摘　　要：分析了已有的拓扑推断理论和算法,针对其不足,提出了一种新的物理层拓扑发现算法.对子网内拓扑发现中的哑设备以及VLAN环境中设备发现的问题进行了研究,使新算法在实际应用中更具通用性,能快速、准确、完整地发现局域网内设备间的连接关系.Network topology auto-discovery plays a very important role in network management. In view of the shortcomings of topology theory and algorithms, a novel algorithm for discovering physical topology is introduced in this paper. The issues of sub-network topology discovery such as dummy equipment and devices found in VLAN environment are deeply researched in this algorithm. In practical applications, this algorithm is more versatile and efficient, and capable of finding the LAN connections between devices more accurately and completely.
