Measurement Lab (M-Lab), an open platform for broadband measurement tools now has more than 300 terabytes of data from over half a billion tests.
M-Lab tools help an individual understand the performance of one’s own broadband connection, but making sense of that much data in the aggregate is more complicated. Google with M-Lab, have now developed a set of maps to help investigate such a huge dataset using Google’s Public Data Explorer.
The maps are built entirely on open data collected by Network Diagnostic Tool (NDT), an open source tool by Internet2. The visualizations show measured median upload and download speeds as measured by M-Lab tools across the US, Europe, and Australia, and you can drill down to city-level aggregates. You can also view to what extent speeds are limited by problems with users’ network connections or with their computers (or other devices).
On Mar 23, the Open Technology Initiative will be hosting a panel discussion on M-Lab in Washington, D.C. In a keynote, Vint Cerf will explain how M-Lab is helping analyze broadband performance and promote good science. For those who can’t attend in person, the event will be live-streamed via the web, starting at 10:30am, EST.
