Internet Measurement Tests
M-Lab hosts a number of measurement tests, allowing you to check for everything from network speed and latency to blocking and throttling. Explore them below, and run a test to learn more about your connection.
- All data collected will be made publicly available, including IP addresses.
- All tests are open source and created by researchers.
PerformancePerformance tests measure basic and advanced performance characteristics of your network, such as speed, latency, jitter, and much more.
NDT (Network Diagnostic Test)
Tests your connection speed, and provides a sophisticated diagnosis of problems limiting speed.
NPAD (Network Path & Application Diagnostics)
Diagnoses common problems that impact last-mile broadband networks.
Performs periodic tests to measure network performance and traffic throttling.
Tested the available bandwidth of an Internet connection until it was decommissioned from the M-Lab platform on 12/21/2012. However, the data and source code are still available.
Allows you to apply to host a home router that also tests network performance over time.
Collects statistics about the TCP connections running on the M-Lab platform.
