[Starlink] How to help?

Hello,

I've had a Starlink (the round version 1) for around a year and was
thinking about bufferbloat yesterday and just found your mailing list. I
just started looking at the archives but I'm gathering that you are looking
for people to test things and am wondering what I can do to help?

I have used flent a little before, and only know the basics, but I can run
tests if you give me direction for what you need.

I am not using the provided Starlink router but instead the dish is
connected directly to my EdgeRouter X which is running the 1.10 series
EdgeRouter firmware with Cake from
https://community.ui.com/questions/Cake-compiled-for-the-EdgeRouter-devices/fc1ff27c-f321-4344-8737-fcc755cae8a2

I see a link to running CAKE with adaptive bandwidth:
https://forum.openwrt.org/t/cake-w-adaptive-bandwidth/108848

But this is running OpenWrt. I know OpenWrt can run on the EdgeRouter X but
I can't spend the level of time to flash the router that it would probably
need right now. Do you know if that script would be able to run on the
version of Cake that I currently have running on the EdgeRouter X? Or have
necessary improvements been made to Cake that my version wouldn't have?

Thanks,

Nick

We had a ton of email bounce last week.

So far as I know the edgerouter version of cake is pretty current.

the script requires some things about timings that egerouter
may not have.

At the moment...

I am mostly looking to get baseline tests from various vantage points,
w/o sqm. Starlink throughput is varying wildly
from multiple locations. The latency seems to vary as a function of a
fixed length fifo. Increasingly seems to vary at peak hours.
Running tests for 300 sec to be sure to see at least one sat change.

Script:

#!/bin/bash
T=dishy-nick # a unique name for your site, + options like sqm on or off.
# other servers are in ontario, de, atlanta, mumbai,london - if the
lasers go up testing those become interesting
# pick 2 close ones
for S in fremont.starlink.taht.net dallas.starlink.taht.net
do
flent -t $T --step-size=.05 --socket-stats -l 300 -H $S rrul_be
flent -t $T --step-size=.05 --socket-stats -l 300 -H $S rrul
for i in 1 4 16
do
flent -t $T-$i  --step-size=.05 --socket-stats -l 300
--te=upload_streams=$i -H $S  tcp_nup
flent -t $T-$i --step-size=.05 --socket-stats -l 300
--te=download_streams=$i -H $S tcp_ndown
done
done

# there's an interesting rtt_fair test here, keep these for a baseline
worlwide measurement

flent -x --socket-stats --step-size=.05 -H de.starlink.taht.net -H
london.starlink.taht.net -H singapore.starlink.taht.net -H
fremont.starlink.taht.net -t $T rtt_fair4be
