远程网络拓扑发现算法研究

Research of remote network topology discovery algorithm

网络拓扑发现技术是近年来网络安全领域的一个研究热点。指出了网络拓扑发现的意义,讨论并分析了网络拓扑发现的一些常用方法,包括Traceroute、别名、根据多个已知IP地址分析子网掩码以及利用SNMP协议收集网络拓扑信息等相关的技术原理,在此基础上提出了一种基于多种网络探测技术的新的远程网络拓扑发现算法,并以仿真网络环境实例分析及证实了该算法得出网络拓扑结果的完整性和准确性。

Network topology discovering has become a hotspot of network security field. The meaning of the remote network topology discovering was pointed out. The principle of traceroute, alias, subnet guessing from a cluster of addresses and collecting information of network topology with SNMP were analyzed. A new algorithm of remote network topology was proposed by synthesizing many probing technologies above all. The integrality and veracity of the result of this new network topology discovery algorithm were proved based on an emulating network environment.
