On Improving the Accuracy of Internet Infrastructure Mapping

This study identifies a method to create fine-grained multilayer maps of the Internet’s structure, which are currently lacking. We begin with an investigation current techniques for geolocating hosts using passive, active, and hybrid methods. is followed by survey fundamental problems that IP geolocation must address. The points obvious difficulties in Delay-Distance models suggests use Return Trip Times can lead highly misleading results. therefore develop new procedure combines state-of-the-art methods avoid many Internet topology mapping, whilst creating finer-grained internet than those available. tested on UK infrastructure conducting series tests distributed measurement provided RIPE Atlas platform. Our results show we accurately geolocate routers between two endpoints map involved our measurements. Researchers have long recognized scarcity ground truth datasets where concern. As byproduct reported this paper, validation dataset hundreds addresses geo-coordinate landmarks or vantage points, desirable research. Finally, discuss some limitations method, summarise next steps toward accurate complete maps.
