They replicate movie segments cooperatively under the constraint of their storages. In order to achieve scalability in user capacity overcoming the limitation in core network bandwidth, servers are deployed close to user pools. We study the provisioning of large-scale video-on-demand (VoD) services to distributed users. Achieving this goal requires: (1) a piece selection strategy that effectively mediates the conflict between the goals of high piece diversity, and the in order requirements of media file playback, and (2) a new incentive mechanism, which supports media streaming.

This is in contrast with the Bittorrent protocol which uses rarest block download first. Our approach gives higher priority to the blocks that are at the earlier point playback point. Bittorrent uses rarest block download first policy which is not favorable for media streaming. We propose peer to peer multimedia streaming solution based on the Bittorrent content distribution protocol. The importance of this capability is that peer will now have ability to start enjoying video before the complete download of the file.
Although BT was created for the distribution of time insensitive content, in this paper we try to find out what are the changes that are required in-order to incorporate streaming in it. Simulation results show that our replication strategy can substantially reduce access costs compared to a commonly used replication scheme and a state-of-the-art replication scheme.īitTorrent in the recent years has been one of the most effective mechanisms for the P2P content distribution. In this algorithm, we first solve the ILP problem as a relaxed LP problem, and then heuristically round the resulting fractional LP solution to integer towards ILP feasibility. We then propose a fast algorithm to solve it with bounded approximation error. In this paper, we first formulate the content replication problem as an integer linear programming (ILP) problem, which is proven to be NP-hard. IMVS presents a new challenge in content replication: which video segments to replicate to support interactive view-switching during an IMVS session. To provide scalable IMVS services, a content provider often deploys distributed content servers with heterogeneous storage capacities in order to collaboratively replicate video segments for their clients. In interactive multiview video streaming (IMVS), a client can watch the multiview video and interact with it by switching to different viewing angles at frozen moments.
