ABSTRACT:
The invention concerns a computer software product comprising a plurality of peers (2′, 4, 5) adapted to participate in a peer-to-peer network where the computer software product comprises detection means for detecting actual presence information of a peer and where the computer software product comprises retrieval means for retrieving actual information about the peer, where the detection means is located on neighbor partner peer (4) of the peer (5) for detecting continuously whether the peer provides still actual information and the computer software product comprises propagation means for outdating the information about this peer in case of detecting that the peer is not alive.The invention further concerns a network device and a method therefore.
