Make sure kernel version is 4.9 or newer:
uname -r
Install Hardware Enablement Stack (HWE) to update kernel automaticly:
apt install --install-recommends linux-generic-hwe-16.04
-
Enable bbr:
modprobe tcp_bbr echo "tcp_bbr" >> /etc/modules-load.d/modules.conf echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf sysctl -p
-
Check if bbr is enabled:
sysctl net.ipv4.tcp_available_congestion_control sysctl net.ipv4.tcp_congestion_control lsmod | grep bbr

Need reboot after Step 1:
rebootorsudo reboot
I don't think that's needed after sysctl -p
How can I enable other variants of BBR like Tsunami or BBR+ ?
