Embodiments of the present application provide a network topology discovery method and device, for performing a comprehensive analysis on results obtained after network topology discovery by using multiple types of network characteristic data, improve accuracy of network topology discovery. A specific solution comprises: collecting network characteristic data of a network element in a network; obtaining at least two corresponding link subsets respectively by using at least two types of topology discovery algorithms and according to the network characteristic data, gathering all links in the link subsets into one set to obtain a first link set, combining same links in the first link set, and for multiple links having only one same port, retaining only a link having a largest confidence value in the multiple links and deleting a remaining link, to obtain a second link set; obtaining a network topology of the network according to the second link set.
