Detailed Description

This class is an ns-3 trace sink that performs the calculation of PDU statistics for uplink and downlink.

Statistics are generated on a per radio bearer basis. This class can be used for RLC PDU stats or PDCP PDU stats by connecting to the appropriate trace sources at the RLC or PDCP layer.

The statistics are calculated at consecutive time windows and periodically written to a file. The calculated statistics are:

Number of transmitted PDUs
Number of received PDUs
Number of transmitted bytes
Number of received bytes
Average, min, max and standard deviation of PDU delay (delay is calculated from the generation of the PDU to its reception)
Average, min, max and standard deviation of PDU size

Here is the call graph for this function:

◆ DoDispose()

void ns3::RadioBearerStatsCalculator::DoDispose ( void )

overridevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

Here is the call graph for this function:

◆ EndEpoch()

void ns3::RadioBearerStatsCalculator::EndEpoch ( )

Function called in every endEpochEvent.
