specific Embodiment approach 1

[0041] Specific implementation mode one: as figure 1 As shown, the geolocation method of a multi-interface router described in the present invention described in this embodiment is described as follows:

[0042] 1. The multi-interface router geolocation method (RLoc) is based on two facts: 1) IP addresses of different interfaces of the same router are at the same location; 2) geographical locations between connected routers are similar. Three heuristics are proposed, such as Figures 3 to 5 As shown, interface election (Interface Election, IE), neighbor election (Neighbor Election, NE) and comprehensive method (IE+NE).

[0043] 2. The implementation process of the multi-interface router geolocation method is as follows:

[0044] 2.1, IE method

[0045] RLoc makes full use of the fact that the IP addresses of different interfaces on the same router are at the same location, and proposes the IE method.

Abstract

A multi-interface router geolocation method relates to the technical field of geolocation. The present invention solves the problem that the existing router-based geographic positioning method needs additional measurement work or requires manual assisted analysis, and the positioning process is difficult to update continuously. The interface IP addresses of multi-interface routers are geographically positioned differently due to router exchange address space. Interface election is used to locate the IP addresses of different interfaces of the same multi-interface router at the same location; Positioning, using neighbor election to make the geographical location of the connected routers similar; combining the above two steps to complete the geographical location positioning of the multi-interface router. The experimental results of the proposed method show that, compared with the relevant data sets, the present invention has significantly improved the coverage and positioning accuracy of the locatable router.

Description

technical field [0001] The invention relates to the technical field of geographic location. Background technique [0002] One of the research contents of cyberspace surveying and mapping is physical resource location, that is, to determine the location of network equipment entities in geographic space. As the cornerstone of building the Internet, the router's geolocation technology is the key to accurately mapping the network space. However, entities in cyberspace are mostly identified by IP addresses, and IP addresses themselves are irrelevant to geographical location. At the same time, a router with multiple IP addresses also increases the uncertainty of positioning. Therefore, how to locate routers is not only one of the core problems of cyberspace surveying and mapping, but also a difficult problem. In recent years, the large-scale router-level topology technology of network topology discovery has been continuously developed, and the detection time, scale, and coverage...
