Is there a way to track BBR internals on a running system?
Yes, there is a tcp logging function that can be used to turn on things. The other relevant question in this are: 1) What is the RTT 2) Do you know your bottleneck router buffer size 3) What are the rwnd’s in play here. There are known issues with BBR when it faces a high BDP (lots of buffers), new-reno or cubic will do better. One other thing is if you are running from a web browser (like we do at NF) then simply setting default sysctl works but you have to restart the web browser if its running. If its just a simpler set sysctl start-perf Then that should work. > 2. Is "sysctl -w net.inet.tcp.functions_default=bbr" sufficient to turn BBR > on? > See above. While the iperf is running you can do sysctl net.inet.tcp.functions_available and you should see a count by bbr showing its being used.
