How OpenAI’s MRC Protocol Redesigns Communication for 100,000‑GPU Clusters

OpenAI, together with AMD, Broadcom, Intel, Microsoft and Nvidia, introduced the Multipath Reliable Connection (MRC) protocol, which splits a single 800 Gb/s link into eight 100 Gb/s planes, enabling full‑mesh connectivity for over 100 k GPUs with fewer switches, lower cost, higher resilience, and dynamic load‑balancing that eliminates congestion and hardware‑failure impacts during large‑scale AI training.
