Detailed Description

Abstract interface for classes that encapsulate the functionality of reassembling frames from fragments.

Fragmentation reassembly classes are typically instantiated as part of an UpperMac.

Constructor & Destructor Documentation

◆ ~IReassembly()

virtual inet::ieee80211::IReassembly::~IReassembly ( )

inlinevirtual

26 {}

Member Function Documentation

◆ addFragment()

virtual Packet* inet::ieee80211::IReassembly::addFragment ( Packet * frame )

pure virtual

Add a fragment to the reassembly buffer.

If the new fragment completes a frame, then the reassembled frame is returned (and fragments are removed from the buffer), otherwise the function returns nullptr.

Implemented in inet::ieee80211::BasicReassembly.

Referenced by inet::ieee80211::RecipientMacDataService::defragment(), and inet::ieee80211::RecipientQosMacDataService::defragment().

◆ purge()

virtual void inet::ieee80211::IReassembly::purge	(	const MacAddress &	address,
		int	tid,
		int	startSeqNumber,
		int	endSeqNumber
	)

pure virtual

Discard fragments from the reassembly buffer.

Frames are identified by the transmitter address, the TID, and the sequence number range [startSeqNumber, endSeqNumber[. Set tid=-1 for non-QoS frames.
