In software-defined networking, which component is responsible for providing the actual physical pathways that data packets traverse across network devices?
Control plane
Underlay network
Overlay network
Orchestration layer
The underlay network is the physical infrastructure consisting of the actual routers, switches, and links that carry data packets. It provides the physical pathways for data transmission. The overlay network, on the other hand, is a virtual network built on top of the underlay network, enabling network virtualization and abstraction. The control plane manages network policies and decisions but does not provide physical pathways. The orchestration layer handles the coordination of network resources, not the physical data transmission.
