摘　　要：如何在对等系统中快速准确地搜索到目标资源已经成为当前研究的热点。现在的许多DHT算法基本上没有考虑实际网络层的拓扑，导致形成的对等系统结构混乱。本文针对这个问题提出了基于分层网络的单跳DHT算法，该算法将网络层距离较近的节点组成小网络，搜索发起节点只需要在小网络内部的一步查询就可以找到目标节点。How to locate the target resources quickly and accurately in peer-to-peer system has become a hotspot of current research. Now lots of DHT algorithms are basically not consider the actual topology of the network layer, so the structure of the formed peer-to-peer system is disordered. In this paper, one-hop DHT algorithm based on layered network is put forward for this issue. In this algorithm, nodes with small distance on network layer make up Small-network, and searching node can find target node by one step inside the Small-network.
