Description/Abstract

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.
