Abstract
The accuracy of self-similar processes that are
widely used to model Web server systems is eval-
uated using simulation. Specifically, we consider
two processes with self-similarity from a single
origin: either with a realistic self-similar arrival
process or with a realistic service-time distribu-
tion, but not both. A detailed examination and
