The Internet's congestion control landscape is
evolving. Since being first introduced on 2016,
BBR has been adopted by websites on the Internet
at an unprecedented rate. In this study, we aimed
to measure and identify the congestion control
algorithms deployed by the 20,000 most popular
websites on the Internet. Our results show that
in three short years since first being introduced
BBR has been adopted by about 18% of the websites
and is estimated to command about 40% of the
downstream traffic.
