This post details Meta's '10X Backbone' initiative to scale its Backbone network for AI workloads. It introduces DC Metro Architecture for simplified and standardized DC connectivity, IP Platform Scaling (scaling up with larger chassis and faster interfaces like 800G, and scaling out by adding planes or devices), and IP/Optical Integration using ZR technology to significantly reduce power consumption and simplify deployments. For AI cluster expansion beyond data center campuses, solutions for different reach requirements (FR, LR, and ZR plugs with DWDM) are presented.
