Low-latency queuing is the QoS prioritization mechanism designed for real-time interactive traffic such as voice and video because it provides a strict priority queue, minimizing delay and jitter. Traffic policing controls rate rather than priority, round-robin scheduling does not give real-time traffic strict precedence, and expedited forwarding is a forwarding behavior/class designation rather than the queuing method itself.
