Nvidia-backed Upscale takes on AI networking silos with Token Fabric

AI clusters depend on two types of networking.

The short version

• Scale-up networking connects accelerators inside a rack.
• Scale-out networking connects racks across the data center.
• A single AI job spans both, which is a challenge for many organizations that tend to treat the two as separate networks.

What happened

Networking startup Upscale today introduced Token Fabric to bring the two together. The architecture combines the company’s own SkyFabriX scale-up silicon, scale-out systems built on Nvidia Spectrum-X Ethernet, and a common software layer for operations.

Why it matters

General availability is planned for early 2027.
