This paper proposed the design model and implementing method of virtual Computer Networks lab which is based on NS2. In this lab, the client part is implemented with java applet, NS2 is used as computing platform, Nam is used as the tool for displaying in the client, and java RMI is used for communication between the server and the client. The virtual experiment equipments are implemented with java Bean. The server that uses NS2 as computing platform has powerful simulating capability. The Web-based Virtual Computer Networks lab provides platform between users and NS2, which makes users leave out the trouble of studying NS2. Users can use it to do network simulation experiment and deeply understand the complex behavior in computer networks.

虚拟实验室随着计算机技术的高速发展而发展。以前，虚拟实验室的发布，通常是以随书光盘的方式，而现在是采用网络，特别是因特网(Internet)，一种全新的方式。这种方式具有信息传递的快速性，无时间地点限制(At Any Time and Any Place)、丰富的友好图形操作见面(GUI)等优点，这些是目前其它任何方式所无法比拟的。利用计算机网络技术作为它新的传播实现工具，大大方便了用户。虚拟实验室的应用必将广泛的流行起来。
本文研究了控制系统网络虚拟实验室的设计与实现问题。取得了以下主要研究结果：
1．提出了虚拟实验室结构—一个基于浏览器—Web服务器(B／S，Browser／Server)和客户／服务器(C／S，Client／Server)相合并的全新结构。
2．基于B—S结构的虚拟实验室网站设计与实现。
3．基于C—S结构的客户端程序和服务器程序的设计与实现。
4．计算机仿真软件—Matlab／Simulink中的模型文件及相关算法的设计与实现。
5．两个实例的具体实现。
本文还简略介绍了构建控制系统网络虚拟实验室所用到的相关技术。这些技术包括了网页设计技术、java程序设计语言、数据库接口、网络原理及Matlab／Simulink等。
最后对全文的工作进行了总结，对网络虚拟实验室的进一步的发展与研究方向作了展望。
