In order to build an integrated collaboration system over heterogeneous collaboration technologies, we propose a Global Multimedia Collaboration System (Global-MMCS) based on XGSP A/V Web-Services framework. This system can integrate multiple A/V services, and support various collaboration clients and communities. Now the prototype is being developed and deployed across many universities in USA and China.

In this paper we present a scalable, integrated and service-oriented collaboration system, namely Global Multimedia Collaboration System, based on the XGSP collaboration framework and NaradaBrokering messaging middleware. This system can provide videoconferencing services to heterogeneous endpoints such as H.323, SIP, Access Grid, RealPlayer as well as cellular phone. This paper discusses the design principle, system architecture and implementation in detail. The extensive performance measurement has been made to evaluate the scalability of the system.

Global Multimedia Collaboration System (Global-MMCS), a scalable, robust and service-oriented collaboration system, can bridge H.323, SIP, Access Grid clients and 2.5G/3G cellular phones in audiovisual collaborations. The H.323 gateway in Global-MMCS enables H.323 terminals to interact with other clients, and provides them the complete H.323 conference control services.
