Abstract:

 Internet2 Commons is a next generation application framework that encourages deployment of tools for large scale distributed collaborative environment for the research and education community in U.S. The general architecture of design and managing large-scale, distributed videoconference collaborative environment was proposed. Key techniques of H 323-based videoconference system in Internet2 Commons were studied. Ordinary videoconference applications and special videoconference-based applications developed on Internet2 were also introduced. Migration policies of videoconference application from IPv4 network to IPv6 testbed were analyzed and Conclusions were given.

Key words: H.323 protocols, videoconference, collaborative environment, IPv6 technology
