文档介绍：飞鸽传书软件的设计与测试
摘要
网络通讯在当今已经不算新鲜事物,上的服务器,这就给那些具有大规模内部网络的用户造成了许多问题,如浪费网络资源、遭遇到网络攻击、传播的病毒、破坏防御系统等等。由于互连网上的网络通讯工具给企业内部信息交流带来了不便,所以为了方便内部网络的用户之间的沟通,需要开发一个基于局域网的信息收发系统的即时通讯工具,实现在内部网络中进行信息的交流。本课题设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 /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;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。

Design and Implementation IP Messenger Based on LAN
Abstract
munication already do not calculate the new things now, but the munication all need to be support by the server on the , this make these user have the large-scale work who many problems, such as work resources, be attacked work, dissemination virus, destruction defense system and so on. Because the munication facilities on the munication brought inconveniently for the enterprise, in order to facilitate munication work user's, needs to develop one based on the local of instant message work information receiving and dispatching system instant message facilities, realizes carries on the information work the exchange. This topic design mainly aims at the local munication to develop the design, uses is the C/S skeleton,like IP Messenger, for chat and files transmission.
LAN against the text chat, documents and folders transmission, the design of a fake IP Messenger of LAN software, and analyze it in their areas of advantage. The design is developed by C program it can make in vironment of windows /xp of topic selection, in the environment The design altogether divides into five big modules, respectively is: First, introduction selected topic background and significance and domestic and foreign research present situation; Second, introduces the TCP/IP point to point protocol technology; C/S construction technique and work programming technology; Third, carries on the demand of the current local work file tra
