Research For A Kind Of Distance Learning System Model Based On P2P

Along with information technology fast development, people's existing education content and the education method are receiving the enormous challenge. But computer multimedia technologies and networking day by day mature, caused people's information resource to realize shared highly, fundamentally changed the former people to carry on the communication the pattern, also has provided the very advantageous condition for traditional education's reform and the development. The network by its characteristics and so on strong message resources, friendly interactive performance as well as fine openness receives people's favor more and more, becomes the education on-line development long-distance teaching oneself one kind of trend of development.In recent years, the people increased unceasingly to many kinds of media information's demand, more urgent needed to have can the load bearing real-time interactive video frequency audio frequency information resource. Therefore, "downloads while broadcasts" the class Media Streaming to arise at the historic moment, and obtained the fast development. Media Streaming to solve take the video frequency, the audio frequency information as representative's multimedia information resource in the low band width on-line transmission question, therefore had a better application in the network educational system, caused the teacher and the student has realized the true real-time online cooperation and alternately, caused to regard the audio frequency resources to realize the true digitized management, strengthened learner's initiative and the video frequency, the audio frequency resources controllability, has met learner's study need well.This topic's main purpose is the research designs one based on the P2P technology network teaching interaction system, through the P2P technology can on the direct exchange sharing computer's resources and the service, realizes the highly effective use existing limited resources, solves the C/S pattern system bottleneck problem, simultaneously in the network applies the class media technology in P2P, realizes the network courseware direct seeding, enables the student the synchronization to attend a lecture through the network, in breakthrough distance learning synchronized study efficiency low question.
