A system for establishing a client/server type relationship in a hybrid peer to peer network connects a first peer () to a second peer () implementing a predetermined function (F) in that peer to peer network. To this end, the first peer () has a superpeer () capable of establishing a list (LF) of the active peers () implementing the function (F) in the service of the peers of the network and of sending that list (LF) to its peer (). The first peer () can then establish a client/server type relationship with a second peer () selected in that list (LF).

This messaging system is for use in a peer to peer network including at least one depositary peer (PX, PR) adapted to store a message in one or more portions and to send a message notifying the completion of the storage of that portion to at least one superpeer (SPX) of the peer (PX) of the depositor (X) of the message (M). This superpeer (SPX) is adapted to send a notice of reception of the message to a peer (PY) of the addressee (Y) of that message, that notice including a list of the depositary peers (PX, PR) and an identifier of each of the portions of said message stored by each of the depositaries (PX, PR).

Messaging service in a peer to peer type telecommunications network

A method for determining the dynamics of a logical network, said network comprising a plurality of communication nodes (, i, k). The method comprises obtaining (), in a node () of the network, of at least one item of information (Li, Jk) relating to a modification of the neighborhood of said node, in the course of a predetermined period. The method also comprises determining (), in said node of the network, of a local dynamics corresponding to at least one sum of at least part of the information obtained.
