[Starlink] Re: Amazon Leo announcing up to 1 Gbps (DOWN) and 400 Mbps (UP)

[Frantisek Borsik <frantisek.borsik@gmail.com>]

I can't imagine a situation in which Amazon Leo - without using CAKE or
FQ-CoDel - would get good results, as Starlink didn't without FQ-CoDel
Hope that they will talk to us, and get help. Sadly, there is no Dave Taht
here anymore, to chase them for the good of their users :(

Improvements to CAKE are happening; MQ-CAKE (from Toke), some other good
options are raising, algorithms like FQ-PIE and PURPE CAKE, improvements
like xTCP2, XDP2: I will be talking about it at
https://understandinglatency.com - register, if you didn't, yet.

All the best,

Frank
