A SNMP-based algorithm for remote network topology discovery
基于SNMP的远程网络拓扑发现方法

A kind of SNMP-based method was proposed to discovery large-scale heterogeneous IP network topology, which includes Agent discovery, toplogieal data collection and analysis. The main idea in the process of Agent discovery such as construction of packet, elimate redundant data, analyse algorthim and using not-forwarding device-based data was discussed. A solution was given to the intermittent router non-responsiveness, prolonged router non-responsiveness and net number-based target address. The result of the experiment illustrates that the method can capture amount of topology information efficiently. Unit SNMP with traeeroute can improve the integrity of topology discovery obviously.
