Method and device for peer arrangement in single substream upload P2P overlay networks

摘要

The present invention relates to a method of and a device for arranging a P2P overlay network comprising a streaming source and a plurality of peers arranged in distribution layers, the streaming source being arranged to divide data content to be streamed into a plurality of content sub-streams together forming the data content and to distribute the plurality of content sub-streams to the network peers. The method comprises the steps of determining in which one of the distribution layers an individual peer is to be arranged and grouping the peers into a number of peer sets, each peer set being grouped to comprise peers from the same distribution layer and further being arranged to be responsible for distributing a respective content sub-stream. Further, each peer set is assigned a task of distributing said respective content sub-stream to peers of other peer sets arranged in the same distribution layer and to peers arranged in an immediately subsequent layer which further belongs to a peer set being responsible for the distributed respective sub-stream.
