Providing rich data collaboration services in conferencing system is vital to the success of SIP-based communication system. It not only presents design and implementation challenges, but also gives an opportunity to develop rich and innovative collaboration services conveniently to provide users with novel communication experience. In this paper we present an extended data collaboration mechanism for XCON conferencing system over IP network. It includes uniform media description, media negotiation and media delivery processes. The mechanism adopts the extended SDP and offer/answer model as media description and negotiation mechanism. And it uses RTP/RTCP and extended MSRP as the media transport control protocols respectively for audio/video and various TCP-based data collaboration applications. In this paper, the design principle and concrete implementation details is presented and analyzed in detail. We have developed a prototype implementation to prove our architecture’s feasibility and scalability.
