Reverse Traceroute - Towards standards-based path visibility
The network we envision for MAVERIC is characterized by dynamic changes. In particular, the backhaul connectivity can be volatile, change over time and multiple technologies are used to connect the RAN to the wider internet. In such dynamic settings, visibility into the current state of the network is important. Therefore, we have defined and implemented a reverse traceroute mechanism, that helps us with identifying potential problems in the network beyond what is available today. In order to have a broader availability of this reverse traceroute facility, we have contributed our design to the IETF. You can read up on our protocol design here.
