"The programmable fabric can be broken down into two main layers, the control plane and the data plane.
Control Plane Layer
The control plane layer is responsible for configuring and managing the data plane and is normally more centrally located, i.e., one per PoP or region.
The control plane is normally divided into three separate domains - Fabric, Telemetry & Configuration and Management - to allow them to scale independently. However, they could be implemented in one software controller, for example in a small-scale implementation..."
