ICMP-based method for logical network topology discovery and analysis
一种基于ICMP的逻辑层网络拓扑发现与分析方法

The faults of SNMP-based method for network topology discovery were analyzed. Then an ICMP-based method for logical network discovery and analysis was presented, which included the discovery and analysis of router topology and the analysis of subnet topology. Path probing and alias probing technologies were used in router topology discovery. The IP addresses of router aliases and the relationship of aliases not in identical subnet were used as basis in subnet topology analysis, and a solution was given to the problem of subnet overlapping.
