CakeQOS Cake-autorate

Its been awhile since I messed with this again, written by @Lynx. Its really has came along ways and working nicely with starlink.

Yes cake-autorate has been stable for quite a while now. And it really works on Asus Merlin - see these stats based on a log file generated by @rlj2 on Asus Merlin using a Starlink connection:

The script needs updating · Issue #1 · LiveWire1968/Asus-cake-autorate

Hi, the script needs updating since its not working now

github.com

cake-autorate for sure works well for 4G and 5G variable rate connections, but the Starlink case is not certain at the moment - we do not have much data from Starlink connections and I have a feeling that Starlink are actively working on the latency issue. So more testing is needed for Starlink specifically.

A goal now is to extend the installer script of cake-autorate to include an option for installing on Asus Merlin routers. Looks like this should be fairly straightforward.

So more testing is needed for Starlink specifically.

Compared to 5G-FWA where both the cells and access terminals are static - starlink cells have variable latency as the birds fly overhead and handoff from one to another - so it adds another dimension...

Starlink does a good job of hiding that variable, but they can only do so much to mask that from the clients on the other side of the dish...

Yes true - we identified switching times at 15 second intervals as per: XX:12, XX:27, XX:42 and XX:57 - see discussion around here:

CAKE w/ Adaptive Bandwidth [October 2021 to September 2022]

No distraction at all - it seems this is all rather a challenge! Looking at the data sets here, are we really seeing spikes at the right times? Hard to say - maybe? That's going with these times: And just working with timestamp in the ping responses. So maybe we set CAKE rate to...

forum.openwrt.org

I put in some experimental code in cake-autorate to try to address that:

cake-autorate/cake-autorate.sh at 0db0b2ad17d76e2588468ab857e24fcc47b56b60 · lynxthecat/cake-autorate

Eliminate the excess latency and jitter terrorizing your 4G, 5G, LTE, Starlink or other variable rate connection! - lynxthecat/cake-autorate

github.com

And initial results seemed positive:

CAKE w/ Adaptive Bandwidth [October 2021 to September 2022]

Are we covering the switches? Here is RTT and seconds past the minute: Here is the familiar plot: Now with seconds past the minute scaled up so we can see on secondary axis: Here are the switches I think: So at least from this it looks like there are no major RTT spikes...

forum.openwrt.org

But a lot more testing is needed. I think an issue is that things work well enough with or without the experimental switching compensation.
If any Asus Merlin users with Starlink connections would like to test, we would really appreciate the data and feedback.

Hey @Lynx

I'm currently trying to install this on my RT-AC86U, but i'm totally clueless and new to this.

Can anyone guide me on how to install these files?

Is it through USB in the router?

Thanks for any help!

 

[L&LD]

Use Putty on your computer. Enable ssh on the router.

Hi there,

So basically i've installed the files to jffs/ scripts, right clicked each of them and enabled the X on permissions section? Is that right?

I'm not sure what "requires entware, bash iputils-ping fping installed" refers to.

How do I know it's installed properly, do I need to run the scripts through the router?

Apologies for any frustration but I am totally clueless with this stuff.

 

[L&LD]

Ignore the steps where it says to install amtm (already installed on current firmware).

Thanks, amtm and entware are all setup, not sure how to start the script on the router now though. Is there a command?

 

[Kiiran_B]

I need to start from the beginning here. Am I following the original install of auto rate then pasting the asus files over them?

you need to run these commands with ssh (putty)..
opkg install bash
opkg install iputils-ping
opkg install fping
opkg install git
opkg install git-http
git clone https://github.com/LiveWire1968/Asus-cake-autorate.git
cd Asus-cake-autorate, chmod +x *
cp * /jffs/scripts
echo /jffs/scripts/launcher.sh >> /jffs/scripts/post-mount

Then edit /jffs/scripts/config.primary.sh for changes.

echo /jffs/scripts/launcher.sh >> /jffs/scripts/service-event

What is the purpose of relaunching your script on ANY service event? Seems like overkill. What does it really depend on?

i just looked again, it will not start from services-start for some reason. post-mount maybe?

Is there a command to check if the script is alive and working?
