At Meta's scale — clusters growing to over a million accelerators across regions — the network is in the critical path of every AI training step, and traditional RDMA was never built for it.
MetaRoCE is Meta's clean-sheet RDMA transport: a multipath, out-of-order, receiver-driven protocol that treats Ethernet as inherently lossy and pushes all intelligence into the NIC. By shifting intelligence to the edge, the transport decouples from topology — enabling TCO-optimized multiplane FPF topologies with frictionless application adoption on commodity Ethernet.
This talk covers MetaRoCE's core mechanisms and Meta's commitment to open standards, including a companion conformance suite developed with Keysight that validates implementations from software reference through hardware emulation to production silicon.
Meta is opening MetaRoCE to the industry and inviting broader collaboration to establish it as the ubiquitous RDMA transport for AI-scale networks.
