Design And Implementation Of Multimedia Network Taching System Based On P2P Technology

The modern education technology is one kind of new educational technique which produces along with the modern science and technology development, the multimedia network teaching system is the modern education technology important manifestation.In the multimedia network teaching system, the video on demand (Video-on-Demand, was called an important content which VOD) and the document sharing system was we constructs, in which VOD has realized the different long-distance visible teaching form, but document sharing realized the teaching resources differently to use.The video on demand system is based on flows one kind of network multimedia systems which the media technology realizes, generally uses the B/S pattern in the campus intranet.But in the campus net the document sharing system uses also is the B/S pattern.However, the B/S pattern too is big to the server performance dependence, when has excessively many users simultaneously visit the server, the system grade of service receives the very great degree the influence.Therefore, to the existing multimedia network teaching system performance bottleneck question, this article will use mixes P2P the pattern to solve.This article to conducts the research based on the mixed P2P multimedia network teaching system, the design and the realization, does the prime task includes:Domestic and foreign multimedia network teaching present situation research, current multimedia network teaching system characteristic in development technology research.Proposed based on mixes the P2P multimedia network teaching system, and carries on the research analysis to in system design process some new characteristics and the new technology.The encompassment based on the mixed P2P multimedia network teaching system, carries on the analysis to the system, the system system design and the function module design.The system main function includes: Member function, immediate correspondence, P2P resources sharing and video on demand.The system after the development and the test, erected in the correlation school local area network and applies, has solved traditional C/S, in the B/S system the single server own resources limit question, reasonable has used the idle resources, enabled the overall system ability to obtain the enormous enhancement.Simultaneouslycoordinates the immediate correspondence function, enables the learner to be able abetter exchange, also enable the system the teaching effect to have the remarkableenhancement.
