Colin Perkins : Standards Contributions

Standards Contributions

I'm an active participant in the Internet Engineering Task Force (IETF), working on standards related to real-time networked multimedia. My current focus is RTP-related standards, in particular the use of explicit congestion notification with RTP, and real-time conferencing in web browsers. I was previously co-chair of the IETF's Audio/Video Transport (AVT) and Multiparty Multimedia Session Control (MMUSIC) working groups. I serve on the IETF Transport Area Directorate, and have also contributed to 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 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.
