Yup!
My company just decided that routing fallbacks, like the ARPA NIMs had,
weren't necessary. Right after the Rogers BGP fiasco that cut off 50% of
Canada from the internet...
Bother!

"Flow control power is non-decentralizable" is from -- 1981? So we've
known for 40 years that TCP streams won't play nicely with each other
unless you shape them at the slower endpoint-- am I understanding that
correctly? But we keep trying anyway? :)

Main take-away (as I understand it) is something like "In real-world networks, jitter adds
noise to the end-to-end delay such that any algorithm trying to infer congestion from end-to-end
delay measurements will occasionally get it wrong and this can lead to starvation". Seems
related to Jaffe's work on network power (titled "Flow control power is
non-decentralizable").
Hasn't this been known for many years, as a consequence of experience with TCP
Vegas?

It seems like BBR developers thought they could do better. Unfortunately,
papers with negative
results never seem to get written or published ;-(
