<div class="moz-cite-prefix">Hi,<br>
<br>
nice demo.<br>
<br>
While I am not surprised about the good performance of QFQ+,<br>
I do not understand why DRR (I guess linux SFQ, i.e. per-flow
DRR+SQdrop)<br>
works so bad.<br>
<br>
If the two schedulers are serving the same kind of flow (IP
5-tuple) the level<br>
of protection to low rate (< fair rate) flows should be the
same (approx).<br>
<br>
Maybe Paolo said that in the talk and I might have missed
something.<br>
Is QFQ+ working on a different definition of flow than DRR?, and
is DRR Linux SFQ?<br>

Hi,<br>
I just uploaded the following 7-minute video showing the
QoS and the execution time of QFQ+, compared to those of
DRR:<br>
<a moz-do-not-send="true"
href="http://youtu.be/bG2ACt4na7A" target="_blank">http://youtu.be/bG2ACt4na7A</a><br>
<br>
I would like to advertise this video. If I may ask for
your help, do you think that linux-kernel, linux-net or
linux-netdev may be appropriate?<br>
Any other suggestion is more than welcome.<br>
<br>
Thanks,<br>
Paolo<br>
