We might be talking a lot more about PRKI as it becomes compulsory,
maybe 400G transit links will start being standard across the

maybe a whole new routing protocol will be introduced and rapidly gain
popularity.
One interesting observation is that QUIC has the potential to open the
floodgates for new purpose built transport protocols for things other
than http that have their own requirements. It also shows that it can
navigate the problem of pleading kernel code and firewalls that block
unknown (it it) IP protocol numbers. It's my guess that those were what
really sunk SCTP. Another thing that is coming up is that with
increasingly high bandwidth, the TCP checksum is showing its age and
we'd probably like to leverage crypto-grade hashes instead of being at
the mercy of a 40 year old algorithm.
