Application Of The P2P Technology In The Video Conferencing System

With the development of multi-media and network technology, video conferencingsystems has came into being, which is the communication system can make the informationof sound、image and text transport from one area to many others. As the video processing andnetwork technology limitations, the video conferencing systems there are many inadequate,such as network bandwidth limited resources, when a large number of users increased, theamount of data increases, the quality of audio and video will appear was experiencing adownward trend. Then with the rapid development of P2P technology, and relatedtechnologies mature, to the video conferencing system has brought about good opportunitiesfor development. After a detailed analysis of P2P after it with the existing video conferencingtechnology used bonding, presents a P2P-based video conferencing systems andcommunication technologies.In this paper, which of making the project of video conferencing system in Theprocuratorate of Baiyun zone to the background explore the scheme of video conferencingsystem that base of the P2P technology. At first, through the investigation of each relevantpart of the procuratorate, I draw a full understanding of requirement in the fact of videoconferencing system, to analyze that the QOS of network not be matched video conferencingsystem and the server "bottleneck".Secondly, I give a project of design, which consist of themode of P2P by server and the structure of video conferencing system. Thirdly, base of theseproblem, I deal with the algorithm of pieces choice of BT and a set of optimized bandwidthprograms, which make a improvement. Fourthly, I make a detailed describe of how to put intoeffect with the video conferencing system, especially the VOD, which system server、WEBserver、database server and the client. Fifthly, I make the test consist of the point to point andVOD.Finally,I make a expectation of the future in this research area.
