A method for operating a node of a communication network including a plurality of peer-to-peer nodes, the node being linked with predetermined neighbour nodes among the plurality of peer-to-peer nodes, includes: a) storing, on a first storage area, node information indicative of predetermined data required by the node to become an information provider node; b) waiting to receive from at least one information provider node of the neighbour nodes describing information of data that can be provided by the information provider node; c) at the receipt of the describing information from the at least one information provider node, checking in the first storage area if the data that can be provided by the at least one information provider node match at least in part the predetermined data required by the node; d) in the affirmative, deleting in the first storage area the node information indicative of the matching data; and e) in the negative, forwarding the describing information received in c) to at least one of the plurality of peer-to-peer nodes.
