DEVICE AND METHOD FOR CONTROLLING DISSEMINATION OF CONTENT DATA BETWEEN PEERS IN A P2P MODE, BY USING A TWO-LEVEL RANDOMIZED PEER OVERLAY AND A DYNAMIC UNCHOKE MECHANISM

摘要

A method is intended for controlling dissemination of content data in a peer-to-peer mode between peers (P1-P16) connected to different communication networks (N1-N3). This method comprises the steps of: i) building, for each peer, a first peer set comprising active peers that are primary connected neighbours close to this peer in terms of network cost and a second peer set comprising active peers that are secondary connected neighbours of this peer, chosen at random irrespectively of network cost, and ii) dynamically determining into each peer a capacity of content data it is ready to receive from peers of the second peer set, taking into account its current capacity to receive content data from peers of the first peer set, in order to optimize the peer-to-peer dissemination of the content data.
