Proceedings of the 6th Annual AccessGrid Retreat, Ann Arbor, MI, USA, May 2006.
In this extended abstract we present the UltraGrid system, the current state of the art in high definition conferencing. UltraGrid was the first system to support gigabit rate high definition interactive video conferencing on commodity systems and networks. We review the design and implementation of UltraGrid, discuss experimental results and deployment, and conclude with our vision of the future of conferencing systems.
