Title: 25 years of quality of service research - where next? |
Abstract: We present the design of a packet network where paths are dynamically selected based on quality of service (QoS) metrics that can be specified by the users of the network or by the network's access points. The approach uses on-line measurement associated with the traffic itself, and reinforcement learning throughout the nodes of the network, to try to satisfy the users' QoS objectives. The talk will present numerous measurement studies of this approach on a large laboratory test-bed. The presentation is based on our recent paper in the Communications of the ACM (July 2009), which integrates different aspects of our research including network design, performance evaluation models and methods, and probability models of neuronal networks.

Abstract: The beginnings of quality-of-service research and standardization go back at least 25 years and have consumed a significant fraction of our communal resources. In this talk, I will try to summarize my personal take on lessons we have learned along the way in resolving the fundamental tension between sharing and isolation. It is also clear that the network environment of transmission-only routers is starting to change as new applications emerge. I will also argue that QoS is largely about reliability and predictability, and that we should attempt to leverage the availability of unreliable, but cheap, components to improve user-perceived reliability, rather than the traditional telecom approach of engineering highly reliable components.

Bio: Erol Gelenbe is a Professor of Electrical and
Electronic Engineering Department, at Imperial College. His theoretical research develops
probability models in computer science, and
he designs self-aware adaptive network
protocols such as the Cognitive Packet
Network, and tests them via large scale
laboratory experiments. Erol has introduced
G-networks, as well as models of of spiked
neural networks and learning algorithms,
as well as models of gene regulatory networks.
He is active in funded research programmes
in the UK and the EU. A member of the Turkish Academy of Sciences, of Academia Europaea,
and of the French National Academy of Engineering, he is a Fellow of the IEEE,
Fellow of ACM and of IET (London). Erol has received "honoris causa" doctorates from
several universities, and scientific prizes such as the ACM SIGMETRICS Life-Time Achievement
Award and the Prix France Telecom of the
French Academy of Sciences. His
decorations include the Knight Grand Officer
of the Order of the Star of Italy, Commander of Merit of Italy, and Officer of Merit of France. |
Bio: Prof. Henning Schulzrinne, Levi Professor of Computer Science at Columbia University,
received his Ph.D. from the University of
Massachusetts in Amherst, Massachusetts.
He was an MTS at AT&T Bell Laboratories
and an associate department head at
GMD-Fokus (Berlin), before joining the
Computer Science and EE departments
at Columbia University. He served as chair
of Computer Science from 2004 to 2009.
Protocols co-developed by him, such as
RTP, RTSP and SIP, are now Internet
standards, used by almost all Internet
telephony and multimedia applications.
His research interests include Internet
multimedia systems, ubiquitous computing, mobile systems. He is a Fellow of the IEEE.
