Maybe suggest using BBR congestion control? #22

Open ivanbaldo opened 7 years ago

ivanbaldo commented 7 years ago

For kernel >= 4.9 maybe it should be suggested to add this in sysctl: net.ipv4.tcp_congestion_control = bbr And this in /etc/modules: tcp_bbr Maybe I am wrong though... but if thats the case, then it could be mentioned in the webpage why I am wrong so others don't ask themselves this same question. Thanks a lot!

I don't regard BBR as baked enough to recommend.

Thanks a lot for your answer Dave! Now more than two and a half years later, whats your opinion on using BBR? BTW I been using it together with fq_codel and ECN=1 since then at home and one of my customers, didn't notice any problems so far... (of course this is just my case and I am not as expert as you, just comenting).

Ultimately, ecn or no, BBR will construct a good model of the path, and fq_codel garuntees that that is, indeed a good model.

That said, I'd really like to see RFC3168-like behavior enter bbr.
