局域网飞鸽传书软件的设计与实现 摘 要 网络通讯在当今已经不算新鲜事物，但大多数网络通讯都需要借助Internet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内部网络的用户之间的沟通内部网络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；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 Design and Implementation IP Messenger Based on LAN Abstract The network communication already do not calculate the new things now, but the majority network communication all need to be support by the server on the Internet, this make these user have the large-scale internal network who many problems, such as waste network resources, be attacked by network, dissemination virus, destruction defense system and so on. Because the interconnection network communication facilities on the interior communication brought inconveniently for the enterprise, in order to facilitate internal communication between network users, needs to develop one based on the local of instant message area network information receiving and dispatching system instant message facilities, realizes carries on the information which network the exchange. This topic design mainly aims at the local area network communication 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 the cnvironment of windows 2000/net/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 sockt network programming technology; Third, carries on the demand of the current local area network file transfer to ana
