The bandwidth assigned to a queue = the minimum guaranteed bandwidth + the bandwidth
allocated to the queue from the assignable bandwidth.
SP+WRR queuing
You can assign some queues on a port to the SP scheduling group and the others to the WRR scheduling
group (group 1) to implement SP + WRR queue scheduling. The switch schedules packets in the SP
scheduling group preferentially, and when the SP scheduling group is empty, schedules the packets in the
WRR scheduling group. Queues in the SP scheduling group are scheduled with the SP queue scheduling
algorithm. Queues in the WRR scheduling group are scheduled with WRR.
SP+WFQ queuing
SP+WFQ queuing is similar to SP+WRR queuing. You can assign some queues on a port to the SP
scheduling group and the others to the WFQ scheduling group to implement SP + WFQ queue
scheduling. The switch schedules packets of queues in the WFQ group based on their minimum
guaranteed bandwidth settings, then uses SP queuing to schedule the queues in the SP scheduling group,
and at last uses WFQ to schedule the queues in the WFQ scheduling group in a round robin fashion
according to their weights
