Scheduling Overview
Scheduling determines the priority among the queues. IP-20 provides a
unique hierarchical scheduling model that includes four priorities, with
Weighted Fair Queuing (WFQ) within each priority, and shaping per port and
per queue.
The scheduler scans the queues and determines which queue is ready to
transmit. If more than one queue is ready to transmit, the scheduler
determines which queue transmits first based on:
Queue Priority – A queue with higher priority is served before
lower-priority queues.
Weighted Fair Queuing (WFQ) – If two or more queues have the same
priority and are ready to transmit, the scheduler transmits frames from
the queues based on a WFQ algorithm that determines the ratio of frames
per queue based on a predefined weight assigned to each queue.
