ABSTRACT
We propose a peer-to-peer (P2P) streaming system that multicasts live video as well as provides the live video as Video-on-Demand (VoD) during the live session. The proposed system allows users to individually pause and resume a live video stream, and to view video that was streamed before the particular user joined the session. Since live video content naturally results in many users watching it online at the same time, the P2P concept is leveraged to reduce server load. We extend our Stanford Peer-to-Peer Multicast (SPPM) protocol, originally designed for live video multicast, to support playback control. To achieve this in a P2P fashion, peers store received video packets in their local buffer and forward them at a later time when requested by other peers, which is called time-shifted streaming. To understand interaction between live and time-shifted traffic, we analyze video availability of the proposed system, which refers to how many peers possess video contents of a particular position. Motivated by the analysis, we propose fast prefetching and a parent selection scheme suitable for fast prefetching in order to further reduce server load by disseminating video quickly. Fast prefetching is possible because the relaxed transfer deadline of time-shifted streams and peers' extra uplink bandwidths are exploited. With simulations and mathematical analysis, it is shown that fast prefetching not only alleviates the requirement of server bandwidth by expediting video dissemination, but also mitigates video disruption due to peer churn.

    In a peer-to-peer (P2P) video-on-demand (VoD) system, each peer contributes a limited disc storage and stores some watched movies to offload the servers when these movies are requested. When the contributed disc storage of a peer is full, to minimize the server load, which movie should be...

    Video-on-Demand (VoD) services are effectively provided to the users when implemented using Peer-to-Peer (P2P) networks. As each peer node shares its resources, such as bandwidth, storage space, and computing power to their neighbors which is not prevalent in normal networks, the requests from...

    Building a scalable video on demand (VOD) architecture is essential for the optimization of the VOD service cost and to support a very large VOD content library. The peer-to-peer (P2P) VOD architecture works towards achieving this goal, by distributing the video files to the user's set-top boxes...

    The peer churn rate in the peer-to-peer (P2P) video-on-demand streaming service is much higher than in the P2P live streaming service, which makes the data scheduling problem more challenging. First, the available upload bandwidth information used in the data scheduling scheme is often...
