Detailed Description

Calculation of statistics from the RLC layer for uplink and downlink, the data is dumped into a file periodically. Metrics considered are:

Number of transmitted PDUs
Number of received PDUs
Number of transmitted bytes
Number of received bytes
Average, min, max and standard deviation of RLC to RLC delay
Average, min, max and standard deviation of RLC PDU size TODO: Actual statistics calculation implies checking the time every time a packet is send or received so it is not very efficient. The epoch implementation should be replaced by a timer to avoid this overhead.

This type is not accessible from the Config system.

void ns3::RadioBearerStatsCalculator::DoDispose ( void )

virtual

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

Subclasses are expected to implement their real destruction code in an overriden 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.
