OONI traceroute

The OONI probe traceroute is a multiprotocol multiport traceroute test. The goal is to detect protocol/port based biases by doing a traceroute with different protocols and different ports.

It detects the hop for every protocol/port pair in the same round to minimize the risk of encountering route changes over time. At every round we send packets with the same TTL, but with different protocol/port combinations and wait to get back the TTL exceeded for all the send packets. Then we increment the TTL by one.

TODO:

  • There is a bad bug that makes everything work badly with more than 2! port combinations. Hunt it down and kill it!

  • Collect the timestamp of the response by adding the IP_TIMESTAMP option. This will make the device sending back the TTL exceeded packet add the timestamp of when it got the expired packet.

  • Add IP flag to get the MPLS VRF number of the Hop (if it exists)

  • Activate IP option 7 record route

Sample output from a run (with only port 0 and 80):
