Practical Intent-driven Routing Configuration Synthesis
summary
Aura is a production routing-synthesis system that precomputes and preloads multiple base paths and switches among them via staging and labeling, using BGP community tags (pathcom, stockcom, paulcon) to activate policy fragments. It introduces the RPL language for conditional, device-state policies and simplifies topology to generate reusable path graphs. Deployed across five datacenters (Sep 2021–Sep 2022), it produces 54 configuration versions covering ~800,000 policy variants, halves review time and cuts reviewer/operator revision count by ~3x.
