Multilateration computes the position of an object by measuring its distance from multiple reference positions. Calculating an object's position in two dimensions requires distance measurements from 3 non-collinear points (hence Trilateration). Lateration is the calculation of position information based on distance measurements.

and Europe specifically in less well developed countries. Traceware from Digital island or Edgescape from Akamai) that can be used to evaluate the effectiveness of this technique for hosts outside the U.S. We are focusing on a platform agnostic, open non-proprietary tool (c.f. Lateration is applied on these distance estimates to estimate the position of the specified host on the globe. is equivalent to 100km), the minimum ping RTT measurement of 5 pings from each landmark site gives a rough estimate of the fibre + copper cable distance of the landmark from the target host. Knowing the speed of light in fibre or copper (roughly 0.6*c, we use 1ms. Using ping RTT delay measurements to the target from reference landmark hosts whose positions are well known (see map or table).

TULIP's purpose is to geolocate a specified target host (identified by IP name or address) TULIP is a geolocation utility developed by National University of Sciences and Technology (NUST) School of Electrical Engineering and Computer Sciences (SEECS) and the Stanford Linear Accelerator Center (SLAC) Internet End-to-end Performance Monitoring (IEPM) project.
