Example
To adopt the WRR scheduling mode and set the weight values of the eight queues to 10, 10, 20,
20, 10, 10, 10, and 10 respectively, do as follows:
Issue 04 (2011-10-30)
The system supports WRR for eight queues. Each queue has a weight value (w7, w6, w5,
w4, w3, w2, w1, and w0 in a descending order) for resource acquisition. In the WRR
scheduling mode, the queues are scheduled in turn, which ensures that each queue can be
scheduled.
Table 3-20 lists the mapping between the queue weights and the actual queues.

1 W1
0 W0
Wn: Indicates the weight of queue n. The weight sum of the queues (except the queue with
weight value 255) must be equal to 0 or 100, where 0 indicates that the strict PQ scheduling
mode is used and 255 indicates that the queue is not used.
PQ+WRR
– The system schedules some queues by PQ and schedules the other queues by WRR.
When the specified WRR value is 0, it indicates that the queue is scheduled in the PQ
mode.
– The queue scheduled in the PQ mode should be the queue that has the highest priority.
– The weight sum of the scheduled queues must be equal to 100.
