Standards Contributions

IETF logo

I'm an active participant in the Internet Engineering Task Force (IETF), working on standards relating to real-time networked multimedia, including RTP, SDP, and WebRTC. I co-chair the RTP Media Congestion Avoidance Techniques working group (2016-), and previously co-chaired the Audio/Video Transport (1998-2008) and Multiparty Multimedia Session Control (2000-2007) working groups. I was a member of the Transport Area Directorate (2006-2015) and I'm a member of the Transport Area Review Team (2015-).

I have also contributed to MPEG-4 Systems in the Moving Picture Experts Group of the International Standards Organisation.

RTP: Audio and Video for the Internet

I'm author of RTP: Audio and Video for the Internet (Addison-Wesley, 2003). This book describes protocols and algorithms for real-time multimedia over IP networks, combining standards and research experience to give a practical guide for those implementing telephony, conferencing and streaming media applications.
