obtaining requests Management Method for peer identifiers in order to enter in P2P mode of content they store, and management apparatus and equipment associated network.

A management device (D) that is part of a communication network (R1) to which can be connected items of communication equipment (T1-T4) constituting peers storing content data and operating in P2P mode. This device (D) comprises analysing means (MA) adapted to, in the case of reception of a request for obtaining peer identifiers, said request designating content, from a peer (T1), i) to access a tree structure comprising leaves (associated with peer identifiers storing content associated with content identifiers) and location nodes (associated with location information, representative of location of peers associated with leaves that are attached to them, and with content information, representative at least of content identifiers that store these peers), in order to determine the location of the leaf associated with the content identifier designated in the received request, then the peer identifiers associated with leaves that are attached to this determined location node and said content identifier, and ii) order the transmission to the requesting peer (T1) of the determined peer identifiers.
