Talk Title: RD Network Services: Differentiation through Performance In


Talk Abstract:
With the Internet offering a single best-

effort service
there have been numerous proposals of diversified

etwork services that align better with the divergent
needs of different
distributed applications. The failure
of these innovative architecture

s to gain wide
deployment is primarily due to economic and legacy

ssues rather than technical shortcomings. We propose
a new paradigm fo

r network service differentiation where
design principles account expli

citly for the multiplicity of
Internet service providers and users as w

ell 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) ser

vices enable a user to
choose between a higher transmission rate or low
delay at a congested network link. An RD router supports

he two services by maintaining two queues per output link
and achieves

the intended rate-delay differentiation through
simple link scheduling

and dynamic buffer sizing. After
analytically deriving specific rules f

or RD router operation
we conduct extensive simulations that confirm e

of the RD services geared for incremental deployment in th
