Abstract:

The NGI Multicast Applications and Architecture project has developed innovative technologies and standards that greatly increase the quality and scalability of IP-based multicast teleconferencing and real-time motion imagery distribution systems. These scalability enhancements fall into two categories 1 improved support for large-scale distributed meetings 2 improved support for distribution of high-definition video. In particular, we have demonstrated a prototype Digital Amphitheater supporting virtual meetings with hundreds of simultaneous teleconferenced participants, and a prototype system for delivery of gigabit-rate High Definition video over commodity IP networks. These capabilities are significantly beyond those available commercially, and leverage the advanced network infrastructure developed as part of the DARPA Next Generation Internet research program.
