摘　　要：针对对等联网(P2P)的特点,基于用户对分配的资源的满意度,提出了一种P2P带宽资源分配的方法。首先,描述了P2P网络中现有分配机制的不足之处,然后从竞争资源的节点满意度方面出发,以最大化竞争节点的效益为目标进行共享资源的分配。通过与其他分配机制的比较和分析可知这种机制很适合P2P网络环境的需求,有效地利用了资源且满足了用户的请求。Aiming at the characteristics of Peer to Peer （P2P） network, a Resource Distribution Mechanism Based on Satisfaction Degree called RDM-SD is presented. The RDM-SD is based on the user satisfaction degree. Firstly, this paper describes the disadvantages of resource distribution mechanism. From the perspective of the competing nodes＂ satisfaction, maximizing the competing nodes utility is the main goal to distribute the resource. Finally, the paper compares the RDM-SD with the others. The performance analysis shows that the RDM-SD is adaptive to the P2P network and efficiently utilizes the resource as well as satisfies the users request.
