May I ask a stupid question = where could I find the TCP BBR patches :P=20 =46rom the FreeBSD Transport DevSubmit page, I knew that Randall Stewart = is the main contributor for TCP BBR task, and found the code changes may = be ready to get in. > Michael asks about how well we can pull the pacer our of the Rack/BBR = code and use it generally. rrs@ thinks that is already done. rrs@ says = there are 3 steps to getting this in,=20 > - Get in the Black Box=20 > - Get in the Pacer which no one uses until Rack/BBR is in.=20 > - Place Rack and BBR into the tree. I have searched the keyword =A1=B0BBR=A1=B1 on = https://reviews.freebsd.org , but I only = got few related documents, haven=A1=AFt found the source code change = about the TCP BBR: - D11086 ("Enable the ability to load multiple versions of the same = TCP stack=A1=B1) document.=20 - D11085 (=A1=B0TCP Blackbox Recorder") document I=A1=AFm planing to transplant the BBR congestion control algorithm for = FreeBSD SCTP network protocol in our project, so it would be really = great if I could find a BBR code base on FreeBSD. Any help would be = greatly appreciated :-D Thanks a lot, - Kuankuan=
