随着现代网络规模不断扩大和结构日趋复杂,网络管理成为网络系统正常运行的关键,网管系统的基本功能是以图形方式直观地将被管理对象显示出来,因而拓扑发现是不可缺少的一部分。拓扑发现确定网络元素之间的互连关系,是配置管理的中心,故障管理的基础。 With the continuous expansion of modern networks and their increasingly complicated structures, network management has become the key to the normal operation of network systems. The basic function of network management systems is to graphically and intuitively display managed objects. Topology discovery is therefore an indispensable part. Topology discovery Determining the interconnection between network elements is the foundation of configuration management and fault management.
