Hi Mohit,

Thanks for doing the comparison!

As for "any other material related to this?" I'v= e had a dig around, and there is not a lot. Rasool (the FreeBSD fq-pie author) did write up a university tech report in April 2016, "Dummyne= t AQM v0.2 =E2=80=93 CoDel, FQ-CoDel, PIE and FQ-PIE for FreeBSD=E2= =80=99s ipfw/dummynet framework" (wayback machine link). There's also a small mention in an LCN 2017 paper titled &quo= t;Characterising LEDBAT Performance Through Bottlenecks Using PIE, FQ-CoDel and FQ-PIE Active Queue Management" (ieee link, author preprint). Hope these are of some (historical) interest to your I-D (and the wider bufferbloat mailing list, too).

Thanks for sharing these links. I will go th= rough the material.
=C2=A0
I'm unaware of any production deployment of FreeBSD's fq-pie.

Thanks for letting me know.=C2=A0<= /div>

I presented the FQ-PIE ID in the recently conclude= d IETF at tsvwg. I believe there was interest in the group to have a specif= ication for FQ-PIE.

It would be great if you could= share your views on the tsvwg mailing list when you get a chance.

Thanks and Regards,
Mohit P. Tahiliani
