摘　　要：讨论一种适应于研究QoS多播路由的网络模型。在网络环境及不确定参数条件下,提出了一种在网络规模、可行性方面为Internet、移动网络和其他高性能网络基于Tabu搜索的QoS多播路由优化算法(TQM-RA)。仿真实验结果表明,TQMRA在网络环境及不确定参数条件下能够优化网络资源。This paper discusses the QoS muhicast routing problem, and describes a network model for researching therouting problem. It presents Tabu - search based QoS muhicast routing algorithm （ TQMRA ） , a QoS muhicast routing policy for Internet , mobile network or other high - performance networks , that , based on Tabusearch algorithm , can provide QoS - sensitive paths in a scalable and flexible way , in the network environment with uncertain parameters. The TQMRA can also optimize the network resources and converge to the optimal or near-optimal solution, even for the network environment with uncertain parameters. Simulation results show that TQMRA is a good approach to QoS multicast routing decision.
