TCP Acceleration: BBR Enhanced Edition for Debian/Ubuntu

Compared with Ruisu, BBR does not occupy resources and has better network optimization. The following revised version is more suitable for domestic network environment than the original version.
Some merchants' VPS may encounter the situation where the system cannot be started after changing the kernel, so please be sure to back up important data before running the script! !

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

 wget --no-check-certificate -qO 'BBR.sh' 'https://zhujiwiki.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
The module can be loaded using the modprobe tcp_bbr_powered command.
Execute lsmod |grep 'bbr_powered'
If the result is not empty, the module is loaded successfully and you can execute sysctl -w net.ipv4.tcp_congestion_control=bbr_powered to use this module.
The above is just an explanation, you can use the one-key script directly.
