We've had a good chat or two on this subject already Dave :), chipping in my 2c / support here:
LibreQOS is already a part of a project that I am working on at the moment (pending some more deliveries of parts), so I'm hoping to get some testing done myself soon(tm) and be able to share some results with Dave after pushing it with the right hardware. It'd be great if others could also pickup LibreQoS and test it for their own requirements too if you can find the time - maybe we'll even end up with another interesting AusNOG talk about open-source network technology this year, who knows :) For the unaware - LibreQOS is tied to bufferbloat.net, cerowrt, etc, all of which Dave is heavily involved with. So definitely someone to talk to and a project to checkout if you've been following / are interested in AQM QOS mechanisms like CoDeL, CAKE, etc and the general fun around managing buffer bloat. - Jacob Bisby -----Original Message----- From: AusNOG <ausnog-boun...@lists.ausnog.net> On Behalf Of Dave Taht Sent: Tuesday, March 14, 2023 6:42 PM To: <ausnog@lists.ausnog.net> <ausnog@lists.ausnog.net>; Mark Nottingham <m...@mnot.net> Subject: [AusNOG] fq_codel/cake/libreqos beta testers wanted A) I have always been curious to what extent, if any, fq_codel, or cake made it into any CPE and home routers or deployment, down under? Or is it all policers? I remember Mark Nottingham ran cake for a while, then ran a heat gun on edgerouter X he was using... (it was a hilarious picture, I don´t remember what forum it was on?) B) For the last 9 months I have been helping out the libreqos.io project leverage xdp, ebpf, rust, and cake (in diffserv4 mode) to build a high performance transparent bridge to better shape traffic. We have got it to where it can push 25Gbits at about 40% of cpu on 16 cores on a xeon gold for about 10k ISP subscribrs on various plans. We are now in rc2 on the v1.4 release, which has a bunch more speedups and analytical tools. Another cool feature in it is "on a stick" mode where it can go inband on a single port and do the magic across vlans. I (wearing my scientist hat) am very interested in evaluating network behaviors and performance at a mixture of shorter and longer RTTs and fiber vs wireless transports. Is there anyone down there willing to put this inline on their network? It´s pretty stable code, now, I think... I'm pretty sure... and takes about 20 minutes to get setup (most of which is compiling the rust) https://github.com/LibreQoE/LibreQoS/wiki/v1.4 has the install instructions (for the truly daring there is the "heimdall" branch where the post 1.4 work is going) and we did a podcast about it here: https://packetpushers.net/podcast/heavy-networking-666-improving-quality-of-experience-with-libreqos/ thx for any help you can offer! -- I keep wondering if sqrt(flows) bdp is correct: https://blog.cerowrt.org/post/juniper/ Dave Täht CEO, TekLibre, LLC _______________________________________________ AusNOG mailing list AusNOG@lists.ausnog.net https://lists.ausnog.net/mailman/listinfo/ausnog _______________________________________________ AusNOG mailing list AusNOG@lists.ausnog.net https://lists.ausnog.net/mailman/listinfo/ausnog
