LABEL DESCRIPTION
SPQ Select SPQ (Strict Priority Queuing) to service queues based on priority only. When the
highest priority queue empties, traffic on the next highest-priority queue begins. The default
queuing method is Strictly Priority.
Weighted Fair Scheduling 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.
WRR Select WRR (Weighted Round Robin Scheduling) to service queues on a rotating basis
based on their queue weight (the number you select from the drop-down list box for the
corresponding queue). Queues with larger weights get more service than queues with
smaller weights.
