Debian開啟BBR加速

-------------------------

内核檢查

uname -r

返回的内核 6.12.63+deb13-cloud-amd64

開啟BBR，在 /etc/sysctl.d/ 建立一個設定檔，專門給BBR用

vi /etc/sysctl.d/99-bbr.conf

複製貼上這兩行

net.core.default_qdisc = fq

net.ipv4.tcp_congestion_control = bbr

ESC 儲存並離開

:wq

重開機

reboot

----------------------

測試是否開啟BBR

----------------------

敲入

sysctl net.ipv4.tcp_congestion_control

應該看到

net.ipv4.tcp_congestion_control = bbr

確認核心支援BBR，敲入

sysctl net.ipv4.tcp_available_congestion_control

應包含 bbr

確認qdisc，敲入

sysctl net.core.default_qdisc

結果應是 fq

說明BBR已啟動
