网络协议演示系统设计

Demo System Design of Network Protocol

伴随着人们对网络的依赖性的不断增强,引发一场网络技术的学习热潮。网络技术涉及到的知识和原理多,给网络技术学习造成了一定的困难。另一方面,在网络教学过程,使用实际物理设备进行实验和教学,会带来教学成本增加、设备维护困难等问题。本设计旨在运用当前比较热门计算机仿真技术,开发一个专门应用计算机网络教学的网络原理演示系统。一方面,利用面向对象[1]编程思想,建立计算机网络中基本设备(计算机、交换机、路由器,通信线路等)的虚拟类,大大节约了购买硬件设备的成本;另一方面,利用Windows窗体的图形界面和编程技术,对复杂而抽象的网络原理和信息处理传输过程进行可视化,以达到提高教学效率的目的。

Along with the dependence of people on the network's growing,social demand on the networking have become more sophisticated,it also set off a wave of network technology learning.Network technology knowledge and principles involved in many technological learning the network caused some difficulties.On the other hand,the teaching process in the network,using the actual physical equipment for experiments and teaching,the teaching will bring increased costs,equipment maintenance problems and other issues.This is designed to compare the use of current popular computer simulation technology to develop a specialized application of principles of computer networks,the network of teaching demonstration system.On the one hand,the use of object-oriented programming ideas,establish computer networks of basic equipment(computers,switches,routers,communication lines,etc.) a virtual class,significant savings in the purchase of hardware costs;the other hand,the use of Windows Forms Graphics interface and programming techniques,complex network of abstract principles and information processing transfer process visualization in order to achieve the purpose of improving teaching effectiveness.
