"Where the !?*! are the packets going?”

Traceroute has been helping troubleshoot network issues since the late 80s. In that time, it has become one of the most used tools in Internet measurement and topology discovery. Here at Catchpoint we leverage Linux traceroute to perform measurements from nodes distributed all over the world. In order to do what we do, we've enhanced the Linux traceroute to add some useful and interesting capabilities, and made those changes publicly available. In this presentation we are going to have an overview of the enhancements we made to traceroute. These Improvements include support for QUIC, a new style of TCP traceroute called "InSession" aimed at bypassing firewalls, ECN bleaching detection, path MTU discovery speedup and many more. The presented enhancements are made open source with the hope that they can be helpful to the networking community.
