AI-Optimized Ethernet Switching Fabric (RoCEv2, lossless) — data-center switch / NIC / fabric IP
**Companies committing:** meta-platforms, arista-networks, cisco-systems, juniper-networks, cornelis-networks, hpe, intel-corporation, enfabrica, astera-labs.
**Opportunity:** Hyperscalers want to break NVIDIA/Mellanox InfiniBand lock-in on GPU back-end fabrics; RoCEv2 + UEC-style lossless Ethernet is the consensus alternative but requires retimers, congestion control, and NCCL tuning to match IB.
Every Tier-1 (Cisco, Arista, Juniper, HPE, Meta) and an aggressive challenger set (Enfabrica SuperNIC, Cornelis Omni-Path, Astera Ethernet retimers) is hiring PM/TPM/perf-eng for the same problem. The race is product-defined: who delivers a turnkey 'Ethernet for AI' SKU first. Bottleneck is collective-comm/NCCL benchmarking — not silicon.
_Evidence caveat: A4 evidence is governance, not revenue; no A2/A5 hit._
