Stochastic models of bandwidth
estimation
Abstract
Estimation of available and bottleneck bandwidth is an important task in many
end-user applications and network monitoring tools. The goal of bandwidth
estimation is to infer the residual rate available in the path and the speed of
the slowest link using end-to-end measurements. This is usually accomplished by
injecting a sequence of probe packets into the path in question and monitoring
their output dispersion at the end of the path. Under certain mild assumptions
on cross-traffic, available bandwidth and capacity of the slowest link can be
extracted from the inter-packet spacing of probe traffic at the receiver. Unlike
prior work that relies on fluid models of cross-traffic, this project studies
bandwidth estimation using stochastic (i.e., packet-level) cross-traffic arrival
and explains why existing fluid-based tools often do not perform well in
practice.
