Application Of P2P Video Stream In Network Education

Traditional education through internet is based on C/S or B/S mode, with the user of education through internet rapid development, the video server will overload become to the bottleneck of the internet bandwidth and impact the QoS. So there is a badly need to construct an internet education system based on P2P video stream and improve the qualities of education through video stream.The process of video stream translation through P2P networks is researched in treatise. It is proposed a P2P video stream system which solves the problem of generation and reception of the video stream as well as the construction of P2P networks. A topology that based on the network topology in a tree topology and mesh topology of a combination of mixed topology is put forward. The tree topology is adopted in inter-regional communication, and the mesh topology is adopted in the region communication. In order to join the network nodes as soon as possible, the treatise put forward a strategy that the shortest path to the shortest period of time combined with the election node strategy. When nodes are elected in the inter-regional, it is using the shortest path strategy; and when the node is failure, using the strategy of the shortest period of time. This treatise is employed the transmission strategy that it will decide to transfer the amount of data, according to a dynamic network of the actual situation of the transfer, and download the data block at least the owner for the purpose of quickly transfer data.The mutual decision of data quantity strategy is proved that it could distribute data block into net quickly and equably, and this mixture model could proper reduce communication traffic through the simulation experiments. Lastly, we discussed the correlative problems in using P2P video stream model through internet video education and give out system structure of realization.
