Measurement Lab Launches New Global Data Visualization Tools
The Measurement Lab (M-Lab) global measurement platform contains the largest collection of open internet performance data on the planet. Hundreds of thousands of people (and rising everyday!) test their internet connections on M-Lab and provide that data to the public domain for research, analysis and advocacy. As a consortium of research, industry, and public-interest partners, M-Lab is dedicated to providing an ecosystem for the open, verifiable measurement of global network performance. With an extensive library of data dating back to 2009, M-Lab has over 5 petabytes of information about quality of experience on the internet contributed by people like you.

What is TCP? Since the beginning of the its existence, the internet has expanded in scope, traffic, content, and a myriad of other ways. The protocols that make up the internet’s backbone have mostly remained the same since they were developed in the 1980s. The Transmission Control Protocol (TCP) was one of the first networking protocols defined during the internet’s development, and specifies how data should be transmitted and received.
