WWW client/server traffic characterization: a proxy server point of view

When performance studies about proxy cache server systems are made, one of the most common difficulties is to identify and to obtain representative workloads. Traces have been used as traditional workload. Gathering traces imply a large amount of time. If a self-similar traffic generator could be used, this problem would be solved, therefore evaluation studies become faster and more flexible. This work contains two parts; first, we perform a study of the self-similar property of several characteristics of the arrival collected traces, such as response size pattern, elapsed request time pattern and so on. Secondly, we model a source and develop a self-similar traffic arrival pattern generator.
