摘要：With the increasing demand of multimedia applications, efficient and effective support of quality of service (QoS) has become more and more essential. A multicast communication creates a distribution tree structure, on which a multicast source sends a single copy of data to a group of receivers instead of sending a separate copy of the data to each receiver as in a unicast communication. In this paper, we study the bandwidth, delay, delay jitter, and packet loss ratio constrained least-cost multicast routing problem which is known to be NP-complete, and present an adaptive genetic simulated annealing algorithm (AGSAA) to solve the QoS multicast routing problem. The simulation results show that this algorithm has fast convergence and excellent cost performance.
