Method Detail

setupBehaviour

protected boolean setupBehaviour(String opName)

Description copied from class: AbstractP4RuntimeHandlerBehaviour

Initializes this behaviour attributes. Returns true if the operation was successful, false otherwise.

Overrides:

setupBehaviour in class AbstractP4RuntimeHandlerBehaviour

Parameters:

opName - name of the operation

Returns:

true if successful, false otherwise

performMeterOperation

public CompletableFuture<Boolean> performMeterOperation(org.onosproject.net.meter.MeterOperation meterOp)

Specified by:

performMeterOperation in interface org.onosproject.net.meter.MeterProgrammable

getMeters

public CompletableFuture<Collection<org.onosproject.net.meter.Meter>> getMeters()

Specified by:

getMeters in interface org.onosproject.net.meter.MeterProgrammable

getMeterFeatures

public CompletableFuture<Collection<org.onosproject.net.meter.MeterFeatures>> getMeterFeatures()

Specified by:

getMeterFeatures in interface org.onosproject.net.meter.MeterProgrammable

isSimilar

protected boolean isSimilar(org.onosproject.net.pi.runtime.PiMeterCellConfig onosMeter,
                            org.onosproject.net.pi.runtime.PiMeterCellConfig deviceMeter)

Returns true if the given PiMeterCellConfigs are similar enough to be deemed equal for reconciliation purposes. This is required to handle read/write asymmetry in devices that allow variations in the meter rate/burst. E.g., devices that implement metering with a rate or burst size that is slightly higher/lower than the configured ones, so the values written by ONOS will be different than those read from the device.

Parameters:

onosMeter - the ONOS meter

deviceMeter - the meter in the device

Returns:

true if the meters are similar, false otherwise
