In this paper, we develop a unified model of a hierarchical Video-on-Demand(VoD) system by integrating the storage and network subsystems. Rather than restricting the analysis to an isolated subsystem the performance of the VoD system is analyzed as an end-to-end system. On a system-wide basis, request handling and admission control policies are designed to minimize global performance metrics. Through our simulation, we compare different request handling policies and show that a hierarchical VoD architecture with request handling that allows retrials at more than one resource will minimize overall blocking.
