Is strict priority queuing preferred for real-time services?

Strict priority queuing is indeed preferred for real-time services because it ensures that high-priority traffic, such as audio or video streams, is transmitted ahead of lower-priority traffic. This method minimizes delays and jitters, which are detrimental to the quality of real-time applications. Real-time services require timely delivery of data packets to maintain the integrity of audio or video playback, making strict priority queuing an effective approach.

By assigning higher priority to real-time data, such as that used in DANTE for audio over IP, strict priority queuing helps guarantee that these critical data packets are processed first, ahead of less critical traffic. Therefore, this queuing strategy supports the necessary network performance levels for applications that demand immediate and consistent data delivery.
