Explanation

The data plane (also called the forwarding plane) is responsible for the actual forwarding of packets, and it enforces QoS policies during that forwarding process. This includes queuing, scheduling, traffic shaping, and marking of packets in real time as they pass through the device. The control plane determines routing and builds forwarding tables. The management plane handles device configuration and monitoring (e.g., SSH, SNMP). QoS enforcement happens at packet-forwarding time, making it a data plane function.
