Overview

M-Lab publishes its test data in two forms:

  • Google Cloud Storage
  • Google BigQuery
    • M-Lab parses data for a subset of its tools and publishes the data on BigQuery so that users can run SQL queries on the data.
    • See M-Lab BigQuery QuickStart for more information.

There is typically at least a 24-hour delay between data collection and data publication.

Active Tests

  • M-Lab Collectd
    • mlab-collectd is a monitoring tool for M-Lab slices, which collects resource utilization information about all M-Lab servers.
    • More information is available on Github.
  • Neubot
    • Neubot measures the Internet in order to gather data useful to study broadband performance, network neutrality, and Internet censorship.
    • More information is available at Nexa Center and Github.
  • NDT
    • Network Diagnostic Tool (NDT) measures characteristics of a TCP connection under heavy load.
    • More information is available at Internet2 and Github.
  • NPAD
    • Network Path and Application Diagnosis (NPAD) diagnoses issues in a network path that can degrade network performance.
    • More information is available at UCAR and Github.
  • OONI
    • OONI measures censorship, surveillance, and traffic manipulation on the Internet.
    • More information is available at OONI
  • Paris Traceroute
    • Paris Traceroute maps network topology between two points on the Internet.
    • More information is available at Paris Traceroute
  • SideStream
    • SideStream collects TCP state information about completed TCP connections on a system.
    • More information is available on Github.

Inactive Tests

  • Glasnost (deprecated)
    • Glasnost detects prioritization or censorship of network traffic.
    • More information is available at MPI SWS and Github.
  • pathload2 (deprecated)
    • M-Lab no longer supports this tool, but its archived data are available on GCS. For similar measurements with a current and supported tool, see NDT.
    • Pathload2 measures the available bandwidth of an Internet connection.
    • More information is available at https://code.google.com/p/pathload2-gatech/.
  • ShaperProbe (deprecated)
    • M-Lab no longer supports this tool, but its archived data are available on GCS.
    • ShaperProbe detects prioritization of network traffic.
    • More information is available at ShaperProbe.
