Class CIM_EWMAMeterService
extends CIM_MeterService

This class represents a logical entity that resides in the data forwarding path of a network device. It describes the metering of network traffic using an Exponentially Weighted Moving Average meter. This meter can be modeled as a simple IIR low-pass filter that measures the rate of incoming packets over a small fixed sampling interval. Any admitted packet that pushes the average rate over a pre-defined limit is defined to be non-conforming. This is modeled as a subclass of ConditioningService and has the ability to invoke different ConditioningServices for conforming and non-conforming traffic.

AverageRatereal32
DescriptionstringThis property is a 32-bit real number that defines the average rate against which the sampled arrival rate of packets should be measured. Any packet that causes the sampled rate to exceed this rate is deemed non-conforming.None TRANSLATABLE= true
UnitsstringKiloBits Per SecondNone TRANSLATABLE= true
DeltaIntervaluint64
DescriptionstringThis property is a 64-bit unsigned integer that defines the sampling interval used to measure the arrival rate in bytes. The calculated rate is averaged over this interval and checked against the AverageRate property. All packets whose computed average arrival rate is less than the AverageRate are deemed conforming.None TRANSLATABLE= true
UnitsstringNanoSecondsNone TRANSLATABLE= true
Gainreal32
DescriptionstringThis property is a 32-bit real number that defines the time constant (e.g. frequency response) of what is essentially a simple IIR low-pass filter.None TRANSLATABLE= true
