Re: [Cerowrt-devel] android, sqm-autorate and lte and videoconferencing
Whilst I understand it's not designed for High Bandwidth uplinks - how does it scale to 1 to 10Gbit symmetrical (or near symmetrical) uplinks ? One of the problems i've had with Cake is that it becomes CPU bound beyond around 3 or 4 gigabit.

Re: [Cerowrt-devel] android, sqm-autorate and lte and videoconferencing
Dear all, Thank you very much for the introduction Sebastian. To give some context, my wife and I relocated to the Scottish Highlands and now rely upon a 4G LTE connection for work and personal use through Vodafone UK. I have spent quite a lot of time working on this autorate problem and have tried to leverage Sebastian's expertise in this field as much as possible. I have tried to keep it as simple as possible with some rationale and objective criticism behind the major logic. I value feedback and criticism. I now use the bash implementation in my main branch on my RT3200 router as a service 24/7. I have rewritten it a few times and will do so again, or switch to another better approach if available. There have been a few ports of some of the earlier versions like this Golang version ( https://github.com/notsure2/cake-autorate).

Re: [Cerowrt-devel] android, sqm-autorate and lte and videoconferencing
Dear Dave, dear all please, let me introduce Andrew to this list, who is the driving force behind CAKE-autorate's design and implementation (which started from a more theoretical discussion in the OpenWrt forum before turning into something tangible). There are other alternative approaches for the rate-tracking problem many discussed in this longish forum thread: https://forum.openwrt.org/t/cake-w-adaptive-bandwidth/108848 (which is great as this occasionally leads to quite interesting discussion about how the different teams tackle common issues) but Andrew's autorate appears to the fastest moving with low software requirements (every router should run bash anyway ;) ).

[Cerowrt-devel] android, sqm-autorate and lte and videoconferencing
For the past several days, I have been very successfully using variants of the cake-autorate code to manage my connections on the boat, for which I use a tether to my laptop. https://github.com/lynxthecat/CAKE-autorate Although this test claims my link was inadequate for a good videoconference https://www.waveform.com/tools/bufferbloat?test-id=964831e5-30f9-4695-bfbd-b58da0a759f3 they have all been perfect (and that test was conducted during an actual zoom conference). The code does not grab as much bandwidth as it could, when available, but I'll settle for perfect videoconferencing. Anyway... what I used to do was attach the phone to a router shared boat-wide that did this stuff, but it would be nice to move the algorithm directly into an android. My hope is that more modern androids are running a recent enough kernel(?) to have cake, but it's been a long time since I built anything for android, and am wondering if there is a lte/5g tablet or phone or dedicated lte router "out there" that can be hacked on? -- I tried to build a better future, a few times: https://wayforward.archive.org/?site=https%3A%2F%2Fwww.icei.org Dave Täht CEO, TekLibre, LLC ___ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel
