In their unrelenting quest for lower latency, cloud providers are deploying servers closer to their customers and enterprises are adopting paid Network-as-a-Service (NaaS) offerings with performance guarantees. Unfortunately, these trends contribute to greater industry consolidation, benefiting larger companies and well-served regions while leaving little room for smaller cloud providers and enterprises to flourish.

More concretely, we envision an incrementally deployable system, namely Tango, that allows individual pairs of edge networks (e.g., access, enterprise, and data-center networks) to optimize Internet paths between them without collaboration from the Internet core.
