ADMISSION CONTROL ALGORITHM FOR MULTIMEDIA SERVER: A HYBRID APPROACH

A multimedia server employs admission control algorithm (ACA) to control client traffic in order to increase utilization of server resources. The admission process accepts new clients as long as it does not violate service requirements of pre-existing clients. In this paper, we are proposing a hybrid admission control algorithm (HACA) that can handle a considerably large number of clients simultaneously by engaging different admission policies for different clients based on their service requirements. The performance of an ACA is dependent on the disk-scheduling algorithm it uses. In this paper we consider various disk-scheduling algorithms to measure the performance of our proposed algorithm. We also introduce some techniques for minimizing overflow of rounds that significantly improve the performance and demonstrate the effectiveness of HACA.
