<div>I plan to do a follow-up to the paper you linked to below to give some of the details. Should be ready before IETF89.</div>

Thanks for the information. I'd be interested in why you have chosen<br>
PIE, e.g., instead of sfq-CoDel. Any pointers to evaluation<br>
reports/results? Last time I saw a presentation on this it seemed<br>
that CoDel was performing quite well.<br>

</div>
<div>I think this cablelabs report makes the argument for PIE:</div>
<div><br>
</div>
<div><a href="http://www.cablelabs.com/downloads/pubs/Active_Queue_Management_Algorithms_DOCSIS_3_0.pdf">http://www.cablelabs.com/downloads/pubs/Active_Queue_Management_Algorithms_DOCSIS_3_0.pdf</a></div>
<div><br>
</div>
<div>Mostly in that in the heavy traffic scenarios, PIE outperforms sfq_codel, and in general is a tad bit better than codel, with a simpler implementation (I think). Although I think I take issue with the "heavy traffic" model, but I'm guessing (hoping) that
it's based on surveys of customer traffic. 60-110 upstream flows seems like a lot. But it's based around a heavy use of BitTorrent, so maybe that's reasonable for some people.</div>
<div><br>
</div>
<div>But in all other cases, sfq really blows the doors off of the others.</div>
