YIN Guo-fu(Department of Computer Science.Weinan Teachers College,Weinan 714000,China)  
The essay analyses the principle,the architecture and the main functions of the simulation software of NS_2,aiming at how to use NS_2 in experimental teaching of computer network.That is,building a virtual network enviroment to assist comptuter network teaching by exploting NS_2;analysing comprehensively the result of the simulation software by means of various methods of data analysis;having a statistical analysis of the track data of the network by Gnuplot construction software.It is demonstrated that the system of the simulation software,which plays an important role in experimental teaching of computer network,provides for students the platform of operating,observing and analysing,as well as stimulate students to develop exploratory learning activities.
