一种新型远程网络拓扑发现及分析算法

分析了利用SNMP协议、ICMP协议进行网络拓扑发现的原理和子网掩码分析的方法,并针对现有方法的不足提出参考建议。提出一种基于多种网络探测技术的RT远程网络拓扑发现分析算法,该算法不仅注重网络实体信息的收集,更突出了对获得实体信息的分析。最后,通过比较不同方法对仿真网络环境拓扑发现的结果,证实了RT算法得到网络拓扑结果的完整性和准确性。

New remote network topology discovery and analysis algorithm

This paper analyzed the principle of collecting information of network topology with SNMP and ICMP, the faults of these means and some advice were discussed. Then, a new RT algorithm of remote network topology by synthetizing many probing techniques was presented. The algorithm not only put emphasis on the collection of network devices infomation,but also gave prominence to the analysis of these infomation. Finaly, the integrality and veracity of the result of this new network topology discovery algorithm were proved by compared the results of different way,all based on an emulating network environment.
