摘要： 在混合P2P系统中，散播自适应算法提高了资源搜索的效率。该文针对随机散播算法在资源知名度传播方法上存在的冗余信息和资源知名度一致性之间的矛盾，提出一种基于节点地址的资源知名度传输方法，采用资源知名度根据节点地址不进行重复发送的方法，结果证明该方法比随机散播算法具有更少的传输时间及更低的传输开销。

Abstract: In a hybrid P2P system, gossip adaptive algorithm promotes the efficiency of resource search. Against the contradiction in the randomized gossip algorithm between the redundant information in the transmission method and consistency of the resource popularity, this paper introduces a new transmission method based on the node address. The method avoids the duplicate sending upon the node address, which results in less transmission time and cost than randomized gossip algorithm in the experiment.

Key words: hybrid P2P search, randomized gossip algorithm, resource popularity
