摘要
即时通讯软件系统是当前一个热门应用系统,传统的即时通讯系统大致采用的都是C/S结构并且各自使用了不同的通讯协议,并且在将即时通讯扩展到音频、视频时需要重新定义相关协议。SIP协议是由IETF提出的一个VOIP的控制信令协议。提出了一个基于扩展SIP协议的即时通讯系统原型框架,并介绍了该框架在Linux环境下即时消息发送的实现。
The instant communication software system has been seen as one of the most popular application system in nowadays. Most of the tradition instant communication system refer to a C/S architechture,and use their own communication protocol respectively. Moreover, the communication protocol should be modified when audio and video communication is needed. In this paper,a prototype instant communication system is proposed. It is based on the extended SIP protocol. The implementation of instant messaging under Linux programming environment is described.
