Robotron: Top-down network management at scale

What this post added

This post introduces Robotron, a top-down network management system designed to manage Facebook's massive production network of tens of thousands of devices and hundreds of thousands of servers. It details the system's evolution from initial monitoring efforts (FBNet) to a comprehensive solution covering network design, configuration generation, deployment, and monitoring. Key challenges addressed include distributed configurations, handling multiple domains, versioning, dependencies, and vendor differences. The system translates high-level operator intent into vendor-specific configurations and deploys/monitors them to ensure network state consistency. The post also highlights the open-sourcing of parts of Robotron, such as fbpush.
