Be interesting to see how this stacks up to the dominant protocol in supercomputers/ai clusters : Infiniband.

AFAICT this is very much about handling unreliable links and congestion control.

Infiniband instead makes the sides bargain to avoid packet loss, while the medium is supposed to be reliable.

As mentioned in README, this was submitted to the larger Ultra Ethernet consortium for consideration:

> Deliver an Ethernet based open, interoperable, high performance, full-communications stack architecture to meet the growing network demands of AI & HPC at scale

I thought infiniband was more expensive and that even AI where bandwidth is super important was trying to get away from it towards cheaper options.
