  Abstract

In a Video-on-Demand system, admission control that is used to serve multimedia data efficiently has to be performed by an accurate grasp of the condition of surplus resources. Most of all, we need to adaptable admission control mechanism because the disk has irregular response time caused by external elements of disk, and also has high deviation of amount demanded. In previous admission control schemes, they determined whether a new user is granted or not through a theoretical value. Although they based on the measurement, they left much to be desired in dealing with the service state. Measurement -based statistical admission control scheme, as we suggested in this research, performs 2 processes of off-line process and on-line process in real service environment. Through this processes, we can grasp the accurate resource state of system and adaptively determine the admission according to circumstances. Therefore, it can guarantee both maximum resource utilization and QoS(Quality of Service). On performance evaluations, we show that the video server can utilize maximum resource utilization with QoS guarantee through precision of performance by measurement and adaptable admission control according to the requested bandwidth.
