How can I deploy TCP_BBR on my linode?
My linode is using CentOS 6.8, in order to deploy BBR, I followed some instructions like:
[http://itfashion4u.blogspot.com/2017/09/activate-tcp-bbr-on-linode-vps.html]
There is this step almost in every instruction:
lsmod | grep bbr
They said this command should return something included "tcp_bbr", but I always got nothing in return.
And I didn't feel any change about the transfer speed on the linode. So I don't know if BBR worked, am I doing it right?

If I run the uname command, I can see the kernel displayed.
$ uname -r

If you uname -r, what do you see?
The guide you shared appears to be for an Ubuntu system as I was unsuccessful in installing the kernel with dpkg.
We do have a guide that goes over this in detail, here:
Particularly, the portion that goes into configuring the kernel may be the steps you are missing.
