George Kesidis received his BASc in EE from the University of Waterloo, Canada, in 1988 and his MS and PhD in EECS from U.C. Berkeley in 1990 and 1992 respectively. He was a professor in the ECE dept at the University of Waterloo from 1992 to 2000. He joined Penn State in 2000 and is now a professor in the CSE and EE depts there. His research has spanned different topics in communication/computer networking including traffic engineering, security, incentives engineering, and machine learning. He has published two books on networking, has been an associate editor of three networking journals, and has served on many NSF cyber trust and networking panels and conference technical program committees, including as TPC co-chair of 2007 IEEE INFOCOM. Prof. Kesidis is a senior member of the IEEE.
Περίληψη Ομιλίας
We first give a brief overview of the current network neutrality debate and discuss related issues of usage-priced Internet access. Neutrality and migration of “managed” services to commodity Internet applications motivate service differentiation, which will be describe using a simple two-class model including delay and throughput-sensitive traffic. How service differentiation can make more efficient use of network resources will be demonstrated, particularly for lower capacity access networks. We then focus on delay-sensitive traffic and study flat-rate versus usage-based pricing under overload conditions. Our results suggest that in overload scenarios, usage-based pricing is advantageous in that system congestion is reduced and users’ perceived utilizations are increased. The talk concludes with an overview of related existing technology.
