Chen Dong-lang · Computer and Information Technology · 2006
The Session Initiation Protocol is the session controlling protocol of application layer of NGN(Next Generation Network).JAIN SIP,developed by SUN Company.,is the java-standard interface to a sip signaling stack for implementing SIP application.This paper present a framework of multimedia conference system user agent based on the architecture and implementation mechanism of JAIN SIP,analyzed the function of each layers which include the architecture of JAIN SIP,the command signaling of user agent(joining conference,adding conference,deleting conference etc),processing of multimedia information etc.Developing SIP-based applications with JAIN SIP will improve the development efficiency and the applications will gain high reliability and portability.
