网络仿真在教学中的应用研究

kesearch on：Application of NS2 Network Simulation Tools in the Teaching

网络仿真技术是一种通过建立网络设备、链路和协议模型，并模拟网络流量的传输，从而获取网络设计或优化所需要的网络性能数据的仿真技术。该文使用主流网络仿真工具NS2对教学实验网络建立了仿真模型．讨论了网络拓扑结构和仿真参数的选取方法。仿真结果表明丢包率随着网络数目的增加显著提高。

The network simulation technology is a simulation technology for setting up models of network devices, links and protocols, and simulating network traffic transmissions, gaining the required network performance data in network design or optimization. Authors use the mainstream network simulation tool NS2 in teaching network, set up a simulation model to discuss the network topology and the method of simulation parameters selection. Simulation results indicate the packet loss rate statistics on a variety number of monitor nodes.
