Some ISPs might be throttling P2P traffic with out letting the users know about these practices. There are not many good tools available to test ISPs behavior and if they are throttling some kind of traffic. Google along with New America Foundation’s Open Technology Institute, the PlanetLab Consortium, and researchers came up with Measurement Lab, an open platform for researchers and also a set of tools for the average web user.
Through Measurement Labs (M-Labs) Google will provide researchers with 36 servers in 12 locations in the US and Europe, these servers will provide the accuracy and scalability for the tools researchers already working, like testing the connection speeds, ISP throttling behavior, various diagnostic tests etc. M-Labs will serve as a community platform, the data collected through M-Labs will be given back to the public so that others can build on the work.
For users who want to test their connections there are 3 tools available right now. Access all the tools from Measurement Labs
Network Diagnostic Tool
As the name suggests Network Diagnostic Tool (NDT) provides speed and diagnostic test. Not only upload and download speeds but NDT also shows what if there are any problems like configuration or network problems.
Glasnost allows you to check if your ISP is throttling your bittorrent traffc. Also see Switzerland, a tool from EFF to checking ISP bittorrent throttling.
Network Path and Application Diagnosis (NPAD)
“NPAD diagnoses some of the common problems effecting the last network mile and end-users’ systems. These are the most common causes of all performance problems on wide area network paths.”
