摘　　要：作为一种新的组播模型,特定源组播受到学术界越来越多地关注。它解决了传统IP组播组地址冲突、缺乏访问控制等问题,适于单源组播的应用。仿真实验是一种经济有效的网络技术研究方法。NS-2是目前应用较为广泛的网络仿真平台,支持各种网络协议仿真,但是并不支持特定源组播。为此,分析了使用NS-2进行IP组播模拟的实现原理,通过扩展NS-2实现SSM协议的仿真实验。模拟结果显示该仿真实现与SSM的规范相一致。As a new multicast model, source specific multicast draws more and more attentions. It solves the problems of the traditional IP multicast model, such as confliction of group address, lack of access control and is suitable to single source multicast application. Simulation is an effective and economical way to network research. NS-2 is a widely used network simulation platform, which supports many network protocols. However, SSM is not supported by NS-2. The principle oflP multicast simulation is analysed using NS-2, and SSM simulation is implemented by extending NS-2. Simulation results show that the implementation is consistent with S SM specification.
