The Application Research Of Resources Catalog In The Network Technology Information Organizations

The resources catalog is a path to organize the network technology resources, it performs efficiently in network resources'cataloging, searching, and showing. This paper takes the network technology resources as the research object, and study the resource catalog, and make it come to true. The definition and characteristic of resource catalog and catalog services are introduced, their application and development are descript. Then, three organization ways of the network technology resources are discussed in detail. Combined with the advantages of catalog services, the catalog services application in network technology resources is put forward.(1)Propose the design to the catalog services in network technology and its architecture. Based on that, four model are built including information storeing model, naming model, function model, security model. And then establish the unified metadata store format, confirm the metadata criteria. Also, design the content of the metadata and storing form in detai, propose metadata blue print, catalog information tree and the data storing mapping.(2)Discuss the resource catalog distributed managem, research the DHT algorithm in order to promote it by using of Chord. And there are three promotions, domain partitions and function nodes, improvement of Finger table and set cache in center node. It proves effective after simulation by PeerSim.(3)Build network technology resources catalog service system.The catalog service system in this paper achieves the basic function of the catalog access control, and improves the efficiency of searching. Finally, this system would make efficiently sharing of the resources.
