Open/R: Open routing for modern networks

This post announces the open-sourcing of Open/R, an extensible network routing platform designed for rapid innovation in network functions and applications. Open/R is being used in Facebook's backbone, data center, and wireless mesh networks, supporting various topologies and hardware. It provides a platform for disseminating network state and building new applications, with northbound interfaces for external controllers. Key features include automatic IP prefix allocation, RTT-based cost metrics, graceful restart, and fast convergence. The post highlights external adoption by partners like WiLine Networks and encourages broader community engagement.
