QoS Overview
The value specified for the TAF affects the speed at which the shared buffer average utilization
tracks the instantaneous shared buffer utilization. A low value weights the new shared buffer
average utilization calculation more to the shared buffer instantaneous utilization. When TAF is
zero, the shared buffer average utilization is equal to the instantaneous shared buffer utilization. A
high value weights the new shared buffer average utilization calculation more to the previous
shared buffer average utilization value. The TAF value applies to all high and low priority RED
slopes for ingress and egress buffer pools controlled by the buffer policy.
