Evento: 'Seminário: Prof. Don Towsley (UMass)'

Eventos PESC (Palestras, Seminários, etc.)
Palestras, Seminários, etc. do PESC/COPPE/UFRJ.
Data: Tuesday, August 16, 2011 At 14:00
Duração: 2 Horas

O Prof. Don Towsley, da Universidade de Massachusetts Amherst (UMass), EUA, estará visitando o LAND-PESC/COPPE na próxima semana. Apesar de atuar na área de Redes, seu trabalho de pesquisa é bem abrangente, e ele é um dos autores mais citados da área de Computação (um de seus artigos mais influentes tem mais de duas mil citações), além de ter recebido prêmios renomados da IEEE e ACM por excelência científica. Ele irá proferir uma palestra na próxima terça, dia 16/8, às 14h, na sala H219 (ver detalhes abaixo).

Title:
Swarms: First Class Citizens in the Future Internet

Abstract:
The current Internet consists of tens of thousand different interconnected autonomous networks. It was designed to support large populations of point-to-point content transfers. This introduces considerable headaches due imbalances in traffic flows, which has the effect of complicating network management, reducing the robustness of the Internet, and reducing user performance.

In this talk, I review the sources of traffic in the Internet over the last 20 years. We will observe that this an increasing fraction of traffic was generated by peer-to-peer (P2P) "swarm" technology from 2000 to 2007. I examine how and why P2P swarm technology simplifies network management, and makes the Internet and applications more robust. Unfortunately, the use of this technology has decreased since 2006 and shows every sign of continuing to do so. Thus, the rest of the talk focuses on and characterizes an architecture that encourages and makes swarms full class citizens. I will focus not only on the problem of transfering content but also on the problem of locating content.

Short Bio:
Don Towsley received a B.A. degree in physics and a Ph.D. degree in computer science, both from University of Texas. He is currently a Distinguished University Professor in the Department of Computer Science at the University of Massachusetts - Amherst. Professor Towsley has been a Visiting Scientist at AT&T Labs - Research, IBM Research, INRIA , Microsoft Research Cambridge, and the University of Paris 6. Dr. Towsley's research interests include network measurement, modeling, and analysis. He serves on the editorial boards of Journal of the ACM and IEEE Journalof Selected Areas in Communications, and has served as Editor-in-Chief of the IEEE/ACM Transactions on Networking and on numerous editorial boards including those of IEEE Transactions on Communications and Performance Evaluation. He has been active on the program committees for numerous conferences including IEEE Infocom, ACM SIGCOMM, ACM SIGMETRICS, and IFIP Performance conferences for many years, and has served as Technical Program Co-Chair for ACM SIGMETRICS and IEEE INFOCOM, and IFIP Performance conferences. He has also served as Chair of the IFIP Working Group 7.3 on computer performance measurement, modeling, and analysis, and as an officer or advisor of ACM SIGMETRICS and ACM SIGCOMM. He is one of the founders of the Computer Performance Foundation. Dr. Towsley has received the 2007 IEEE Koji Kobayashi Computer and Communications Award , the 2007 ACM SIGMETRICS Achievement Award, the 2008 ACM SIGCOMM Award, the 1999 IEEE Communications Society William Bennett Award, and several conference and workshop best paper awards. He is also the recipient of the UMass Award for Outstanding Accomplishments in Research and Creative Activity, the University of Massachusetts Chancellor's Medal and an Outstanding Research Award from the College of Natural Science and Mathematics at the University of Massachusetts. He has twice received IBM Faculty Fellowship Awards, and is a Fellow of the IEEE and the ACM.
