Research On Management System Of Network Services Resource Based On Jini And GIS

At present, requirement of network services has been increasing and the network services have also been developping massively. How to manage and integrate a large number and ever-changing of these services has become a difficult problem to be must solved. Because the current GIS is difficult to the dynamic changing and manage of network service resources, it is need to build the management system of network services to facilitate the collection, integration, optimize the allocation and publish these services. By this system, the changes based on time or space of network services can be feedback quickly and released to the public in time.To construct the management system of network services, this thesis made an in-depth study covering such theories as Jini and GIS. In the thesis, the services management and optimization of resources allocation were analyzed. Jini technique was introduced from the perspective of service-oriented. The thesis expounded Jini's characteristics such as distributive, heterogeneous, dynamic, open, etc. The advantages and limitations of Jini were also pointed. MAPGIS-IMS7.0 was carried out on a depth study, and there was detail introduction of its architecture, server and client's function warehouse. Subsequently, the research method and construct process of management system of network service resource based on Jini and GIS were introduced. The service model based on Jini was the important component of the management system of network service. The system designed good agency service to resolve the problem of registering the Jini service and managing service information by moblie users. The kind of devices which lack resources could apply Surrogate technique, designed their respective Surrogate, stored in equipment in form of JAR file. When the devices working, they load the JAR file into the Surrogate host which can provide the Jini environment, solved the problem of the resources limited equipments used latest Jini services. At the same time, the system also provided friendly and abundant operation interface for Internet customers, provided services of dynamic registering, monitoring, querying and related function of GIS .So people can enjoy more comprehensive and more convenient service.Research on management system of network services resource based on Jini and GIS gives full play to the advantages of WebGIS and Jini. It is a better solution to the network services'key issues, for example, integration, management and release.A management system of network services based on MapGIS-IMS7.0 and Jini is raised, and its service pattern and functional modules are also designed. Finally, using the service of print application to demonstrate the effectiveness and operate advantages of network services resource management system. The research of Jini and GIS techniques in the thesis and the successful development of the prototype system provide reference and experience for Jini's future applications and the development of GIS new application pattern.
