Research And Implementation Of The Web Instant Messaging Agent

Most of instant messaging systems require special client software, that makes users hard to install and maintain, but also is not conducive to web mashup. At present, it has been focused most to achieve web access to instant messaging system without client.This paper first discussed the basic principle of instant messaging, and analyzed XMPP protocol used by InstLink system with HTTP protocol in web. Then, the common web agent is studied. Moreover, a solution of the web instant messaging agent is proposed and illustrated from the perspective of requirement analysis, logical and interaction design.This paper also contributes to building prototype experiment environment-a test network that includes the InstLink server, the web instant messaging agent and user group. A series of tests are conducted to the agent. The experimental results indicate that the web access application mode has been achieved by the agent.
