Query: traIXroute: Detecting IXPs in traceroute paths   Internet eXchange Points (IXP) are critical components of the Internet
infrastructure that affect its performance, evolution, security and economics.
In this work, we introduce techniques to augment the well-known traceroute tool
with the capability of identifying if and where exactly IXPs are crossed in
endto- end paths. Knowing this information can help end-users have more
transparency over how their traffic flows in the Internet. Our tool, called
traIXroute, exploits data from the PeeringDB (PDB) and the Packet Clearing
House (PCH) about IXP IP addresses of BGP routers, IXP members, and IXP
prefixes. We show that the used data are both rich, i.e., we find 12,716 IP
addresses of BGP routers in 460 IXPs, and mostly accurate, i.e., our validation
shows 92-93% accuracy. In addition, 78.2% of the detected IXPs in our data are
based on multiple diverse evidence and therefore help have higher confidence on
the detected IXPs than when relying solely on IXP prefixes. To demonstrate the
utility of our tool, we use it to show that one out of five paths in our data
cross an IXP and that paths do not normally cross more than a single IXP, as it
is expected based on the valley-free model about Internet policies.
Furthermore, although the top IXPs both in terms of paths and members are
located in Europe, US IXPs attract many more paths than their number of members
indicates.
