An embodiment of the present invention provides a method and device for geographically locating network equipment. The method includes: determining the shortest route length between each landmark and the network equipment IP, and the similarity of the delay vector between each landmark and the network equipment IP. degree; based on the shortest route length between each landmark and the network device IP, and the similarity of the delay vector between each landmark and the network device IP, estimate the route distance between each landmark and the network device IP; according to each The routing distance between a landmark and the network device IP determines the geographic coordinates of the network device. The geographical positioning method and device for network equipment provided by the embodiments of the present invention determine the shortest route length from the perspective of topology, determine the similarity of delay vectors from the perspective of network delay, and comprehensively determine the network equipment by combining the shortest route length and the similarity of delay vectors The geographic coordinates of the location improve the accuracy of positioning.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for geographically locating network equipment. Background technique [0002] The ability to geolocate network devices is essential to many location-aware applications such as content personalization, crime investigation, and location-based access restrictions, among others. Although existing client-dependent geolocation methods can locate client devices very accurately based on technologies such as GPS, cellular networks, or Wi-Fi, they must rely on client support, which makes them impossible to obtain end-device feedback in many applications. Not applicable in certain scenarios, such as: location-based targeted advertising, location-based access restrictions. [0003] In the prior art, in the absence of support from the client, the network device is usually located by means of IP geolocation. Client-independent IP geolocation is a critical issue in the...
