    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.

    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： A method of providing data to two client devices on a first network having a shared cache from a server device on a second network. An instance of substantially simultaneous requests for data being made to a server from two client devices on a same network is identified. In response to a first request for the data being received at a first point in time a first one of the two client devices is served with the requested data from the server such that the data is stored in the shared cache. The second one of the two client devices is directed to make a second request for the data at a second point in time, later than the first point in time, so that the requested data is available in the stored cache.
