The main purpose of many current peer-to-peer (P2P) networks is off-line file sharing. However, a potentially very promising use of such networks is to share video streams (e.g., TV programs) in real time. In order to do so, the peers in a P2P network who are interested in the same video stream may employ application level multicasting (ALM). In existing P2P networks, peers may exhibit behaviour which is problematic for ALM: peers tend not to donate any resources (free-riding), and they arrive… CONTINUE READING
