摘要
对非结构化p2p系统,泛洪一直是搜索的理论和实践基石;对于结构化p2p的系统,分布式哈希表(DHT)是其理论基础。由于各自的一些方面的优点,结合两种方法的混合p2p搜索模式近年被提出来。但资源声望值的计算是混合算法的关键,现有的混合搜索方法仍然面临着效率和质量有待于提高的问题,本文在此基础上提出了一种新的方法。
Flooding is the foundation of the theory and practice for finding contents to unstructured p2p system; and to structured p2p system, Distributed hash table （DHT） is the base. The hybrid search model combines the two techniques was proposed recent years because of the advantages of the two techniques. But calculate content popularity is the key of the hybrid search, and current hybrid algorithms are still suffered from the problem either the efficiency decrease or quality decay. And a new solution to the problem is proposed based on these.
