A network diagnosis and measurement tool
Paris Traceroute is a fundamental upgrade to the standard Traceroute tool that exists on all of the major operating systems. Standard Traceroute was not designed to take into account the presence of load balancing routers, which are widely deployed in today’s Internet, both at the core and at its edges. As a result, standard Traceroute is not aware that there are often multiple paths between a source and a destination in the Internet: the paths will split at a load balancing router at one point along the route and then reconverge some hops later. Standard traceroute is incapable of furnishing this information to its users and instead reports what it states to be a single path but is instead a confusing mixture of pieces of multiple paths. Paris Traceroute is aware of the multiple paths and can report on any single one of them accurately, as well as on all of them.
