Abstract :
Taking the characteristics of difficulty on exact measurement and complete expression of NGI (next generation Internet) into account, a flexible QoS multicast routing algorithm based on DE (differential evolution) is presented with introduction of principle of fuzzy mathematics. The corresponding model and its mathematical description are introduced. Under inaccurate information of QoS parameters and users´ flexible QoS constraints, the proposed algorithm tries to find the multicast tree with maximum reliability degree and user´s QoS satisfaction degree. Simulation results have shown that the proposed algorithm is both feasible and effective
