Meta has announced MetaRoCE, an RDMA transport protocol designed for AI workloads on commodity Ethernet, with the specification, a reference implementation, and a compliance test suite to be released through the Open Compute Project. MetaRoCE moves network intelligence to the endpoint, supports native out-of-order delivery, multipathing, and loss tolerance without PFC. Meta says the protocol targets million-GPU-scale clusters and works with existing RDMA Verbs APIs without modification.
