Research And Realization Of Network Topology Management System Based On GIS

GIS(Geographic Information System) is a computer system that can collect, manage, query, analyze, operate and present the geography related information. It can provide very important support platform to give an analysis and decision-making. And GIS is used widely in Geography, resources administration, land layout, environment supervision, electric power industry, traffic administration, city plan, research, education, national defense and so on.As computer and information technology make a very quick progress, the GIS technology grows very quickly in recent years. It strides forward to the specialty, large-scale and sociality. The GIS SW grows rapidly in China and widely used in various industry because of its more high quality-price ratio. But in the combination of geography information and network topology field, problems still exist in China to some extent.The development of Key Network-constructing Technique and Correlative Implementing Project supported by Research on CNGI QoS Mechanism give a very good solution for this. This system integrates the geography information and QoS management of telecommunication network. It fulfills the strict service quality requirement of telecommunication service...
