Abstract: A control device belongs to a network equipment connected to a communication network to which are coupled communication equipments of users capable of storing contents. This control device comprises i) a first analyzing means arranged for determining respective popularities of contents of a collection from at least user information, and for determining a number of replicas for each content of this collection from at least its determined content popularity, and/or ii) a second analyzing means arranged for determining content preference(s) of users from content ratings, and iii) a computation means arranged for determining location(s) for storing the replica(s) of each content, from the determined content replica numbers and/or the determined user's content preferences, in order to optimize the access to these contents by the users.

Abstract: The invention concerns a method for flow control in a peer-to-peer live streaming communication network comprising a plurality of nodes characterized in that the rate at which a node sends information to another node increases proportionally to the quantity of information present at node which has not yet reached node and decreases proportionally to a value attached to the link connecting node to node.
