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

[Dave Taht <dave.taht@gmail.com>]

Perhaps it's obvious to the authors that FQ opens up new possibilities
for delay based convergence. Otherwise, pretty good:

"We prove that when two flows using the same CCA share a bottleneck
link, if the non-congestive delay variations exceed double the
difference between the maximum and minimum queueing delay at
equilibrium, then there are patterns of non-congestive delay where one
flow will get arbitrarily low throughput compared to the other. Our
theorem shows that CCAs have
to choose at most two out of three properties: high through put,
convergence to a small and bounded delay range, and no starvation."
