The present invention provides a network topology display method and device. The method comprises the steps of: determining a sub network capable of abstraction processing from original network topology, wherein the sub network comprises at least two network devices, and a network link and a network interface between the at least two network devices; performing abstraction processing of the at least two network devices included by the sub network and the network link and the network interface between the at least two network devices to obtain a virtual network device; displaying current network topology, wherein the current network topology comprises the virtual network device formed after the sub network is subjected to abstraction processing. The current network topology can completely display the effective information in the original network topology and can convert the original network topology to the current network topology on the basis without reduction of information display soas to meet the large-scale network topology management and display demands, improve the user usage feeling and improve the value of the network topology.
