The Design And Implementation Of Internal File Sharing System Of Enterprise Based On P2P

In recent years, with the enlargement of the enterprises’ scale and the sharpincrease in different resource of documents, it is necessary to establish enterpriseinternal file sharing system. Compared with the traditional C/S mode, P2P technologymakes full use of clients, so the sharing system does not completely depend on theserver that it can effectively avoid the bottleneck which appears with the enlargement ofthe network. P2P technology makes direct communication between users possible,further improves the efficiency of file sharing.This thesis first deeply explores and studies the related theory of P2P technology,system structure, development trend as well as the advantages and disadvantages, thenthe eDonkey protocol and the implementation method is studied. Then this paper studiesthe related theory of Lucene search algorithm, and improves the form of wordsegmentation. Based on this above, the participle way was improved, and a distributingway was raised by adding a Chinese word list, it could match the word throughconstructing a word tree, made it more effective to support local area network filesharing system, improved document and related information search efficiency.Based on the study of the basic theory, basic structure of P2P, using eDonkey2000agreement as the basic protocol that implements the P2P architecture implements thebasic of P2P network, analysis and design sharing system. Finally, this papersummarizes the research contents of this project, and give the outlook for futureresearch.
