Method
Select
SPQ
(Strictly Priority Queuing),
WFQ
(Weighted Fair Queuing) or
WRR
(Weighted Round Robin).
Strictly Priority Queuing services queues based on priority only. When the highest priority queue
empties, traffic on the next highest-priority queue begins. Q7 has the highest priority and Q0 the
lowest.
Weighted Fair Queuing is used to guarantee each queue's minimum bandwidth based on their
bandwidth portion (weight) (the number you configure in the
Weight
field). Queues with larger
weights get more guaranteed bandwidth than queues with smaller weights.
Weighted Round Robin Scheduling services queues on a rotating basis based on their queue weight
(the number you configure in the queue
Weight
field). Queues with larger weights get more service
than queues with smaller weights.
Weight
When you select
WFQ
or
WRR
, enter the queue weight here. Bandwidth is divided across the different
traffic queues according to their weights.
