Abstract:
Innovating the Multi-Provider Internet
With
the Internet offering a single best-effort service, there have been
numerous proposals of diversified network services that align better
with the divergent needs of different distributed applications. The
failure of these innovative architectures to gain wide deployment is
primarily due to economic and legacy issues, rather than technical
shortcomings. We propose a new paradigm for network service
differentiation where design principles account explicitly for the
multiplicity of Internet service providers and users as well as their
economic interests in environments with partly deployed new services.
Our key idea is to base the service differentiation on performance
itself, rather than price. The proposed RD (Rate-Delay) services enable
a user to choose between a higher transmission rate or low queuing
delay at a congested network link. An RD router supports the two
services by maintaining two queues per output link and achieves the
intended rate-delay differentiation th
rough simple link scheduling
and dynamic buffer sizing. After analytically deriving specific rules
for RD router operation, we conduct extensive simulations that confirm
effectiveness of the RD services geared for incremental deployment in
the Internet.
Who is Sergey Gorinsky?
Sergey
Gorinsky is a native of Skhodnya, USSR and currently works as an
Assistant Professor at the Applied Research Laboratory in the
Department of Computer Science and Engineering at Washington University
in St. Louis, USA. He received the Ph.D. and M.S. degrees from the
University of Texas at Austin, USA and Engineer degree from Moscow
Institute of Electronic Technology, Zelenograd, Russia. Prof.
Gorinsky's primary research interests are in computer networking and
distributed systems. His research contributions include multicast
congestion control resilient to receiver misbehavior, analysis of
binary adjustment algorithms, and network service differentiation based
on performance incentives. Prof. Gorinsky's work appeared at top
conferences and journals such as ACM SIGCOMM, IEEE INFOCOM, and
IEEE/ACM Transactions on Networking. He has been serving on the
Technical Program Committees (TPCs) of IEEE INFOCOM 2006, 2007, 2008,
2009, ICNP 2008, and other networking conferences. H
e co-chaired
the TPCs of High-Speed Networks (HSN 2008) at IEEE INFOCOM 2008 and the
Symposium on Future Internet Architectures and Protocols (FIAP 2008) at
ICCCN 2008. He is serving as a TPC Vice-Chair of ICCCN 2009 and as a
Vice-Chair of theIEEE Communications Society (ComSoc) Technical
Committee on High-Speed Networking (TCHSN).
