Algorithm for Dynamic Multicast Traffic Grooming in Optical Mesh Networks

Aiming at the problem of the huge bandwidth gap between low capacity requirement of an individual multicast connection and high capacity offered by a wavelength channel in current optical networks, a multicast traffic grooming algorithm based on the multicast traffic grooming model is proposed by grooming new multicast traffic onto the optical multicast trees which have been built, in order to improve network resource utilization efficiency and reduce multicast traffic blocking probability.Simulation results show that the network performance can be improved significantly by the algorithm.
