摘　　要：随着大量新型的多媒体在高性能网络、移动网络及Internet中的应用,满足QoS约束的多播路由协议越来越重要。针对目前多播路由协议无法同时满足可扩展性和高成功率,提出了一种新的以移动代理为基础的QoS多播路由协议(MA-QMR)。该方法允许多播协议在移动代理间实现并在代理所访问的每个结点得到动态应用。不同于单播路由,移动代理以并行和分布形式协作方式来构建多播树,同时使消息开销最小化并满足QoS要求。With the large number of new multimedia application in high-performance networks, mobile network and Internet, the QoS-aware multicast routing protocol is more and more important. Because few of them can achieve high success ratios while keeping good scalability, a new mobile agents based QoS multicast routing protocol （MAQMR） is described. This approach, first, allows the multicast protocol to be implemented within mobile agents and dynamically deployed at every node the agent is visiting. Second, independently ofunicast routing, mobile agents act in parallel and distributed fashion cooperate in order to construct the multicast tree while minimizing message overhead and satisfying QoS requirements.
