| 摘 要： | 针对P2P网络中出现的free-rider现象，提出一种控制点位于服务提供节点上的平衡机制。该机制充分考虑P2P网络拓扑结构不一致的问题，并允许一定数量的free-rider节点存在。实验证明，该机制既能有效利用网络资源，提高交易的成功率，又能对严重的free-rider行为进行抑制。

| Abstract: | Aiming at “free-rider” phenomenon in P2P network, a new balance mechanism in which the control point is on the service providers nodes is proposed. This mechanism promises the existence of free-riders in certain degree and the inconsistency of topology is considered fully. Experimental results prove that this balance mechanism is able to use network resources effectively, and also can restraint the serious free-rider behavior. |
