基于Java即时聊天系统的设计与实现

摘要:计算机网络技术高速发展的今天，即时通讯方式日益受到人们的青睐。即时聊天工具在实现传输视频与音频信息，使协作成员可以远距离进行直观、真实的视音交流的同时，利用多媒体的技术，它还可以帮助使用者对工作中各种信息进行处理。

本课题研究的是支持内部网络交流的系统——网络即时通讯系统。该系统使用Java语言进行编程。系统采用CS结构模式，支持局域网和Internet。该系统采用软件工程的瀑布模型进行开发，分别讨论了系统的需求分析、概要设计、详细设计和编码、以及整个系统的运行和测试。 关键词：即时聊天；系统；Java；CS

Abstract: The rapid development of computer network technology today, more immediate means of communication by people of all ages. Real-time chat tool in achieving the transmission of video and audio information, so that members can collaborate remotely intuitive, real audio and visual communication at the same time, use of multimedia technology, it can also all kinds of information processing.

Study of this issue is to support the exchange of internal network systems - network instant messaging system. The system uses Java programming language. System uses the C S structure mode, support for LAN and Internet. The system uses the waterfall model of software development projects were discussed system requirements analysis, outline design, detailed design and coding, and run and test the whole system. Finally, the paper concluded.

Of course, the system there are some imperfections, and seek to study and work in the future be amended so that the system actually

used in a variety of network efficiency.
