficiently, as compared to the approach based on shortest path algorithm.
