Interesting article from MIT:
https://news.mit.edu/2022/algorithm-computer-network-bandwidth-0804
The paper can be found on Venkat Arun's website:
https://people.csail.mit.edu/venkatar/
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").
Thoughts?
