New Algorithm for Topology Discovery on Ethernet-based Industrial Networks
一种新型工业以太网拓扑结构发现方法*

This paper addresses the difference of topology discovery between the network layer and the data link layer.And we present a new algorithm based on the SNMP and STP,working for the topology discovery in large industrial networks.Perfor-(mance) results show that,compared with the traditional discovery algorithm,this algorithm has smaller influence,lower comple-(xity) and better expansibility.
