The Study Of P2P Resource Sharing Technology And Appling It On Education Platform

The technology of P2P resource sharing is different with the traditional pattern of storaging resource on Server, it allows resources and services loosely distributed in each node on the network side, the point of user can shared resources and services from the other nodes directly, don't from the Server, it implements the distributing of resources sharing. And the technology of P2P resource sharing allows the storage space of sharing resources can be extended infinitely,, much beneficial to alleviate the pressure of storage resources and the consumption of network bandwidth on the server side.The education platform of "Fonda" is a education platform of immediate correspondence based on P2P technology, this platform has achieved the management of mark, immediate correspondence, tutorials online, broadcast of video, operating Assess, notification, P2P resource sharing and other functions, but the foundation of sharing resources System is not imperfect enough, only if nodes build the relation of classmate or the relation of "teacher and student" can down resource from others, didn't build the centralized management of resource, it results the problem of hard to share resource,the speed is slow and the rate of the use of resource.Study the technology of P2P resource sharing in this paper, I put forward a type formula of P2P resource sharing with the own characteristics of the existing distance education platform, the formula use centralized P2P network model. The list of resource saved on the index-Server and the real resource saved on each user-point, user-point can depart from the index-Server to down resources from other user-points when it obtain the information of real resources, this solve the problem of hard to share resource,the speed is slow and the rate of the use of resource, then achieve a prototype base on the formula, it implements look over resource by classification,"folder sharing","download-to-many","down continue of P2P" and other functions. And verify the feasibility of the formula by the test of system.
