Paper Abstract

High quality video conferencing is an efficient tool for interactive scientific collaboration in the research community, especially for researchers separated by substantial distance. With the wide deployment of broadband wide area IP networks such as the Internet2, there is an increasing demand for improved remote collaboration with these networks. In order to make the high quality video-conferencing toolkits for local high-speed networks available over wide area IP networks, issues that are usually insignificant on local area networks must be considered. To this end, we have developed called Adaptation Layer Translator (ALX) in order to address these issues and solve the problems associated with real-time video and audio transmission over wide area IP networks. A conference control protocol is developed to coordinate the participants in an ALX-based conference. The ALX is also designed to be able to adapt to heterogeneous network environments at different deployment sites.
