验证Google BBR开启和关闭

验证Google BBR是否开启

#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 bbr
sysctl net.ipv4.tcp_congestion_control	

#返回值：net.ipv4.tcp_congestion_control = bbr
sysctl net.ipv4.tcp_congestion_control

#返回值：net.core.default_qdisc = fq
sysctl net.core.default_qdisc

关闭Google BBR

同理，关闭Google BBR，把对应参数改掉即可

sudo vim /etc/sysctl.conf

#用#注释掉：
#net.core.default_qdisc = fq
#net.ipv4.tcp_congestion_control = bbr

sysctl -p
