Abstract
We focus on service differentiation policies for Web servers where clients have different QoS requirements and the environment has large fluctuations in the client arrival and service patterns and in the QoS class mix. We propose an adaptive admission control mechanism that offers ser- vice differentiation among client classes and maximizes the effectiveness of the server's operation. Using actual traces from the 1998 World Cup web site, we conduct a detailed analysis of the proposed policy and show that it meets the performance challenges of a robust QoS policy.Keywords
