QoS Multicast Routing Algorithm Based on Immune Genetic Method in NGN

This paper proposes the network model which supports QoS multicast. With the optimization of existing QoS multicast routing algorithms, this paper proposes the QoS multicast routing algorithm based on immune genetic method in NGN. The simulation results indicate that the algorithm has high convergence speed and reliability, and can meets the demand of QoS multicast in NGN well.
