The Research And Application Of Distribution Storage System Deared To Experimental Teaching Of Computer

In recent years, with the development and popularization of the Internet. P2P applications become a research hot spot of network technology again, and the distribution storage system based on P2P technology is the most import areas of research. Talking into account the defect in current storage system based on P2P technology, a JXTA-based distribution storage system is designed.First of all, this thesis has analyzed the P2P technology characteristics, summarized the three kind of P2P models and each kind of domain applications and has analyzed the existing P2P application flaw and insufficiency, extend a P2P application based on JXTA, and then design the distribution storage system, describe the system’s functions; Finally give a detailed explanation to the implement of the models of the functions. The main functions include group management, file search, file sharing, access to shared content, and monitor the peers and some functions additional.According to research, this thesis extends a P2P application frame model, and with the model, successfully develop a distribution storage system, the model extends the scope of application of P2P, the P2P application used in the open P2P networks. This system attempts to apply in local network system. This system uses the pure P2P model, so it eliminate the dependence of the center server, it will not be crashed because of the server is offline or crashed. It has also made full use of the existing network resources and cost savings; Moreover uses this system has lots of incomparable superiorities, such as: non-centralization, expansibility, robustness, high cost performance and high security. This thesis propose a new solution including the control of data-transmission, the structure of search request to avoid the infinity-loop, content manage and peer monitor. The system achieved satisfactory results in practical applications.
