SP+WRR queuing
To implement SP+WRR queuing, assign some queues to the SP scheduling group, some to WRR
scheduling group 1, and the others to WRR scheduling group 2. During queue scheduling, queues in
each WRR scheduling group are scheduled by using WRR according to their weights, and then the
dequeued packets together with the packets in the SP scheduling group are scheduled by using SP
queuing.
For example, suppose you assign queues 0 and 1 to WRR scheduling group 1, with their weights 1 and
2, assign queue 3 to WRR scheduling group 2, with its weight 1, and assign queue 2 to the SP scheduling
group. The scheduling process is as shown in Figure 13 .

Configuring SP queuing
SP queuing comprises basic SP queuing and multi-mode SP queuing. Support for SP queuing modes
depends on your device model.
