A Practical Approach to Resource Allocation in Video-on-Demand Servers

Multicast Video-on-Demand services

“…CS organizations ensure a very low latency and high storage utilization, but reconfigurations risk the availability of the entire VoD server. Studies in [3,18,33,64] have shown that video striping improves disk utilization and load-balancing, and hence incieases the number of concurrent streams. [3,64] considered both CGS and FGS, and concluded that the former can support more concurrent video streams than the latter.…”

“…Studies in [3,18,33,64] have shown that video striping improves disk utilization and load-balancing, and hence incieases the number of concurrent streams. [3,64] considered both CGS and FGS, and concluded that the former can support more concurrent video streams than the latter. This is because a disk has a relatively high latency for data access (10--20 ms), and a sufficient amount of video data must be transferred in each disk access in order to improve the utilization of the effective disk lransfer bandwidth.…”

“…Moreover, the replacement operation for one video shouldn't affect the service of other videos residing in the same server. This problem is related to storage organization, and [3] discussed the effect of video partitioning stramgies.…”
