| 摘 要： | 网络技术和多媒体技术的发展使得未来的Internet对具有QoS(Quality of Service)需求的多播应用的支持变得更加迫切．为了解决现有QoS多播路由协议消息复杂度高、寻路成功率低以及连接建立时间比较长等问题，作者提出了一种新的QoS多播约束路由协议MRPQoS(Multicast Routing Protocol with QoS constraints)．它完全分布式运行，将局部搜索与全局搜索、单分支搜索与多分支搜索有机地结合在一起，较好地解决了上述问题．仿真结果证明：MRPQoS较其它协议更适合于网络状态变化比较频繁的环境以及实时多媒体应用．

| Abstract: | It becomes very urgent to support multicast applications with quality of service (QoS) requirements in the future Internet with the development of network and multimedia technology. In order to solve problems such as high message overhead?low success ratio and long connection setup time in present QoS multicast protocols, a new multicast routing protocol with QoS constraints (MRPQoS) is proposed in this paper. It could run absolutely distributed and solve the problems successfully by integration with local search and global search?single-branch search and multi-branch search. It is proved by the simulation result that MRPQoS is better than other protocols and is fitter for the network situations with the status changed frequently and the real-time multimedia applications. |
