Methods, devices and computer program products for facilitating the selection of a sourcing peer in peer-to-peer (P2P) streaming environment are disclosed. These methods allow peers to select candidate source peers in an informed manner with low overhead and minimized complexity. These and other features are accomplished by signalling detailed information regarding the buffer contents to one or more requesting peers. This information includes the presence or absence of requested content segments and a listing of gaps in the requested content segments, which allow the requesting peers to select an appropriate sourcing peer. The selection of a sourcing peer is also effected by considering network connectivity and/or network congestion status between the sourcing and the requesting peers.

Method and apparatus for signaling of buffer content in a peer-to-peer streaming network

A method comprises (a) detecting a packet loss in a partial data packet stream in a peer-to-peer network; (b) signaling an indication of lost packets to one or more sending peers serving the partial data packet stream corresponding to the packet loss; (c) after expiration of a threshold period of time without receiving lost packets, signaling one or more candidate peers a request for retransmission of the lost packets, the candidate peers being peers not serving the partial data packet stream; and (d) receiving the lost packets through one of the candidate peers.
