measurement-lab.ndt_raw.paris1_legacy? And also, could anyone tell me the meaning of some information in the traceroute records from paris-traceroute archive(https://console.cloud.google.com/storage/browser/archive-measurement-lab/paris-traceroute;tab=objects?prefix=&forceOnObjectsSortingFiltering=false) . For instance, what does P(6, 6) mean in the attached traceroute record below? What does "algo exhaustive" mean? I've tried the paris-traceroute but didn't get the P(x, x) in the output, and the option --algorithm doesn’t support exhaustive now.
