基于IPv6的三层混合P2P覆盖网络模型

研究现有的非结构化对等(P2P)网络，结合IPv6以及人类社会资源查找方法，提出一种三层混合P2P覆盖网络模型。在该模型中，具有相同IPv6网络前缀的节点组成一个域，域内节点根据属性相似性划分为若干个兴趣组，组内节点管理功能由智能节点完成，域内路由节点负责跨域路由消息。仿真结果表明，该模型能提高资源查找效率，缩短查找时延，减少消息路由跳数。

Three-tier Mixed P2P Overlay Network Model Based on IPv6

Based on the study of the existed unstructured Peer-to-Peer（P2P） network,this paper structures a three-tier mixed P2P model which combine P2P with the method of humans searching resource.In the model,peers with the same IPv6 network prefix compose a domain,peers with the same property compose groups in every domain,Intelligence Peer（IP） manages terminal peers in every group,routing peer is responsible for query routing between domains.Simulation result shows the model can enhance resource search efficiency,shorten search delay and reduce routing hops.
