A conference control protocol for highly interactive video-conferencing
نویسندگان
چکیده
Video-conferencing is an efficient tool for distributed collaboration. With the wider availability of broadband wide area networks such as the Internet2, we can expect an increasing demand for video-conferences conducting over broadband wide area networks. In this paper, we present a conference control protocol for a highly interactive conference paradigm and its collaboration environment. In such collaboration environment, a fixed number of channels (three) for multimedia traffic as well as a common control channel are used. We propose a conference control protocol that uses a three-channel rotation floor control scheme to coordinate access to the shared media channels and avoid race conditions. Experimental results as well as the implementation in a research video-conferencing system for wide area networks show that the proposed protocol can effectively eliminate race conditions while maintaining the scalability and reliability .
