Our department tea on October 27 will feature a guest speaker, Marwan Fayed, from the University of Stirling in the UK. Marwan will talk about his work in adaptive video streaming. As usual, lunch will be available, too.
Speaker: Marwan Fayed, University of Stirling, Scotland, UK
Title: Network-layer Fairness for Adaptive Video Streaming
Abstract: Netflix, iPlayer, YouTube, and the like, are now the dominant sources of traffic on the Internet. Recent studies observe that competing adaptive video streams generate flows that lead to instability, under-utilization, and unfairness behind bottleneck links. Additional measurements suggest there may also be a negative impact on users' perceived quality of experience as a consequence. While it may be intuitive to resolve application-generated issues at the application layer, in this presentation I shall demonstrate the merits of a network layer solution. I will present a new network-layer metric that reflects user experience. Experiments using our open-source implementation in the home environment reveals that the network-layer may just be the right place to attack the general problem.
Marwan Fayed received his MA from Boston University and his PhD from the University of Ottawa, in 2003 and 2009 respectively, and in between worked at Microsoft as a member of the Core Reliability Group. He joined the faculty at the University of Stirling, UK in 2009 as under the Scottish Informatics and Computer Science Alliance (SICSA) scheme. He has since been appointed 'Theme Leader' for networking research in Scotland. His current research interests lie in wireless algorithms, as well as general network, transport, and measurement in next generation edge networks. He is a co-founder of HUBS C.I.C., an ISP focussed on rural communities, and serves on committees of IEEE and ACM conferences.
