Abstract

This paper demonstrates the existence of considerable dependencies between Web server arrival and service times, as well as strong dependencies within the arrival process. We derive a heavy-traffic stochastic-process limit for Web server performance, under various control policies, that captures these forms of correlations. This includes an analysis of control policies that provide near-optimal expected response times while also maintaining good response time variance properties.
