The Research And Implementation Of Network Resources Management System Based In WebGIS

The existing problems of campus network resources management is that, the managed resources are not full and the management function is single. It makes the administrators work very tedious. The dissertation's research goal is to create a campus network resources management system based on WebGIS. The management system manages network resources as comprehensive as possible, and it unified management of network resources includes spatial information, static information and operational information.First, the dissertation makes a systematic analysis about the business need of network resources management. It proposes the location, the design objectives and principles, and the functions of system.Secondly, the dissertation comprehensively analyses the realization technology and the deficiencies of WebGIS. It compares the advantages and disadvantages of the WebGIS realization technology based on the plug-ins Plug-in, ActiveX controls or Java Applet process. Then it determines that the WebGIS solution is based on the Java Applet fat client. It researches the realization mechanism of WebGIS based on the Java Applet, using the advantages of the MVC pattern, and applies Struts which achieves the MVC model.Third, the dissertation solves the storage and management of spatial geographical data. It researches the WebGIS application in SVG (scalable vector graphics) to determine that, it applies GML (Geographic Markup Language) for spatial geographic data exchange, uses SVG to describe geographic data, and gives the concrete realization of GML to SVG conversion.Finally, the dissertation detailed analyses the network environment of campus network, proposes an actual methods of the SNMP-based topology discovery, and gives the way of network topology displayed on the geographical campus map.The successful application of WebGIS-based network resources management system has a reference for the network resources management of domestic campus.
