Weighted Fair Queue and Fair Queue (WFQ/FQ)
Figure 27 depicts the mixed Weighted Fair Queue (WFQ) scheduling model for HQoS customer
traffic. All the 4 scheduler inputs are WFQ. If all the 4 scheduler inputs are equal, the scheduling
model is FQ.
FIGURE 27 Weighted Fair Queue and Fair Queue
The supportable weight range for each input is <1-64>.
HQoS-QT stands for hqos-queue-type. The range is <8-11>.
IP stands for internal priority. The range is <0-7>.
PR stands for scheduler-input (the ordering of a flow with respect to a scheduler which is specified
in the hqos scheduler policy). The range is <0-3>.
