Welcome to TULIP

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. TULIP's purpose is to geolocate a specified target host (identified by IP name or address) using ping RTT delay measurements to the target from reference landmark hosts whose positions are well known (see map or table). Knowing the speed of light in fibre or copper (roughly 0.6*c, we use 1ms. 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. Lateration is applied on these distance estimates to estimate the position of the specified host on the globe. We are focusing on a platform agnostic, open non-proprietary tool (c.f. 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. and Europe specifically in less well developed countries.
