Distribution and Quality of Experience
Ali C. Begen
October 20, 4pm
Location: BA 1180
In this talk, we present
the video technologies developed at Cisco in the service provider space,
including Content Delivery Systems (CDS), Video-on-Demand (VoD) and IP
Television (IPTV). We illustrate the problems experienced during the video
transport and distribution in core and access networks with examples. We discuss
several techniques for improving network reconvergence times and reducing the
network loss as well as their performance/cost trade-offs and their impact on
IPTV Quality of Experience (QoE).
talk is accessible to both undergraduate and graduate students. Dr. Begen will
answer questions about opportunities at Cisco at the end of the talk.
Begen is with the Video and Content Platforms Research and Advanced Development
Group at Cisco. His interests include networked entertainment, Internet
multimedia, transport protocols and content distribution. Ali is currently
working on architectures for next-generation video transport and distribution
over IP networks, and he is an active contributor in the IETF in these areas.
Ali holds a Ph.D. degree in electrical and computer engineering from Georgia
Tech. He received the Best Student-paper Award at IEEE ICIP 2003, and the
Most-cited Paper Award from Elsevier Signal Processing: Image Communication in
