Video Transport, Distribution and Quality of Experience

Tuesday, 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).

NOTE: This talk is accessible to both undergraduate and graduate students. Dr. Begen will answer questions about opportunities at Cisco at the end of the talk.
