Chapter 18 Queuing Method
Weighted Round Robin Scheduling (WRR) uses the same algorithm as round robin scheduling, but services queues based on their priority and queue weight (the number you configure in the queue Weight field) rather than a fixed amount of bandwidth. WRR is activated only when a port has more traffic than it can handle. Queues with larger weights get more service than queues with smaller weights. This queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues and returns to queues that have not yet emptied.

LABEL | DESCRIPTION |
Method | Select Strictly Priority or Weighted Round Robin Scheduling. |
| Strict Priority Queuing (SPQ) services queues based on priority only. When the highest |
| priority queue empties, traffic on the next |
| highest priority and Q0 the lowest. The default queuing method is Strictly Priority. |
| Weighted Round Robin Scheduling (WRR) 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. |
| When you select Strict Priority, it applies to Q3 only (with priority over all other queues). |
| Q0 ~ Q2 will use Weighted Round Robin Scheduling. |
