Introducing Measurement Lab
28 janvier 2009
When an Internet application doesn't work as expected or your connection seems flaky, how can you tell whether there is a problem caused by your broadband ISP, the application, your PC, or something else? It can be difficult for experts, let alone average Internet users, to address this sort of question today.
Last year we asked a small group of academics about ways to advance network research and provide users with tools to test their broadband connections. Today Google, the
New America Foundation
's Open Technology Institute, the
PlanetLab Consortium
, and academic researchers are taking the wraps off of
Measurement Lab
(M-Lab), an open platform that researchers can use to deploy Internet measurement tools.
Researchers are already developing tools that allow users to, among other things, measure the speed of their connection, run diagnostics, and attempt to discern if their ISP is blocking or throttling particular applications. These tools generate and send some data back-and-forth between the user's computer and a server elsewhere on the Internet. Unfortunately, researchers lack widely-distributed servers with ample connectivity. This poses a barrier to the accuracy and scalability of these tools. Researchers also have trouble sharing data with one another.
M-Lab aims to address these problems. Over the course of early 2009, Google will provide researchers with 36 servers in 12 locations in the U.S. and Europe. All data collected via M-Lab will be made publicly available for other researchers to build on. M-Lab is intended to be a truly community-based effort, and we welcome the support of other companies, institutions, researchers, and users that want to provide servers, tools, or other resources that can help the platform flourish.
Today, M-Lab is at the beginning of its development. To start,
three tools
running on servers near Google's headquarters are available to help users attempt to diagnose common problems that might impair their broadband speed, as well as determine whether BitTorrent is being blocked or throttled by their ISPs. These tools were created by the individual researchers who helped found M-Lab. By running these tools, users will get information about their connection and provide researchers with valuable aggregate data. Like M-Lab itself these tools are still in development, and they will only support a limited number of simultaneous users at this initial stage.
At Google, we care deeply about sustaining the Internet as an open platform for consumer choice and innovation. No matter your views on net neutrality and ISP network management practices, everyone can agree that Internet users deserve to be well-informed about what they're getting when they sign up for broadband, and
good data is the bedrock of sound policy
. Transparency has always been crucial to the success of the Internet, and, by advancing network research in this area, M-Lab aims to help sustain a healthy, innovative Internet.
