Detailed Description

FrameExchangeManager is a base class handling the basic frame exchange sequences for non-QoS stations.

The fragmentation policy implemented uses a simple fragmentation threshold: any packet bigger than this threshold is fragmented in fragments whose size is smaller than the threshold.

The retransmission policy is also very simple: every packet is retransmitted until it is either successfully transmitted or it has been retransmitted up until the SSRC or SLRC thresholds.

DoDispose()

void ns3::FrameExchangeManager::DoDispose ( )

overrideprotectedvirtual

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.
