一种基于ICMP的逻辑层网络拓扑发现与分析方法

ICMP-based method for logical network topology discovery and analysis

分析了基于简单网络管理协议(SNMP)的网络拓扑发现方法存在的不足,提出一种基于因特网控制消息协议(ICMP)的逻辑层网络拓扑发现和分析方法,该方法包括路由器拓扑发现与分析、子网拓扑分析两个步骤。其中路由器拓扑发现采用路径探子和别名探子两种技术;子网拓扑分析依据路由器别名ip地址和别名不在同一个子网的关系,最后对子网重叠问题进行了分析并给出了解决方案。

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.
