ABSTRACT
We present Topology-based Geolocation (TBG), a novel approach
to estimating the geographic location of arbitrary Internet hosts. We
motivate our work by showing that 1) existing approaches, based
on end-to-end delay measurements from a set of landmarks, fail to
outperform much simpler techniques, and 2) the error of these ap-
proaches is strongly determined by the distance to the nearest land-
mark, even when triangulation is used to combine estimates from
different landmarks. Our approach improves on these earlier tech-
niques by leveraging network topology, along with measurements
of network delay, to constrain host position. We convert topology
and delay data into a set of constraints, then solve for router and
