From 2017 FYI:

"This Internet-Draft will expire on September 14, 2017."

Appears it didn't progress after that either - https://datatracker.ietf.org/doc/draft-looney-tcpm-64-bit-se...

The claim made here is that at 100GbE the sequence numbers wrap in milliseconds. That number seems right (source: vibes).

Why isn’t this a serious problem then? I’d love a networking expert to chime in.

Is it that high bandwidth links also have very low packet error rates?

Or is it that individual TCP flows rarely saturate the link? (Because of congestion control, lower end to end throughput, sharing links, or some other reason?)
