Impact of Core and Access Network Impairments on IPTV SLAs
by Dr. Ali Begen
Abstract: 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).
Ali C. Begen is a Software Engineer in Video and Content Networking
Research and Advanced Development Group at Cisco in San Jose, CA, where
he participates in the video transport and distribution projects. He
received his Ph.D. degree in Electrical and Computer Engineering from
Georgia Tech in 2006. His dissertation focused on networked
entertainment, multimedia transport protocols and content distribution.
Dr. Begen received the Best Student-paper Award at IEEE ICIP 2003 for
his paper "Rate-distortion optimized on-demand media streaming with
server diversity." In 2008, he received the Most-cited Paper Award with
his paper "Multi-path selection for multiple description video streaming
over overlay networks," from Elsevier Signal Processing: Image
Communication. Dr. Begen is a member of the IEEE and ACM, and currently
