An Adapted Multi-way Tree with Holder-chain for Large Scale P2P VoD System
Peer-to-Peer Video-on-demand (P2P VoD) systems have been attracted great interest in research community. Many hybrid methods have been proposed to provide high-quality video-on-demand services to support VCRlike operations, which can also scale to large population of users. In this paper, we propose a hybrid overlay DONet-AMT, which combines DONet and an adapted multi-way tree. DONet is applied to distribute the video segments efficiently. The adapted multi-way tree consists of two layers: a complete multi-way tree and holder-chain, which can support efficient VCR-like operations. Our scheme can ensure that every video segment has k(k>l, typically k>4) replicas at least when the number of peers is large enough, and thus guarantees high data availability. Finally, the performance analysis shows that DONet-AMT can provide better VoD services than DONet-VoD, and DONet-AMT has good scalability.
