| 摘 要： | P2P系统的一个核心问题是如何高效定位所需资源。该文提出了一种基于DHT(distributedhashtable)的层次式资源定位模型,将层次式引入结构化P2P系统。模型将节点组织成一个多层网络,每层可以包含多个DHT子网。该模型有助于解决P2P网络的可扩展性和可管理性问题。模拟测试表明,模型在路径长度和访问延迟方面的性能优于原DHT。

| Abstract: | A core problem in peer-to-peer systems is the efficient location of the node that stores desired resource.This paper presents a DHT-based hierarchical resource locating model and introduces hierarchy into structured P2P system.The model organizes nodes into a multi-layer network and every layer may consist of many DHT sunbets.The model can help to solve the problems of scalability and manageability of P2P network.Simulation tests show that the model is superior to original DHT at path length and access latency. |
