Ultra Ethernet Consortium Publishes 1.0 Specification, Readies Ethernet For HPC AI
Networkworld, Wednesday, June 11th, 2025
The UEC 1.0 specification includes a modern RDMA approach, new transport protocols, and congestion control mechanisms designed for AI and HPC requirements.
In mid-2023, a host of big name networking vendors including Cisco, Arista, HPE and Intel got together to form the Ultra Ethernet Consortium (UEC). The goal is to make Ethernet better for the needs of AI and high-performance computing (HPC).
Now, nearly two years later, the UEC is delivering on its initial promise with the release of the first UEC 1.0 specification. The specification details enhancements to Ethernet that improve low-latency transport in high-throughput networking deployments. It includes a modern Remote Direct Memory Access (RDMA) approach, direct memory access implementations, transport protocols, and congestion control mechanisms.
