A P2P overlay network, which comprises a streaming source and a plurality of peers arranged in distribution layers, is arranged such that the total number of distribution layers of the overlay network is reduced. First, the upload capacity of each individual 5 peer is determined and a maximum number of overlay peers to which said each individual peer can upload is calculated. Then, the peers are arranged in hierarchical order in relation to the streaming source on the basis of the maximum number of peers to which each individual peer can upload data. A higher number results in the individual peer being arranged in a distribution layer closer to the streaming source 10 while a lower number results in the individual peer being arranged in a distribution layer further from the streaming source. Thus, the total number of distribution layers of the overlay network is reduced. Figure of publication: Fig. 1 -- ----------- 0----- 0----- 0- o 0) ww w- w---- Figure. 1 |
