验证Google BBR开启和关闭

验证Google BBR是否开启

12345678910#先查看内核版本uname -a#再检查net的返回参数一般为:bbr cubic reno 或者 reno cubic bbrsysctl net.ipv4.tcp_congestion_control   #返回值:net.ipv4.tcp_congestion_control = bbrsysctl net.ipv4.tcp_congestion_control #返回值:net.core.default_qdisc = fqsysctl net.core.default_qdisc

关闭Google BBR

同理,关闭Google BBR,把对应参数改掉即可

1234567sudo vim /etc/sysctl.conf #用#注释掉:#net.core.default_qdisc = fq#net.ipv4.tcp_congestion_control = bbr sysctl -p
