Method and device for arranging peers in a live streaming P2P network

A device for arranging a peer in a P2P network comprising a streaming source and a plurality of peers, the device comprising:

• a processing unit;
• and
• a communication interface, wherein
• said communication interface being arranged to receive a request from a peer entering the network to receive data content;
• said processing unit being arranged to determine, with respect to a real-time playback point of the data content distributed by the streaming source, a latency with which the entering peer is to receive the data content;
• said latency being derived from a determined probability distribution for the latencies with which the network peers receive data content distributed by the streaming source;
• arranging the entering peer in the P2P network according to the determined latency;
• and
• said communication interface being arranged to provide the entering peer with a plurality of randomly selected peers from which the requested data content can be downloaded with an expected probability depending on the determined latency,
• wherein the entering peer is enabled to download, with the expected probability, the requested data content from a selected one of said plurality of randomly selected peers having a lower latency than that determined for the entering peer, and
• wherein the determined probability distribution for the latencies with which the network peers receive data content distributed by the streaming source is based on a distribution level of the network peers in the P2P network.
