在网络管理中引入WebGIS 可以实现在地理信息图上显示网络拓扑。该文介绍拓扑发现方法、空间数据处理模型和拓扑数据处理模型，实现基于地理信息图的网络拓扑显示系统。该系统使用SVG 文档显示空间数据，描述网络中各种资源的真实地理位置，为网络管理提供了一种新工具。关键词：拓扑发现；地理信息系统；网络管理；可伸缩矢量图形Network Topology DisplayBased on Geography Information MapXU Bing, XU Xiao-dong(Institute of Computer Science and Communication Engineering, Jiangsu University, Zhenjiang 212013)【Abstract】Network topology can be displayed on geography information map by introducing WebGIS to network management. This paperdescribes topology discovery methods, designs spatial data processing model and topology data model, and realizes network topology displayingsystem based on geography information map. This system uses Scalable Vector Graphics(SVG) documents to show the spatial data, and describes thetrue location of the resources in network. This system is a new tool for network management.【Key words】topology discovery; Geography Information System(GIS); network management; Scalable Vector Graphics(SVG)
