Research And Design Of Interactive Teaching System Based On P2P Network

With the popularity of the Internet and broadband technologies, education has entered the digital network, intelligent, personalized stage of development, and new communications technologies for the transmission of information and knowledge to provide the latest teaching more channels building a network of educational resources for a breakthrough. However, the majority of network resource sharing are still teaching methods and the lack of interaction and lack of the two-line problem put P2P technology for network learning system can be a good solution to share network resources and user interaction. P2P make it free access to the knowledge, the dynamics of learning possible.The main purpose of this project is to design a interactive network teaching systems based on P2P technology, P2P technology to directly exchange through the sharing of computer resources and services, achieve efficient utilization of the limited resources available to address bottlenecks in the system C/S model; P2P network applications in streaming media technology, the network courseware broadcast network to keep pace saw students, Synchronous distance education breakthrough study, the problem of low efficiency.This thesis first researches the principle of the P2P network technology, and detailed analysis of the strengths and weaknesses of P2P technology, also explained the three types of P2P network structure and the application of P2P technology; Secondly, this thesis designs a interactive network teaching systems platform based on P2P network, including live classroom. courseware download and demand , on-line exercise, on-line examinations, exercises management, online exchanges functional modules; Finally, by researching DONet model based on Gossip agreement, including adding nodes and management description cache mapping and data exchange, data scheduling, the failure to restore and partner, this thesis realizes construction P2P network system platform and implements streaming media data transmission modules.
