Research Of Information Portal Base On Peer-to-Peer Technology

At present, Information Portal provide a characteristic solution for the information management that bring the people convenience, the most of the Information Portal adopt the mode of Browser/Server . This kind of way can satisfy the customer need currently, but the simply mode of B/S limited its development. Its development is limited with the yoke of server's calculation ability. And the price of the enlargement is biggest, this kind of application mode wasted the calculation ability of huge customer's machine.In this articles, to take the educational realm as an example , the author puts forward the usage to apply the P2P technique to carry on the research project of the reformation to the information portal. According to the detailed system analysis in distance education realm, this article give the stability system design.In this project the author adopt software engineering carries on the system analysis , and built up the function model and the object models of the system. According to the model, that could let us comprehend the system completely. The system adopt the P2P structure model with the center server, and make use of international general exchange language of XML to carry on the, information commutation. This kind of design could make use of the customer's calculation resources sufficiently, and make the transmission and shares of the resource more conveniently and directly . It can make of the whole distance education more close and reliable with keeping the each module independence.The main contribution of this thesis lies in give a new model of Information portal. The system of P2P could support the large of the customer to cooperative, showing its technique advantage of the realm in network :It can deploy quickly with the lower cost strongly and large-scaled distributed application. The current P2P technique application develops a kind of applied mode in the internet, It could make transmission of information more convenient and quick, and raise the function of the information portal to an all new height. So I could believe that it could brought the tremendous convenience for us.
