Abstract :
We address two issues in this work: on one hand, we consider and compare five throughput predictors to be used in a Web system in order to estimate its future performance and, on the other hand, we propose an adaptive QoS-aware admission control algorithm that is based on a resource allocation scheme that includes a throughput predictor. In order to obtain a low overhead, the monitoring of the arrival traffic to the Web system is done following an adaptive time slot scheduling based on the burstiness factor that we defined in a previous work. Simulation results of the behaviour of the five throughput predictors and the admission control algorithm are presented and discussed.
