New Scheduling Policy for Peer-to-peer Based Video-on-demand Storage
Recently,Peer-to-Peer based Video-on-Demand systems(VoD/P2P) have received a lot of research focus.Due to the high storage requirements in VoD and the limited storage resources in P2P networks,the storage design for these systems is challenging.In this paper,we propose a new storage strategy,Equivalent Data Random Access(EDRA),with the objective of system resource minimization,or system capacity maximization.Our experiments reveal that EDRA is effective for VoD/P2P storage.Compared with traditional strategies,EDRA can improve the system capacity by 58-73 percent in terms of the number of concurrent users.
