反馈机制在P2P网络资源搜索中的应用研究

Application Research of Feedback Mechanism on Resource Search in P2P Network

资源搜索是P2P网络的关键问题。目前P2P网络资源搜索中对反馈机制的应用研究较少,这样每次搜索对成功历史没有充分利用,搜索效率较低。该文针对此问题提出了基于改进的Rumormongering协议的资源发布算法BDFB(BidirectionFeedback),并将其应用到P2P网络资源搜索的反馈机制研究中,充分利用成功历史,提高资源在网络中的知名度,从而提高P2P网络中资源搜索效率。

Resource search is the key problem in P2P network.At present,researches of feedback mechanism applications on resource search in P2P network are less,thus the efficiencies on resource search are very low because histories about every successful search are not used enough.Under this situation,this paper introduces an algorithm-BDFB(Bidirectional Feedback)based on improved Rumor mongering protocol,and applies it into the researches of feedback mechanism in P2P network resource search to increase the repute of resources which will improve the efficiencies on resource search.
