Where:
UsedRate = Applicable uplink/downlink MIR or CIR
PIF = Proportional IR Factor
AvgRate = Average Rate
ConfiguredRate = Configured uplink/downlink MIR or CIR
ThrRate = Proportional IR Threshold Rate
The formula for the average rate is:
Where
F
i
= Number of frames sent on modulation i
R
i
= Data rate in Mbps for modulation i
Examples:
The following parameters are available for configuration:
