FBOSS (Meta network operating system)

FBOSS is Meta's open-source network operating system, originally introduced in 2018 (research-in-brief blog post) and positioned as the software layer controlling Meta's network switches. FBOSS, together with OCP-SAI, is the control-plane substrate for Meta's Disaggregated Scheduled Fabric (DSF).

Seen in

• sources/2024-10-15-meta-metas-open-ai-hardware-vision — "DSF is powered by the open OCP-SAI standard and FBOSS, Meta's own network operating system for controlling network switches." FBOSS is the NOS layer underneath DSF.

Why it matters

• Disaggregation enabler. FBOSS + OCP-SAI together decouple network control-plane from vendor-specific switch firmware, which is a precondition for the vendor-agnostic DSF fabric.
• Long-run Meta investment. FBOSS has been in production at Meta since 2018; the 2024-10 DSF announcement extends its role from pre-AI-scale data-center fabrics into AI-scale training backends.
