一种城域网物理拓扑快速自动发现实现方法

摘要

According to the experience of metropolitan area network(MAN) management software design and development, this paper proposes for quick discovery of metropolitan area network physical topology based on SNMP asynchronous scan. The method has been applied to project and solved problems on the integrity of the device search, the topology discovery speed, the accuracy of topology identification during topology discovery, which has got good effection in project application.%根据城域网网管软件开发过程中的设计经验，本文阐述了一种基于路由接口地址空间和SNMP异步扫描的网络物理拓扑快速发现的方法，并在具体项目中予以实现和应用，解决了拓扑发现过程中面临的设备搜索的完整性、拓扑发现的速度和拓扑判定的准确性三个主要问题，并取得了良好的效果。
