摘要
对现有使用ICMP协议、FDB地址转发表进行网络拓扑发现的算法进行分析,提出了一种基于SNMP协议并适合校园网环境的网络层拓扑发现和链路层拓扑发现算法.该算法能够快速准确地计算出整个被管网络的二层和三层拓扑结构.
Based on the analysis of currently used network topology discovery methods using ICMP protocol and FDB,which stands for Forwarding Database,a SNMP-based topology discovery algorithm is brought up in this paper.It is suitable for the topology calculations of both network level and data-link level in a single administrative domain just as campus network environment.Using it,an accurate topology graph of both layer-3 and layer-2 can be constructed rapidly.
