Target IP (Internet protocol) geographic position locating method based on nearest common router

Abstract

The invention relates to a target IP (Internet protocol) geographic position locating method based on a nearest common router. The method can effectively solve the problems that the errors are great, the precision is low, and the actual requirements cannot be met. The method comprises the following steps that a time delay detection packet and a path detection packet are used, and the time delay and the path information from a detection source to a target IP and a landmark node are measured; the path information from the detection source to the target landmark node is used for finding a landmark with the nearest common router as the target; the time delay from the detection source to the landmark and the router is used, and the time delay between the landmark and the router is calculated; the time delay and the position information of the landmark are used, and a conversion coefficient of the distance restraint and the time delay between the router and the landmark are calculated on the basis of the cosine law; the time delay and the conversion coefficient are used for calculating the distance between the router and the landmark; the position of the nearest router is calculated on the basis of three-point locating, and is used as the locating value of the located position of the target IP. The method has the advantages that the operation is easy, the use is convenient, the effect is good, and the locating precision on the target IP can be improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a target IP geographic location positioning method based on the nearest common router. Background technique [0002] Geolocation of network entities is an important new technology for network applications, which can give the geographic location of a network node at a certain level of granularity, also known as IP location. As the basis of location-based service (LBS), IP positioning technology has a wide range of applications, such as providing targeted advertisements for people in the area based on the user's geographical location; adaptively adjusting website display based on the visitor's geographical location language, analyze web page access logs to extract market data, formulate network infrastructure deployment strategies and find faulty nodes, etc. Therefore, developing IP positioning technology has important research significance. [0003] There are public...
