Panorama: Optimizing Internet-scale Users’ Routes from End to End
summary
Panorama is a globally deployed hybrid overlay that runs a centralized controller and distributed route servers to compute end-to-end routes using measurement-based user grouping, K-shortest-path reuse and a simplified multicommodity flow solver. Deployed since 2021 over 30+ SEs across 66 countries, evaluation uses 81 million selected real-world traces and shows latency <200ms for 96.34% of sessions and SLA satisfaction improvement up to 88.0%, demonstrating large-scale effectiveness.
