拓扑服务中融合GIS与拓扑发现技术的研究

Research on Topology Service Developed by Merging GIS and Topology Discovery Technology

传统的网络拓扑服务通过拓扑发现技术,描述了网络节点间的逻辑连接关系,基于GIS技术的网络拓扑服务,则体现了网络传输线路、网络节点间的空间连接关系。对这二种网络拓扑服务的实现展开研究,提出一种将两者相融合的方法,将网络资源及其拓扑关系视图化,以便于网络资源的保存、查询、管理,在计算机上实现准确真实的空间分析和可视化表达,实现了两者的优势互补,为网络资源利用,故障检测、定位、修复提供一种全新、强大的辅助工具。

Traditional network topology service describes logic connection between through topology discovery technology. And network topology service based on GIS shows network nodes spatial connection between network transport lines and between network nodes. This paper investigates the realization of the two network topology services, and then brings forward a new method of combining the two, which visualizes network resources and their topology structure in order to provide conservation, query and management to network resources. It also realize exact and real spatial analysis and expression visually on computer by making full use of the superiority of the two methods. This method provides a novel and mighty assistant instrument for the utilization of network resources and fault detection, orientation, renovate.
