在網(wǎng)絡管理中引入WebGIS 可以實現(xiàn)在地理信息圖上顯示網(wǎng)絡拓撲。該文介紹拓撲發(fā)現(xiàn)方法、空間數(shù)據(jù)處理模型和拓撲數(shù)據(jù)處理
模型，實現(xiàn)基于地理信息圖的網(wǎng)絡拓撲顯示系統(tǒng)。該系統(tǒng)使用SVG 文檔顯示空間數(shù)據(jù)，描述網(wǎng)絡中各種資源的真實地理位置，為網(wǎng)絡管
理提供了一種新工具。

【Abstract】Network topology can be displayed on geography information map by introducing WebGIS to network management. This paper
describes topology discovery methods, designs spatial data processing model and topology data model, and realizes network topology displaying
system based on geography information map. This system uses Scalable Vector Graphics(SVG) documents to show the spatial data, and describes the
true 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)
