TANGO: Secure Collaborative Route Control across the Public Internet

Explore a groundbreaking conference talk from NSDI '24 that introduces TANGO, a novel approach to secure collaborative route control across the public Internet. Discover how TANGO enables smaller edge networks to expose paths and exert route control without relying on third parties or cooperation from the Internet core. Learn about the innovative techniques used by TANGO edges to jointly expose more BGP-compliant wide-area paths, collect fine-grained telemetry, and dynamically reroute traffic in the data plane. Delve into the Internet-scale experiments that reveal rich path diversity and significant performance improvements, including latency reductions of up to 39% compared to default BGP paths. Gain insights into how TANGO addresses the challenges faced by smaller edge networks in meeting the demands of modern latency-critical applications without the need for costly private WANs or Network-as-a-Service solutions.
