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 JA - IEEE International Conference on Multimedia Computing and Systems, 1999 PB - IEEE VL - 1 SN - 0-7695-0253-9 M3 - 10.1109/MMCS.1999.779196 ER -
