If you're flexible enough to forgo UDP/IP, why not use infiniband instead of ethernet? That gets rid of all the complexity you mentioned but still gives you ordered streams

I agree, it's hard to see what real world use case would benefit from dumping UDP/IP while holding on to Ethernet, and not moving over to an Infiniband or similar solution. That also can't be satisfied by one of the existing specialized solutions that another user mentioned, such as EtherCAT.

Infiniband is basically a nVidia monopoly since they bought Mellanox, and the hyperscalers who already chafe at nVidia's GPU pricing power don't like it one bit, which is why they are working so hard on getting rid of it.

I don't understand enough about niche high-performance interconnects to know if CXL is a viable alternative for Infiniband where Ethernet-based solutions have too much latency.
