为了实现课程实验教学的网络化工程，网络虚拟实验平台已成为我们的迫切需求。这次毕业设计的目的主要是为了检查使学生综合运用以前所学知识的能力，开发一个多功能的网络虚拟实验台软件。教师管理模块主要实现C/S模式系统的服务器管理功能，包括响应客户端的连接请求、用户注册、登陆、登陆通知、显示在线用户列表、用户退出通知、对系统数据库文件管理、服务器根据路由算法分配最佳节点给客户端进行P2P通信、客户端能随时存取数据等。这次课题分为2个模块：服务器模块和客户端模块。其中客户端模块又包括了网络模块、数据分析模块。服务器模块分为网络模块、数据库接口模块、数据分析模块。网络模块负责提供最基本的数据传输功能，数据库接口模块负责提供对数据的查询、添加、删除功能，数据分析模块解析接收到的数据，并生成需要回复的信息。服务器的数据分析模块还要根据客户端应用层的指令，生成与指令相应的发送信息。网络虚拟实验平台可以更好的帮助学生掌握实验技巧。

In order to realize network engineering for experiment teaching later, the virtual experiment platform has become our urgent demand. The purpose of the thesis is mainly to develop a multifunctional virtual experiment software for inspecting the students’ ability of comprehensive utilization of the knowledge.  The teacher administration module mainly realizes the C/S pattern system server management function, including the response customer end connection request, the user registration ,lands, lands the notice, demonstrated the on-line user tabulates, the user withdrawal notice, to the system database file management, the server carries on the P2P correspondence, the customer end according to the route algorithm assignment best pitch point for the customer end can deposit and withdraw the data as necessary and so on . The thesis is divided into 2 modules: Server module and customer module. Customer module includes the network module and the data analysis module. The server module is divided into the network module, the database interface module, and the data analysis module. The network module provides the basic data transmission function. The database interface module provides the functions to inquire, add, and delete data. While, the data analysis module analysis the received data, and produce the reply information. The server data analysis module also needs to produce the relative sending information with the instruction, according to the customer application instructions. The network virtual experiment platform can help student grasp the experiment skill in a better way.

 

Key words: Virtual experiment platform; C/S mode; best pitch point; P2P technology; route algorithm
