| Abstract: | In this paper, an efficient admission control algorithm is proposed to provide different levels of services based on the server workload characteristics. Service quality is ensured by periodical allocation of system resources based on the estimation of request rate and service requirements of prioritized tasks. Admission of lower priority tasks is restricted during high load periods to prevent denial-of-services to high priority tasks. Response delays of the high priority tasks are bounded by the length of the prediction period. |
