[Make-wifi-fast] free.fr and fq_codel

[Valent Turkovic]

Hi,
I read on bufferbloat wiki [1] an interesting blurb:
"Free.fr has the first known large-scale fq_codel deployment, using
three bands of fq_codel for tiers of QoS. (it is also the largest ECN
enabled end-user deployment)."

I'm very interested in such examples as they offer a great wealth of
condensed knowledge. Does anyone know more? How is this configured
exactly? How are these tiers of QoS configured? What part of free.fr
network is discussed (access, backbone, something else?) ?

Thanks!

My understanding was that it was in use within their v6 freebox server:
https://www.freebox-v6.fr

Which is the DSL Modem/Router for the residence.  When I lived in Paris
(4-5 years ago), free.fr was my ISP.  I don't have details of the
deployment, except that it was very well done.  Using CeroWRT and the
qos_scripts I made only marginal improvements over their own configuration
(not enough to be worthwhile, honestly).  ~70ms ping times, regardless of
the load.  Virtually no bufferbloat.

My write-up (which is terrible, and naive, but I was still learning about
bufferbloat at the time), is here:

My current view is that all of the fiddling I did then was for naught.  No
real improvement over what they had on the wire.  And vastly better than
any other ISP I've seen (as you can see from the rest of the posts there).
