Argo and the Cloudflare Global Private Backbone

Argo is dependent on a few things to make its magic happen: Cloudflare’s network, up-to-the-second performance data on how traffic is moving on the Internet, and machine learning routing algorithms. A single Cloudflare data center may be peered with a dozen networks, connected to multiple Internet eXchanges (IXs), connected to multiple transit providers (e.g. Telia, GTT, etc), and now, connected to our own physical backbone. Transit selection requires logic in our inter-data center data plane (the components that actually move data across our network) to allow for differentiation between different providers and links available in each location.
