Weighted Round Robin Priority Scheduling
The weighted round robin (WRR) scheduling method functions as its
name implies. The port transmits a set number of packets from each
queue, in a round robin fashion, so that each has a chance to transmit
traffic.Normally, the higher the queue’s priority the more packets are
transmitted in as the algorithm cycles through the queues in turn. This
method guarantees that every queue receives some attention from the
port for transmitting packets.
Table 5 shows the WRR settings for the number of packets transmitted
from each queue. These values are permanent and you cannot be change
these values.
