Resource reservation and dynamic admission control for distributed multimedia systems
In the literature, different approaches have been proposed to achieve an admission control which can highly guarantee a Quality of Service (QoS) in distributed multimedia systems. Through this paper, we propose a new method for admission control in distributed multimedia systems namely a feedback control architecture for distributed multimedia systems (FCA-DMS). This method is based on (i) continued knowledge of the network and of the video servers workload, and (ii) the supervision and auto-adaptation of system load. The network and the video servers workload are computed by a QoS controller integrated in the master server of the FCA-DMS architecture. Our proposed solution consists of maintaining an up-to-date broad view of the systems behaviour from the collected measurements to databases of available video servers and to databases of available videos and their locations. We run extensive simulations to test the validity of our solution. The simulation results show that our solution leads to a good QoS with all workload conditions. This performance results from the continuous supervision of admission of client queries according to the real workload variations.
