基于DHT的跨协议P2P资源共享模型

互联互通是现有P2P系统面临的一个核心问题。本文提出了一种基于分布式哈希表DHT结构的跨协议P2P资源共享模型,将多种P2P系统的资源共享信息分布式存储于系统的底层DHT网络中。模型中的每个节点都具有多种P2P客户端的实现,并能够参与到多P2P系统中,智能发现相异P2P系统中的相同共享资源。通过从多P2P系统中并行下载数据,系统极大地减少了用户响应时间和文件下载完成时间,并提供了内容完整性QoS保障。仿真结果表明,该模型在系统鲁棒性、可扩展性及用户体验等方面优于现有的P2P系统。

A DHT-Based Cross-Protocol Peer-to-Peer Resource Sharing Model

In this paper,a DHT-based cross-protocol P2P resource sharing model is proposed to address the interconnection and intercommunication problem in the existing P2P systems,where the DHT network stores the resource information for each P2P system. The peer in the model implements each P2P protocol and can participate in multi P2P systems and intelligently find out the same resources among them. Through downloading the resources in parallel from multi P2P systems,the model can provide essential functions to the...
