摘　　要：网络拓扑发现是网络管理的基础。目前网络组建普遍采用包括核心层、汇聚层、接入层的三层交换网络模型,其中“三层交换”和VLAN技术被广泛应用于不同厂商设备组建的网络中。该文提出了符合现代流行网络模型的、含VLAN异构IP网物理拓扑发现算法。使用该算法可以准确地发现含VLAN异构IP网物理拓扑结构。The network topology discovery is the basis of network management. A hierarchical design model which includes access layer, distribution layer and core layer is widely used in a construction of a switched LAN. ＂Layer 3 switching＂ and VLAN is used in equipments from different vendors. This paper proposes an algorithm which accords to and includes the physical topology discovery of heterogeneous IP networks with VLAN which is designed and implemented according to hierarchical design model.Using this algorithm can find the accurate physical topology of heterogeneous IP networks with VLAN.
