摘要：We study about homogeneous and heterogeneous systems, where all peers have to share available resource between their own and other peer’s needs. A system of peers who use their capacity-limited access links both for their upstream and downstream connections. In the selfish approach, each peer would like to exploit use his full capacity only for his downloads. However, if all peers acted selfishly, so the entire system would be collapse. In order to motivate peers to cooperate, we propose a heterogeneous along with bittorrent used to exploit his full capacity for his both upstream and downstream. Since the differentiation is based on nodes prior contributions, the nodes are encouraged to share large information/services with each other. So all peers act as rationally, trying to achieve their maximum tradeoff capacity.
