摘　　要：采用网络模拟仿真方法,选用NS2仿真软件模拟IP网络运行。编程实现四种典型的网络拓扑结构:总线型、星型、环型、网型,选取网络传输中的数据包延时、延时抖动、丢包率以及吞吐量等关键性能指标为实验采集对象。通过大量的仿真实验数据分析不同拓扑类型对IP网络性能产生的不同影响。In this paper, network simulation method is mainly adopted. In order to simulate IP network operation, NS2 simulation software is applied. Four typical network topology structures： Bus, Star, Ring, mesh are achieved by programming. We select some key performance indicators of network transmission as experimental collection objects such as packet delay, delay jitter, packet loss rate and so on. The experimental results show that different topology types have different effects on IP network performance.
