Recent years have seen the growing popularity of video streaming in best effort IP networks. In 2011, Internet video traffic accounted for 51% of all consumer Internet traffic, and High Definition content became the de facto quality level consumed by users. This talk will discuss an SDN -based solution that addresses the high strain the resource intensive video traffic is placing on the underlying network. We will present an OpenFlow-based intelligent in-network caching service that removes the need for transmitting the same Video-on-Demand content end-to-end, multiple times, over the network. Our solution aims not only to improve network utilisation, but also to provide a higher Quality of Experience for the video streaming users of a network.

Bio : Dr. Panagiotis Georgopoulos is a Research Associate (Post Doc) at the School of Computing and Communications at Lancaster University. His work in the Ofelia FP7 EU project is focused on developing an OpenFlow-based in-network caching service for Video-on-Demand traffic. He is also part of the Security Lancaster initiative, for which the University has been awarded the “Academic Centre of Excellence in Cyber Security Research” title. He holds a PhD in Networking and an MSc in Critical Software Engineering from Lancaster University.
