| 摘 要： | 现有基于分支路由器的组播路由机制能有效减少转发状态并提高可扩展性,但这些组播路由机制的加入时延较长,且对分支路由器失效的适应性较差。针对上述问题,提出一种新型的基于分支路由器的快速分支组播(fast branch multicast,FBM)路由机制。FBM结合了已有分支组播路由机制的优点,并通过为接收者预先建立临时转发状态而加快组播加入过程。在NS2中对FBM和其他相关协议进行了实现。仿真和理论分析结果表明,FBM不但可以加快组播加入过程,而且能对组播转发进行有效地控制,以快速适应分支路由器的失效。

| Abstract: | Current BR(branching-router)-based methods can reduce multicast state and improve the scalability,but they suffer from long join latency,and can not adapt BR fails quickly.To solve the problem above,we proposed a novel BR-based multicast routing protocol fast branch multicast(FBM)in this paper.This scheme took the advantages of the current BR-based multicast management.And through pre-establishing temporary forwarding states,FBM speed up the multicast join process.In this paper,we implemented FBM and other ... |
