The invention relates to a network supervising device (20) and a method at a network supervising device of managing distribution of data content streams in a segment of a peer-to-peer (P2P) network. The invention further relates to a peer device (t3, t4, t5) and a method of uploading data content streams at a peer being constrained from uploading the data content streams to further peers in a segment of a P2P network. The network supervising (20) device for managing distribution of data content streams in a segment (11) of a P2P network (10), which network segment comprises one or more peers (t1-t5) being constrained from uploading the data content streams to further peers. The network supervising device comprises a processing unit (21) being arranged to receive a request for a data content stream (c3) from at least one of the peers (t3, t4, t5) being constrained from uploading the data content streams to further peers, and to identify whether at least one peer exists within the network segment being capable of uploading the requested data content stream, which peer is downloading the requested data content stream. If no peer within the segment is currently rendering the requested data content stream, the processing unit identifies whether at least one currently idle peer (p9) exists within the network segment, which currently idle peer is capable of uploading the requested data content stream. Further, the processing unit is arranged to assign to the at least one peer downloading the requested data content stream, or if no such peer is available, to assign to the at least one currently idle peer, to upload the requested data content stream to the peer being restrained from uploading the data content streams to further peers. |
