This sounds amazing. Poor TCP congestion control algorithms have long been the limiting factor of today's broadband connections never reaching their potential speed. It looks like this was already patched into the kernel for those interested: <a href="https://lwn.net/Articles/701149/" rel="nofollow">https://lwn.net/Articles/701149/</a> - can't wait to experiment with this!
This is a delay-based scheme; it is unlikely to work well if competing with a drop-based aggressive scheme like TCP Cubic.<p>As a result, while BBR is fantastic for deployment e.g. in Google's private WAN, it's unclear how well it would do in the Internet, and initial experiments are not promising [1].<p>[1] <a href="http://www.ietf.org/mail-archive/web/tsvwg/current/msg14798.html" rel="nofollow">http://www.ietf.org/mail-archive/web/tsvwg/current/msg14798....</a>
