Abstract
This paper criticises the notion that long-range dependence
is an important contributor to the queuing behaviour of real
Internet traffic. The idea is questioned in two different ways.
Firstly, a class of models used to simulate Internet traffic
is shown to have important theoretical flaws. It is shown
that this behaviour is inconsistent with the behaviour of real
traffic traces. Secondly, the notion that long-range correlations
significantly affects the queuing performance of traffic
is investigated by destroying those correlations in real traffic
traces (by reordering). It is shown that the longer ranges
of correlations are not important except in one case with an
extremely high load.
Description

This paper looks at the phenomenon of long-range dependence. It shows that certain long-range dependent models give answers which contain infinities and also that this behaviour will not be detected by a naive modelling approach. The work is extended in the JCCS paper
