摘要
由于对等网络上的资源不是在一个单一的服务器上,而是分散在各个对等体上,理想状态下各个对等体是平等的,但它们在提供资源能力上又是各不相同的,因此,在进行查询搜索时,需要对这些对等体给予不同的优先级和处理方法。本文在分析对等网络中现有的搜索机制的基础上,提出了一种利用节点的分组和层次化来提高搜索的效率,增强系统的扩展性的搜索模型。
The resources of the P2P network are distributed with many different peers,Every peer is equal to any other one in the ideal situation.But the abilities that they provided with the resources are different,so it needs different priorities and solution methods while delivering searches.This paper introduces a group-based layer searching model according to the observed searching methods in the P2P network,which improves the efficiency of searching and adapts to the dynamic in P2P system.
