NVIDIA Spectrum-X — the Open, AI-Native Ethernet Fabric — Sets the Standard for Gigascale AI, Now With MRC

The race to build the world’s most powerful AI factories demands networking that keeps pace with the ambitions of AI itself.

NVIDIA Spectrum-X Ethernet scale-out infrastructure stands at the forefront of that race as the most advanced AI networking technology available today, deployed by industry leaders who can’t afford to compromise on performance, resilience or scale.

That includes OpenAI, Microsoft and Oracle.

Companies including NVIDIA, Microsoft and OpenAI have demonstrated industry leadership by introducing Multipath Reliable Connection (MRC), an RDMA transport protocol. MRC enables a single RDMA connection to distribute traffic across multiple network paths, improving throughput, load balancing and availability for large-scale AI training fabrics.

Think of it as replacing a single-lane road spanning a town with a cleverly laid-out street grid system paired with an on-the-fly traffic app, enabling drivers to reroute around slowdowns and road closures.
