[Starlink] SIGCOMM MIT paper: Starvation in e2e congestion control

[Hesham ElBakoury]

Hi David,

I think someone such as Professor Hari who got many awards including the 
sigcomm 2021 life-achievement award or his student Venkat need to be 
educated on Fair Queuing. There are many publications and text books 
which describe FQ. The results of this paper is for network paths that 
do not use FQ or ECN. Venkat/Hari can provide more details.

For the CAP theorem, do you think I can get C,A,P, if this is what I 
need ? if this is the case, then this theorem is wrong or has limited 
applicability, correct ?

Thanks

Hesham
