摘　　要：随着计算机硬件和计算机网络迅速发展,P2P网络模型的优势日渐被人们所重视。基于P2P网络模型的应用也层出不穷,在P2P网络中如何高效地定位节点资源是衡量P2P应用软件价值的重要参考点,也是目前研究的热点。在现有超节点机制和DHT网络的基础上,采用主动网络技术和分层DHT模型,在原理分析和模型设计的前提下,提出了一种主动超节点的DHT分层机制的P2P模型,并通过试验此模型对该机制进行了分析。With the rapid development of computer hardware update and network application,the advantage of P2P network model is approved to be more and more attractive to users.The application of different P2P network model varied a lot and emerged in endlessly.In P2P network,how to locate the node resource fast and effectively is a key point to evaluate the value of P2P application software,which is also hotly researched at present.Base on the present super-node framework and layered DHT model,adopting active network technology and layered DHT framework,and under the precondition of theory analysis and model design,this article claims a new P2P model with active super-node and layered DHT framework and analyzes the performance of this model which via simulate experiments.
