Standards Contributions

IETF logo

I'm a long-time participant in the Internet Engineering Task Force (IETF). I develop transport protocol and signalling standards, with a focus on real-time networked multimedia. I also work on transport services and APIs for the post-Sockets network, the implications of QUIC on applications and network operations, and how best to specify network protocols.

I'm co-chair of the RTP Media Congestion Avoidance Techniques working group, 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 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 transport of real-time multimedia over IP networks. It combines standards and research experience to explain the basics of RTP-based telephony, conferencing and streaming media applications.
