Multimedia applications are emerging in education, information dissemination, entertainment, as well as many other applications. The stringent requirements of such applications make design of cost-e ective and scalable systems di cult, and therefore e cient adaptive and dynamic resource management techniques can be of great help in improving resource utilization and consequently improving performance and scalability of such systems. In this paper, we focus on threshold-based policies, for dynamic resource management, and speci cally, in the context of continuous media (CM) servers. Furthermore, we propose a mathematical model of user behavior and show, through a performance study, that not only does the use of this model in conjunction with dynamic resource management policies improves the system's performance but that it also facilitates signi cantly reduced sensitivity to changes in: (a) system architecture, (b) workload characteristics, (c) skewness of data access patterns, (d...
