<div class="moz-cite-prefix">Hi Mohit,<br>
<br>
I wonder what you think of the fq-pie developed for FreeBSD back
in 2015 and merged in May 2016? (commit <a
href="https://reviews.freebsd.org/rS300779">here</a>.) It has
been too long since I last looked, so would love your thoughts on
how it aligns (or doesn't) with <a
href="https://datatracker.ietf.org/doc/draft-tahiliani-tsvwg-fq-pie/"

<div dir="ltr">Hi all,<br>
<br>
I have been working on an Internet Draft on Flow Queue PIE
(FQ-PIE) [<a
href="https://datatracker.ietf.org/doc/draft-tahiliani-tsvwg-fq-pie/"
moz-do-not-send="true" class="moz-txt-link-freetext">https://datatracker.ietf.org/doc/draft-tahiliani-tsvwg-fq-pie/</a>],
and recently submitted a revised version.<br>
<br>
It has been incorporated into the mainline Linux kernel as a
queuing discipline (qdisc). Additionally, an implementation of
FQ-PIE is available in the ns-3 network simulator.<br>
<br>
If you have any suggestions or feedback, please let me know.<br>
<br>
Thanks and Regards,<br>
Mohit P. Tahiliani<br>

Abstract:<br>
<br>
This document presents Flow Queue Proportional Integral
controller<br>
Enhanced (FQ-PIE), a hybrid packet scheduler and Active
Queue<br>
Management (AQM) algorithm to isolate flows and tackle the
problem of<br>
bufferbloat. FQ-PIE uses hashing to classify incoming
packets into<br>
different queues and provide flow isolation. Packets are
dequeued by<br>
using a variant of the round robin scheduler. Each such
flow is<br>
managed by the PIE algorithm to maintain high link
utilization while<br>
controlling the queue delay to a target value.<br>
