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
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.
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.
