Linux打开TCP BBR拥塞控制算法

Posted 2020-10-10 blog of asml

要求内核为4.9以上,如果不是,请升级内核.

 

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
sysctl net.ipv4.tcp_available_congestion_control
sysctl net.ipv4.tcp_congestion_control

 

通过以下命令查询是否打开成功:

lsmod | grep bbr
