C. Brailean from Packetvideo
President, Chief Executive Officer & Co-Founder
Bio
Dr. James Brailean is the President, CEO and Co-founder of PacketVideo, the
world's leading provider of carrier-grade infrastructure software that enables
mobile multimedia. Under Brailean's leadership, PacketVideo launched the world's
first commercial end-to-end wireless multimedia delivery platform in August
2000, and has since conducted trials with more than 45 wireless operators
globally, including NTT DoCoMo, Sprint PCS, SKTelecom, Swisscomm, T-Mobile, and
many others.
A scientist who led the development of the MPEG-4 standards for transmission
of video and audio over wireless networks, Brailean holds 16 key U.S. patents
that will power the next generation of multimedia content and communications.
From 1993 to 1998, Brailean served as the chairman of the Error Resilience Video
Compression Ad Hoc Group within MPEG-4.
Prior to co-founding PacketVideo in 1998, Brailean was a principal staff
engineer within Motorola Corporate Research and Development Laboratories in
Chicago where he managed the Advanced Video Algorithm Group. This group was
responsible for the design and development of advanced video compression and
imaging algorithms.
From 1985 to 1989, Brailean was a communication system engineer for Hughes
Aircraft, Space and Communications Group. He received his doctorate in
electrical engineering from Northwestern University. Brailean also holds a
master's of science degree in electrical engineering from the University of
Southern California and a bachelor's of science in electrical engineering from
the University of Michigan.

Abstract
In this talk, we focus on content delivery networks (CDNs) for
delivering streaming media to end-users on the internet. We look at critical
drivers of this technology and business, including considerations of cost,
performance, reliability, and scalability. We then delve into the architectural
challenges and tradeoffs in building a streaming CDN that is capable of
simultaneously delivering hundreds of thousands of high-quality streams to
end-users in a reliable fashion. As an illustration, we describe Akamai's
FreeFlowSM Streaming service that delivers live, simulive, and on-demand
streaming media to end-users in all the major formats. Akamai's delivery network
for web content, streaming media, and applications is a large, highly
fault-tolerant platform that comprises more than 13,000 servers within over
1,000 networks in 63 countries. In addition to addressing specific technological
challenges, we also outline potential research issues that emerge in the context
of streaming CDNs.

Mohammed
Ghanbari from University
of Essex
Professor
Bio
Mohammed (known Ali to friends) is a professor in the Department of
Electronic Systems Engineering with the main research interest in the areas of
Video Networking. He graduated from Aryamehr University of Technology, Tehran,
Iran with a BSc degree in Electrical Engineering in 1970 and MSc in
Telecommunications and PhD in Electronics from the University of Essex, England
in 1976 and 1979 respectively. After 10 years work in Radio and Television
broadcasting he started his academic career in 1986 as a Research Fellow working
on Video coding for Packet Networks. He was then appointed as a Lecturer at the
Department of Electronic Systems Engineering, University of Essex, in 1988 and
promoted to Senior Lecturer then Reader in 1993 and 1995 respectively. He was
appointed a personal chair in 1996.
He is best known for his pioneering work on two-layer video coding for ATM
networks, now is known as SNR scaleability in MPEG-2 video codecs. He has
registered for three international patents on various aspects of video
networking. and was the co-recipient of A.H. Reeves prize for the best paper
published in the 1995 proceedings of IEE in the theme of digital coding. He was
also a co-investigator of the European MOSAIC project studying the subjective
assessment of picture quality, which resulted to ITU-R Recommendation 500. He is
the co-author of Principles of Performance Engineering, book published by IEE
press in 1997, and the author of Video coding: an introduction to standard
codecs, book also published by IEE press in 1999.
He has been an organizing member of several international conferences and
workshops. He was the general chair of 1997 international workshop on Packet
Video and Guest Editor to 1997 IEEE Transactions on circuits and systems for
Video Technology, Special issue on Multimedia technology and applications.
Currently he is an Associate Editor to IEEE Transactions on Multimedia
(IEEE-T-MM) and represents University of Essex as one of the six academic
partners in the Virtual Centre of Excellence in Digital Broadcasting and
Multimedia. He is a Fellow of IEEE, Fellow of IEE and Charted Engineer (CEng).
