虚拟计算机网络组网平台的设计与实现*

组网实验对于学习计算机网络知识非常重要，但是由于网络结构的多样性和网络设备的昂贵价格，真实的组网实验环境通常很难获得。为了解决这一问题，提出了用软件模拟网环境的设想。为此对虚拟计算机网络组网平台进行了功能分析和系统结构设计。通过采用Form++提供的基础类库，搭建了组网平台的整体框架，并进一步融合VRML技术成功地将网络组网、软件配置和设备三维展示集成起来，最终实现虚拟计算机网络组网平台。该平台成功应用于本科计算机网络实验教学中，体现出了良好的实用价值。

Design and Implementation of Virtual Network Design Platform

The network experiment is important to the learning of computer network knowledge,but experimental environments are not always available because of the diversity of the network structures and expensive network devices.This paper proposes to use software to simulate the experimental environments to solve this problem. By the function analysis and system structure design of Virtual Network Design Platform(VNDP),we use the foundation class libraries of tool(Form ) and also VRML technology to implement the platform which integrate the network-design,software-configuration and 3D-display of devices.This platform has been proved useful and valuable in the computer network experiment for undergraduates.
