5-2 Configuring QoS
v1.0, March 2008
• Weighted Round Robin – Ensures that a single application does not dominate the device
forwarding capacity. Weighted Round Robin (WRR) forwards entire queues in a round robin
order. All queues can participate in WRR, except SP queues. If the traffic flow is minimal, and
SP queues do not occupy the whole bandwidth allocated to a port, the WRR queues can share
the bandwidth with the SP queues. This ensures that the remaining bandwidth is distributed
according to the weight ratio. If WRR is selected, the following weights are assigned to the
queues: 1, 2, 4, 8.
