基于NS-3的计算机网络路由转发实验教学方案

Experiment teaching design of computer network routing and forwarding based on NS-3

为了保证“计算机网络”课程实验教学效果,文章以NS-3网络离散事件仿真模拟器为基础框架,通过搭建典型的路由转发网络实验,在NS-3平台上展示网络配置和路由转发过程。同时,设计和实现了六种基于不同路由端口选择条件的仿真实验,让学生更深入理解网络中数据包的路由转发过程,熟悉六种路由端口选择模式,理解数据包根据统计的不同网络行为特征选择路由转发端口。

In order to ensure the experiment teaching effect of"computer network"course,a typical routing and forwarding network experiment is designed to demonstrate the network configuration and the process of routing and forwarding based on the discrete event driven NS-3 network simulator.At the same time six simulation experiments based on different routing port selection conditions are designed and implemented to enable students to better understand the routing and forwarding packets in the network,be familiar with the six routing port selection modes,and understand that packets select forwarding ports according to different network behaviors.
