分布式即时通信系统的设计与实现

Design and Implementation of Distributed Instant Messaging System

随着互联网技术的不断发展,即时通信软件的出现大大影响人们之间的交流方式,随着即时通信功能的越来越强大,人们也越来越依赖于即时通信软软件。但是随着用户量的增大,单机系统已经较难支持庞大的用户群,因此将系统进行横向的扩展,即从单机模式转换成分布式模式已经成为即时通信系统的主流趋势。对分布式即时通信系统的研究背景和意义进行阐述,重点阐述系统的详细设计,以及各个模块的功能,并展示已实现的分布式即时通信系统的主要功能。

With the continuous development of Internet technology, instant communication software has greatly affected the communication between the people, with the instant communication function more and more powerful, more and more people rely on instant communication soft- ware. But with the increase of the number of users, the stand-alone system has been difficult to support the huge user base, so for the horizontal expansion of the system, from the stand-alone mode into a distributed mode has become the mainstream trend of instant messaging system. Describes the research background and significance of the distributed instant messaging system, and then foeuses on the detailed design of the system, as well as the function of each module. Finally, presents the main functions of the distributed instant messenger system.
