源特定聚集组播在NS2仿真平台的扩展

The analysis and design of internet course teaching system for operation system

本文对网络仿真工具NS2进行了研究,分析了NS2的扩展方法和组播路由实现机制。结合源特定聚集组播的原理,在NS2中增加新的AggSSM类用以支持源特定聚集组播的仿真,同时使用OTcl语言和C++语言对AggSSM类的数据结构,方法和操作进行了定义,完成了源特定聚集组播在NS2平台上的扩展。

In this paper,network simulation tool NS2 were studied,and NS2 extension methods and multicast routing implementation mechanism were analysed.Source Specific Multicast with the principle of aggregation,in the NS2 to add a new class of AggSSM gathered to support Source Specific Multicast simulation,using OTcl language and C ＋＋ language AggSSM class data structures,methods and operations are defined to complete the expansion of Source Specific Multicast gathered at the NS2 platform.
