PIM-SM注册报文发送的分布式实现

Distributed Implementation of PIM-SM Register Message Sending

针对指定路由器向汇聚点路由器注册过程中,主控生成报文数量过多对路由器造成负担太大的问题,提出分布式注册报文发送的实现方案,其主要包括理论分析与仿真测试。结果证明该方法减轻了主控的处理负担,缩短了数据包在路由器里的平均处理时间,减少了主控与底层信息交互的次数。

This paper proposes a distributed register message forwarding way to cope with the problem when Designated Router（DR） send register message to Rendezvous Point（PR）, which may result in too many register packets on the controller plane of the router. Theoretical analysis and simulated data results show that the method lightens the controller plane＇s execution load dramatically, shortens the equal execution time of multicast packets in the router, and reduces the interactive time between controller plane and data plane.
