Technical Details
what runs on :4793UET uses UDP port 4793 for Ultra Ethernet transport traffic. UET datagrams carry the protocol's transport headers and payload over IP, with transport features intended for high-throughput, low-latency datacenter fabrics, including congestion and loss handling and support for multipath or packet-spraying deployments. It is not a TCP service and normally will not present an interactive application handshake; the exact exchange and framing depend on the UET implementation and its negotiated transport mode. This port is distinct from RoCEv2, which commonly uses UDP port 4791.

security overview
UET is intended for controlled datacenter networks, not direct exposure to the public internet. Internet-reachable implementations could be subjected to spoofed or malformed UDP traffic, resource-exhaustion attempts, and implementation vulnerabilities; apply fabric ACLs and restrict the port to trusted UET peers. UET transport itself should not be assumed to provide application-layer confidentiality or authentication.
