Research Interests The Internet Real-Time Laboratory designs, analyzes and prototypes next-generation "radio", "TV" and "telephone" networks. We develop protocols for resource reservation (BGRP, RNAP, YESSIR), call setup (SIP), media-on-demand (RTSP), and data transport (RTP). We are investigating architectures for wireless networks, service creation for Internet telephony and pricing for scalable Internet QOS.
