Abstract: An integrated QoS multicast routing algorithm in IP/DWDM optical Internet was discussed. Given multicast request and users QoS requirements, an algorithm was proposed on genetic algorithm basis to address the issue routing and wavelength assignment in an integrated manner, construct a flexible QoS multicast tree and assign wavelengths to the tree, based on the wavelength graph method. Thus, both the cost of QoS multicast tree and users satisfaction of QoS approach to optimum. The proposed algorithm also considers load balancing in IP/DWDM optical Internet. Simulation results show that the proposed algorithm is feasible and effective.
