# The Network Defines the AI Data Center

Next-generation networking for high-performance, scalable, and secure gigascale AI factories.

Introduction

## Networking Purpose-Built for the Era of AI Factories

[AI factories](https://www.nvidia.com/en-us/glossary/ai-factory.md) now span tens of thousands of GPUs—and soon, millions—operating as a single distributed computing engine. To keep accelerators fully utilized, AI workloads demand deterministic latency, lossless throughput, stable iteration times, and the ability to scale not only within a data center, but across multiple sites.

NVIDIA networking delivers the full-stack fabric that makes this possible, combining [NVIDIA NVLink™](https://www.nvidia.com/en-us/data-center/nvlink.md) scale-up, [NVIDIA Quantum InfiniBand](https://www.nvidia.com/en-us/networking/infiniband-switching.md) and [Spectrum-X™ Ethernet](https://www.nvidia.com/en-us/networking/spectrumx.md) scale-out, Spectrum-XGS multi-data-center scale-across, [NVIDIA® BlueField® DPU](https://www.nvidia.com/en-us/networking/products/data-processing-unit.md) and [DOCA™](https://developer.nvidia.com/networking/doca) for infrastructure services, and next-generation [silicon-photonics platforms](https://www.nvidia.com/en-us/networking/products/silicon-photonics.md) to power the world’s most advanced AI factories.
