Abstract
In the presence of multiple mirror servers that can serve
the same information, clients can improve their perfor­
mance when downloading large files by conncurrently re­
trieving different parts of the file from different servers. In
previous work, experiments with a single client have shown
the potential for parallel downloading schemes to improve
the performance perceived by this single client. In this pa­
per we consider the question of what happens when par­
allel downloading is widely adopted within the Internet. To
that end we start with an experimental evaluation of various
parallel downloading schemes and their performance from
the perspective of a single client. We use these results as a
benchmark for a set of simulations in which we investigate
