For every connection to an M-Lab server, the Traceroute core service collects network path information from our server back to the client IP that initiated the connection. M-Lab uses the Scamper traceroute tool provided by the Center for Applied Internet Data Analysis, CAIDA. The Scamper Traceroute tool has been in use by M-Lab since the fourth quarter of 2019 (Q42019). Prior to Q42019, M-Lab used the Paris Traceroute tool for this core service.

Traceroute Data in BigQuery

M-Lab parses all Traceroute data into BigQuery tables and views, and makes query access available for free by subscription to a Google Group. Find out more about how to get access on our BigQuery QuickStart page.

Traceroute Schema

Note: The tracerout schema has not yet been migrated to standard columns. Until that time, this schema should be considered temporary or unstable.
