TCP acceleration: BBR enhanced version for Debian/Ubuntu

Compared with Ruisu, BBR does not occupy resources and has better network optimization. The modified version below is more suitable for the network environment in mainland China than the original version. Some merchants' VPS may be unable to start the system after changing the kernel, so please be sure to back up important data before running the script! !

1. BBR Magic Version 1 works perfectly on Debian8, Debian9, and Ubuntu16.04. Under ssh, root user:

wget --no-check-certificate -qO 'BBR.sh' 'https://us.com/wp-content/uploads/2017/08/BBR.sh' && chmod a+x BBR.sh && bash BBR. sh -f

Script description: The module will be recompiled during execution. The module is automatically loaded at boot by default. Module name: tcp_bbr_powered You can use the modprobe tcp_bbr_powered command to load the module. You can execute lsmod |grep 'bbr_powered' and the result is not empty, then the module is loaded successfully. You can execute sysctl -w net.ipv4.tcp_congestion_control=bbr_powered to use this module. The above is just an explanation, just use the one-click script.
