A Link Layer Topology Discovery Algorithm Based on STP
Wan Xiao-qiang · Jisuanji gongcheng · 2006
With the development of large scale switching network, the study is transferred from network layer to data link layer. The link layer topology discovery can discover the physical topology internal a LAN, which the network layer topology discovery can not discover. A link layer topology discovery algorithm based on spanning tree algorithm is proposed. The algorithm gets the STP information from the bridge MIBs with the tool of SNMP. It can calculate the link layer topology on the basis of the information. The algorithm is simple and with high performance in application.
