| 摘 要： | PIM-SM（Protocol Independent Multicast-Sparse Mode）协议是目前Internet首选的域内组播路由协议。与其他PIM协议相比,其RPT向SPT切换的机制可以有效地减少网络延迟,降低RP的负载。NS2是面向对象的离散事件仿真器,它能够有效地对各种网络拓扑和数据传输进行仿真。本文利用NS2对RPT向SPT切换的过程进行模拟,并详细分析得到的仿真数据。仿真结果证明了RPT向SPT切换的优越性。

| Abstract: | PIM-SM(Protocol Independent Multicast-Sparse Mode)is currently the preferred intra-domain multicast routing protocol.Comparing with other PIM protocol,the switching from shared tree to the shortest path tree can effectively reduce the network delay and the load of RP.NS2 is an object-oriented simulator based on discrete event.It can availably simulate network topology and network data transmission.This article is to simulate the process of switching from RPT to SPT with NS2 and analyze the simulated data in... |
