24、计主要针对局域网通讯而开发设计的，采用的是 C/S 构架， 类似飞鸽传书系统， 来实现聊天、文 件传输功能 ，并借助一些网络通讯组件，成功的实现了在局域网上的即时通讯。 本论文的目标是设计一个类似飞鸽传输的局域网通信软件， 并分析它在其领域的优势。本设计以 C 编写，能在 windows 2000/net/xp 等环境下运行。 设计 共分为五大模块，分别是： 首先， 介绍选题背景及意义和 国内外研究现状 ； 其次，介绍 TCP/IP 点对点协议技术 ， C/S 架构和 SOCKET 网络编程技术； 再次， 对当前局域网文件传输进行需求分析并提出解决方案； 然后， 根据解决方案对 系统进行设计；

25、 最后， 对工作计划统计 以及 分析系统进行测试并得到测试结果。 关键词 ： 聊天 ； 传输 ； socket； 飞鸽传书 ； C/S 结构 evaluation of scientif ic developm ent .
