cake made it into any CPE and home routers or deployment, down under?<br>
Or is it all policers?<br>
<br>
I remember Mark Nottingham ran cake for a while, then ran a heat gun<br>
on edgerouter X he was using... (it was a hilarious picture, I don´t<br>
remember what forum it was on?)<br>
<br>
B) For the last 9 months I have been helping out the <a href="http://libreqos.io" rel="noreferrer noreferrer" target="_blank">libreqos.io</a><br>
project leverage xdp, ebpf, rust, and cake (in diffserv4 mode) to<br>
build a high performance transparent bridge to better shape traffic.<br>
<br>
We have got it to where it can push 25Gbits at about 40% of cpu on 16<br>
cores on a xeon gold for about 10k ISP subscribrs on various plans. We<br>
are now in rc2 on the v1.4 release, which has a bunch more speedups<br>
and analytical tools. Another cool feature in it is "on a stick" mode<br>
where it can go inband on a single port and do the magic across vlans.<br>
<br>
I (wearing my scientist hat) am very interested in evaluating network<br>
behaviors and performance at a mixture of shorter and longer RTTs and<br>
fiber vs wireless transports. Is there anyone down there willing to<br>
put this inline on their network? It´s pretty stable code, now, I<br>
think... I'm pretty sure... and takes about 20 minutes to get setup<br>
(most of which is compiling the rust)<br>

<a href="https://github.com/LibreQoE/LibreQoS/wiki/v1.4" rel="noreferrer noreferrer" target="_blank">https://github.com/LibreQoE/LibreQoS/wiki/v1.4</a> has the install<br>
instructions (for the truly daring there is the "heimdall" branch where<br>
the post 1.4 work is going) and we did a podcast about it here:<br>

thx for any help you can offer!<br>

I keep wondering if sqrt(flows) bdp is correct:<br>
