Putting Your ISP to the Test with M-Lab

mlablogoGoogle has partnered with Open Technology Institute, PlanetLab Consortium and other academic researchers to release tools designed for measuring the performance of your internet connection, developed under the Measurement Lab.

  • Network Diagnostic Tool (NDT) – measures your broadband speeds and identifies common network problems
  • Glasnost – tests if your ISP is throttling or blocking BitTorrent traffic
  • Network Path and Application Diagnosis (NPAD) – diagnoses some of the common problems effecting the last network mile and end-users’ systems
  • DiffProbe (coming soon) – tests to see if your ISP is prioritizing or degrading certain traffic (traffic shaping)
  • NANO (coming soon) – attempts to detect whether an ISP is degrading the performance of a certain subset of users, applications, or destinations

In the US, Comcast has in the past run into problems with the FCC for content discrimination, particularly of P2P streams. Cox is also not coy about it traffic shaping policies.

These tools are essential to helping you figure out if you are getting the internet service from your provider that you paid for.
