Innovating the Multi-Provider Internet

Withthe Internet offering a single best-effort service, there have beennumerous proposals of diversified network services that align betterwith the divergent needs of different distributed applications. Thefailure of these innovative architectures to gain wide deployment isprimarily due to economic and legacy issues, rather than technicalshortcomings. We propose a new paradigm for network servicedifferentiation where design principles account explicitly for themultiplicity of Internet service providers and users as well as theireconomic interests in environments with partly deployed new services.Our key idea is to base the service differentiation on performanceitself, rather than price. The proposed RD (Rate-Delay) services enablea user to choose between a higher transmission rate or low queuingdelay at a congested network link. An RD router supports the twoservices by maintaining two queues per output link and achieves theintended rate-delay differentiation th
 rough simple link schedulingand dynamic buffer sizing. After analytically deriving specific rulesfor RD router operation, we conduct extensive simulations that confirmeffectiveness of the RD services geared for incremental deployment inthe Internet.

Who is Sergey Gorinsky?

SergeyGorinsky is a native of Skhodnya, USSR and currently works as anAssistant Professor at the Applied Research Laboratory in theDepartment of Computer Science and Engineering at Washington Universityin St. Louis, USA. He received the Ph.D. and M.S. degrees from theUniversity of Texas at Austin, USA and Engineer degree from MoscowInstitute of Electronic Technology, Zelenograd, Russia. Prof.Gorinsky’s primary research interests are in computer networking anddistributed systems. His research contributions include multicastcongestion control resilient to receiver misbehavior, analysis ofbinary adjustment algorithms, and network service differentiation basedon performance incentives.
