Based On The Research And Application Of The Pnrp Protocol Peerchannel Shared Storage Model,

Resource Sharing business is an extremely important function of distributed application systems,providing resources sharing business logic in distributed application,it can widely and effectively integrate network resources, promote the friendly information flowing fast, reduce repetition of the existing resources, greatly improve the storage efficiency of network application. With the development of the network communication technology, the demand of communication efficiency is increasingly high. Effectively improving the efficiency of network connections, improving the utilization of the network resources is the key to modern network communication technology. Meanwhile, application program is becoming more and more important to the user's experience, users can use network resources as local resources. Providing a virtual platform of local resources, to achieve a "immersion" experiencing effects is an urgent task for distributed application at present.Paper aims to improve the distributed sharing of document resources, Microsoft WCF(Windows Communication Foundation) as a platform, extensively discusses the insufficient and potential demand of the existing P2P applications, deeply analyzes the related technologies of which PeerChannel documents shared storage model depends on, based on PNRP agreement, it includes the basic concept, process and characteristics of PNRP Resolution Protocol, PNRP cloud technology concept, IPv6 technical advantages, Teredo address translation technology, PeerChannel peer network technology, WCF communication model, access control security model, WPF(Windows Presentation Foundation) interface drawing technology and so on. Paper based on the current demand for P2P application system, comes up with a solution based on the communications infrastructure of PNRP agreement and custom address resolution service, PeerChannel peer grid application as the platform, combineing WCF communication framework, WPF interface mapping framework, configure security model shared storage. On this basis, via the deployment of a center mode server mode to improve the fitting efficiency of Distributed Network Communication resource, it makes the perfect solution for the whole sharing storage system.Thesis implements a PeerChannel documents shared storage systems,using PNRP accord as communications basis, the current popular elements in the system, such as smooth and transparent interface from WPF,with the function of" as dragging as using",, PeerChannel's custom analysis services, a layered application design, build a "immersion" experience distributed sharing storage system and the system realizes the retrieval, publishing, browse, security features of sharing resources, use WCF design framework to build the entire network communication module, employ separate information storage scheme, they have improved system efficiency, reduced user's store costs. The paper finally tests the actual operation of the system, tracks the efficiency of address resolution and status fitting.
