摘要
计算机网络的运行行为是不可见的,为了能够实时了解网络的运行效能,网络仿真是可靠手段。采用先进的网络模拟工具NS2对端到端网络进行了模拟仿真以及多方面的性能测试,测试包括端到端延迟、抖动、丢包率以及网络吞吐量等参数。实现了网络模型的动态生成、数据传输的动画模拟、实时数据的计算以及运行结果呈现,给出了在NS2平台上执行仿真的原理和方法,并对仿真结果进行了具体的分析。
The operation of network is invisible, and for the real-time understanding of the network efficiency, network simulate is a positive means. With NS2, the professional Network Simulation tool, the end-to-end network is simulated, and various performances of the network are tested, including propagation delay, jitter, packet-loss ratio and throughput etc. This paper presents the dynamic generation of the network model and the parameter of network capability, gives the principle and method of simulation based on NS2, and analyzes specifically the simulation results.
