Which QoS feature drops traffic that exceeds the committed access rate?

Policing is a QoS mechanism that meters traffic and enforces a configured rate limit by dropping packets that exceed the committed access rate, ensuring that the traffic flow adheres to the specified bandwidth constraints. It typically results in immediate dropping of non-compliant traffic.

FIFO (First-In, First-Out) is a basic queuing method that processes packets in the order they arrive, without any rate limiting or dropping based on exceeding a committed rate.

Shaping (traffic shaping) buffers excess traffic that exceeds the committed rate and sends it out later, smoothing the output rate, rather than dropping it immediately.

Weighted Fair Queuing (WFQ) is a scheduling algorithm that provides fair bandwidth allocation among different traffic flows based on weights, but it does not primarily drop traffic for exceeding a committed rate.
