Systems support PQ, WRR, WRR + PQ scheduling model. When a queue is empty,system can
switch immediately to the next queue scheduling,it make full use of bandwidth resource.
o
When existing WRR queue scheduling, the sum of weights must be 100
o The
WRR + PQ scheduling mode is a mixture of WRR and PQ two scheduling model.
When there is a zero value in the weight of the queue, queue scheduling model is the
PQ + WRR scheduling model. In this mode, the system schedule queue that weight is
0in PQ model, then scheduling queue that weights isn’t 0 in the WRR mode, and the
priority of PQ queue is higher than the WRR queue.
o
When Configure WRR + PQ way queue scheduling, the queue of PQ mode
scheduling must be configured in the priority queue, do not allow the PQ queue
alternating configure.with WRR queue
o
The default scheduling of system is PQ scheduling
【Example】
Example: configure the queue scheduling model is WRR, making all kinds of priority message
can be scheduled. The weight of the queue 0-3 is 10,30,30,30 respectively
