摘要： A method performed by a new joining peer device in a peer-to-peer (P2P) network comprises receiving a plurality of buffer maps, each of the received buffer maps associated with a respective other peer device in the P2P network. The method also includes discerning playback positions associated with the received buffer maps, generating a starting offset for the new joining peer using one or more of the discerned playback positions. Requests for portions of a media stream are scheduled in accordance with the starting offset, and the scheduler will build a buffer map from this offset and begin to request the media buffer.

摘要： Systems and methods are provided for scheduling data requests for streaming media data in a Peer-to-Peer (P2P) network. A method is provided to increase a peer's contribution to the whole P2P network by partitioning the data chunks to request into several regions according to their relative time urgency, and data requests are scheduled in an effort to maintain availability of data in each region to a corresponding predefined target amount.
