Decentralized and diverse, the Internet is resilient and universal. However, its distributed nature leads to operational brittleness and difficulty in identifying and tracking the root causes of performance and availability issues.

To address this, we advocate a measurement plane, or mPlane alongside the Internet’s data and control planes.
