Explanation:
Low Latency Queueing feature brings the ability to specify low latency behavior for a traffic class for both VIP and non-VIP platforms. Low Latency Queuing allows
delay-sensitive data such as voice to be dequeued and sent first (before packets in other queues are dequeued), giving delay-sensitive data preferential treatment
over other traffic. Low Latency Queuing also introduces transmission ring limit tuning.
