Design And Implementation Of Multi-Party Communication Platform Based On XMPP PubSub

With the rapid development of Internet,people’s demands on multi-party communications applications are more and more intense,which promote multi-party communications system to be more open, distributed, collaborative and dynamic. In the traditional multi-communication system,it’s difficult to achieve all kinds of multi-application cases in a single platform, but the emergence of multi-party communication system based on XMPP protocol and publish subscribe model makes multi-party communication into a stage of real unified platform.Depending on the application requirements, Paper first proposes a new multi-communication system model and discusses the choices of the relevant protocols and technologies. Then extends the publish subscribe protocol and multi-Jingle protocol, so as to meet the needs of multi-transfer model; Finally, the multi-party communications platforms was designed and implemented. The innovation of the system is the use of the XMPP protocol to enable the scalability; while taking advantage of multimedia middleware for a variety of types of communications applications (such as data, signaling, media) to provide a unified multi-communication interface, making the multi-party communication really unified.
