## Summary
At the OCP Summit 2026, Meta announced several AI-scale networking innovations, including the IcePack liquid-cooled rack and IceCube 102.4T switch blades. The company is also launching the Open Switch Platform Architecture (OSPA) initiative alongside Microsoft and Alibaba to standardize the switch platform layer. Additionally, Meta shared details on its Flattened Planar Fabric (FPF) and open-source implementations of its MetaRoCE transport protocol.

## Technical breakdown of Meta's AI networking
- **IceCube switches**: 102.4 Tbps capacity providing 128×800G non-blocking switching; available with Broadcom Tomahawk6C or NVIDIA Spectrum-6 ASICs.
- **IcePack rack**: A liquid-cooled network rack based on the OCP ORV3-HPRv1 standard.
- **Flattened Planar Fabric (FPF)**: A 2-tier Clos fabric where each GPU connects via eight independent 100G links to eight different switches.
- **OSPA**: A new OCP initiative co-led by Meta, Microsoft, and Alibaba to standardize switch platform specifications (v1.0 submitted).
- **MetaRoCE**: Open-source implementations of Meta's RDMA transport protocol for AI networks.

## Why it matters
The OSPA initiative aims to standardize the switch platform layer across vendors, while the open-source MetaRoCE and FBOSS implementations provide reusable networking software for the AI industry.
