计算机网络协议及其算法对于初学者来说非常抽象和复杂,目前构建实际的物理网络进行演示教学由于成本和复杂性等原因而显得不切实际,而将应用于网络研究领域的仿真软件NS-2用于计算机网络课堂教学,以TCP协议的滑动窗口和慢启动算法在NS-2中的模拟过程为例,给出NS-2进行网络模拟的一般流程,通过通信协议的动画演示和Trace文件的分析,能使学生更容易、更深刻地理解网络协议及其算法的实现机制和网络通信的复杂行为,最后提出了NS-2在网络课堂教学中的2种实施方案.

Computer network protocol and its algorithm are abstract and complex for the beginners.At present,because of cost and complexity,it＇s impractical to build practical physics network to demonstrating teaching.But by using simulator NS-2,which is applied in the field of net research,into the computer network teaching,by taking the slide window of TCP protocol and slow start-up algorithm as an example,give general procedure of NS-2 doing net simulate,by motion picture demonstration of communication protocol and analysis of document Trace make students understand more easily and comprehensively the realizing mechanism and the complex behavior of net protocol and the algorithm,and at last,put forward two resolutions of application of NS-2 in network class teaching.
