Digital Organisms Station Copy Of The Design And Implementation Of The Management,

With the development of Internet, people pay more attention to the network service quality. The applications of the traditional client / server architecture model are very difficult to support a huge number of users. These years, the popularity of P2P technology extremely large the extension of service, let a customer play the role of a server, make up for the traditional client / server model. But all these P2P tools focus on a particular application, lacking a systematic way for managing resources, so the utility of resources was at a low level. Hence, a new generation of distributed system—DOS (Digital Organism System) has been designed to arrange the resources and storage spaces of computers in a wide area network in the 8010 research office. DOS which combines with distributed character of P2P focuses on resource management to meet the need of various network applications.The primary task of DOS is resource management and task dispatch. For the resource management, the most important part is resource accessing, furthermore, the efficiency of resource accessing must be taken into consideration all the time.The document designs and realizes duplicate management module in station of DOS on the analyzing of P2P system and traditional distributing system. The duplicate management in station of DOS has managed each node's export disk space; maintain the relationship of each node's disk space mapping; as well as operating multi duplicates in the station and maintain these duplicates information. We make use of the modularization and layering design to make each node could reasonable organized, come into being an organic system; and effectually used each node's disk space, improved performance of system access and guarantee the data's security.Tests show that duplicate management in station of DOS achieve the design of the functional requirements, the reading and writing performance of DOS can be good to satisfy the needs of users.
