The design of P2P-based VoD system with VCR functionality

Peer-to-Peer (P2P) network structure is widely employed for video streaming applications due to its high stability, flexible extensibility and ability to share data stream loading among different peer nodes. This paper proposes an interleaved video frame distribution (IVFD) scheme to resourcefully support full VCR functionalities in P2P environment without searching new source. Instead of acquiring video stream data from a single parent peer, each client peer in the IVFD scheme can simultaneously acquire interleaved video data from multiple parent peers. When a client peer carries out arbitrary VCR operations, such as jumps, fast forward/rewind, those parent peers will be able to provide un-continued video stream data for the client peer. As a result, no video source searching is necessary. Simulation results reveal an excellent load distribution performance and a closed to zero response latency for VCR operations.
