The Design & Implementation Of An Enterprise Instant Messaging System Based On XMPP

In recent years, with the rapid development of technology, instant messaging systems have improved the efficiency of messages exchanging in our daily life and business work. And XMPP has the most rapidly developed in instant messaging protocols. With widespread use of instant messaging technology, the combine of business requirement and enterprise requirement become more and more important.XMPP is a kind of standardization protocol, which defines the grammar formats of each functional module without specific realizations. This makes systems based on XMPP can exchange message conveniently. Besides, with the help of JSF, the extended protocols of XMPP is rapid development, which improve the advantages like openness,expansibility,security and Platform independence of XMPP.The thesis includes the following content:(1) Analysis and comparison of popular instant messaging protocols. A summary description about relevant knowledge and the detail process of XMPP and extended protocols of it. Take further understanding of the content,history and development trend.(2) With the comparison between systems used in Individual users and systems used in enterprise users, make a in-depth analysis solution of sorts of problems which is found in enterprise process.(3) Realized the functions that were demanded by the systems through combining with open source package Gloox of protocol in accordance with the principles of system design.The thesis focused on building enterprise-class instant messaging systems architecture which was suitable for small enterprise environment by realizing open source protocol XMPP.Practices proved that the framework of the integration was powerful and low coupling.The framework of the integration enhanced the system's maintainability and scalability, which achieved the goals of instant messaging system.
