Techniques for Content Delivery at Scale in Current and Future Network Architectures

Talk Title: Techniques for Content Delivery at Scale in Current and Future Network Architectures

Abstract: On-demand video streaming dominates today's Internet traffic mix. For instance, Netflix constitutes a third of the peak time traffic in the USA. Nearly half of UK online households have accessed BBC's shows through its on-demand streaming interface, BBC iPlayer. Using UK-wide traces from BBC iPlayer as a case study, this talk will characterise users' content consumption at scale and discuss techniques that can be deployed at the edge by users to substantially decrease the load in the Internet. We will survey both well-known techniques such as peer-assisted video-on-demand, studying whether it works at scale, as well as new edge-caching mechanisms that can potentially be deployed today. We will conclude by exploring new directions for future network architectures, to address the roots of the pain points observed in our user workload, in a "clean" fashion.
