4.8.1.3 Queue Scheduling
The switch support eight CoS queues for each egress port. For each of the eight
queues, two types of scheduling can be configured: Strict Priority and Weighted
Round Robin (WRR).
Strict Priority scheduling is based on the priority of queues. Packets in a high-priority
queue are always sent first and packets in a low-priority queue are only sent after all
the high priority queues are empty.
Weighted RoundRobin (WRR) scheduling is based on the user priority specification
to indicate the importance (weight) of the queue relative to the other CoS queues.
WRR scheduling prevents low-priority queues from being completely ignored during
periods of high priority traffic. The WRR scheduler sends some packets from each
queue in turn.
