应用网络仿真器研究Internet协议

Research of the Internet Protocol Based on Network Simulator

研究分析当前网络通信研究与设计领域应用广泛的网络仿真器,讨论开放源代码的网络仿真器ns2的内部原理与实现,应用ns2对Internet协议稳定性问题进行了仿真研究,结果表明在网络延迟增加甚至链路带宽增大后协议将不稳定.

Some network simulators that have been widely applied in the area of network research and design are studied and compared. The architecture principle and implementation of the network simulator ns2 are analyzed. Using ns2, the stability of Internet protocol is researched. The results show that the protocol becomes unstable when delay or capacity increases.
