Stochastic TCP
Friendliness: Exploring the Design Space of
TCP-Friendly Traffic Control in the Best-Effort Internet
TCP friendliness has been proposed and
used as a fundamental design principle for traffic control in the best-effort
Internet in the last few years. The current notion of TCP friendliness is well
suitable for applications that can quickly adapt their rates to network
congestion. However, a significant fraction of Internet traffic is multimedia
streaming traffic, which inherently has limited rate adaptability. As a result,
the current notion of TCP friendliness considerably restricts the design space
of traffic control protocols for multimedia streaming.
The goal of this project is to develop stochastic TCP-friendliness as a new
fundamental design principle for traffic control in the best-effort Internet
with the following two major components. First, developing a stochastic
TCP-friendliness framework to qualitatively measure the statistical impact of a
traffic control protocol on TCP performance, and to relatively compare the
statistical impacts of two different protocols. Second, designing and
evaluating a new class of stochastically TCP-friendly traffic control protocols
for multimedia streaming, with the aim to considerably improve both TCP and UDP
performance when compared with existing TCP-friendly protocols.
