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.
50.2 Configuring Queuing
Use this screen to set priorities for the queues of the Switch. This distributes bandwidth across the different
traffic queues.
