Priority Transmission Queues for High-Priority Network Traffic

The transmission queue is segmented into multiple priority levels (e.g., high priority and low priority queues). The scheduler processes high priority traffic separately from low priority traffic, ensuring that high priority frames are transmitted before low priority frames, thus eliminating the delay caused by round robin scheduling while maintaining fairness within each priority level.

Different quality of service is applied to different priority levels. High priority traffic receives preferential treatment with dedicated transmission opportunities, while low priority traffic follows standard FIFO processing. This local differentiation maintains simplicity within each queue while achieving effective priority-based transmission reliability across the system.

The high priority transmission functionality is extracted as a separate, dedicated queue that operates independently from the standard FIFO queue. This extraction allows high priority traffic to be handled with minimal complexity overhead, as it simply requires checking the high priority queue first before processing the standard queue, rather than implementing complex priority arbitration within a single queue.

The scheduling system is made dynamic by allowing the selection between different scheduling modes (standard FIFO/round robin and priority-based scheduling). This dynamic capability enables the network to adapt to different application requirements, maintaining compatibility with existing standards when priority scheduling is not needed, while providing enhanced productivity for latency-sensitive applications when priority scheduling is activated.
