摘要: 为克服通用多子网交换域拓扑发现算法复杂、适用性差的缺点,提出一种基于三层交换与VLAN的拓扑发现算法。对虚拟局域网进行抽象后实现VLAN分组,并对每个VLAN组进行拓扑发现。分析结果表明,将VLAN信息融合到拓扑发现过程中,能准确发现VLAN网络的拓扑结构。

Abstract: To overcome the defect of complex and low applicability belong to a common multi-domain network topology discovery algorithm, this paper proposes a topology discovery algorithm based on three layer switching and VLAN. The algorithm abstracts the VLAN network, groups all the VLANs, and does the process of topology discovery in each VLAN group. Analysis results show that it makes the best use of VLAN information during the process of topology discovery, and can accurately discover the topology of a VLAN network.

Key words: three layer switching, VLAN, topology discovery
