23.1.3 Weighted Round Robin Scheduling (WRR)
Round Robin Scheduling services queues on a rotating basis and is activated only when a port has
more traffic than it can handle. A queue is a given an amount of bandwidth irrespective of the
incoming traffic on that port. This queue then moves to the back of the list. The next queue is given
an equal amount of bandwidth, and then moves to the end of the list; and so on, depending on the
number of queues being used. This works in a looping fashion until a queue is empty.
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.
