◆ NotifySwitchingStartNow()

template<typename TxopType >
void FrameExchangeManagerStub< TxopType >::NotifySwitchingStartNow ( Time duration)
inlineoverridevirtual

Parameters
durationswitching delay duration.

This method is typically invoked by the PhyListener to notify the MAC layer that a channel switching occurred. When a channel switching occurs, pending MAC transmissions (RTS, CTS, Data and Ack) are cancelled.

MHz_u allowedWidth )
inlineoverridevirtual

Request the FrameExchangeManager to start a frame exchange sequence.

Parameters
