◆ QosUtilsGetTidForPacket()

If a QoS tag is attached to the packet, returns a value < 8.

A value >= 8 is returned otherwise.

◆ QosUtilsIsOldPacket()

bool ns3::QosUtilsIsOldPacket	(	uint16_t	startingSeq,
		uint16_t	seqNumber
	)

This function checks if packet with sequence number seqNumber is an "old" packet.

The sequence number space is considered divided into two parts, one of which is "old" and one of which is "new" by means of a boundary created by adding half the sequence number range to the starting sequence number startingSeq. So this function works fine also when seqNumber is smaller than startingSeq and startingSeq + 2048 is greater than 4096 because all comparison are circular modulo 2^12. The following are possible scenarios:

--— = old packets +++++ = new packets

CASE A:

0 4095 |++++++|-------------—|++++++| ^ ^ | endSeq | startingSeq

CASE B:

0 4095 |---—|++++++++++++++++|--—| ^ ^ | startingSeq | endSeq

Here in the examples endSeq is the sequenceNumber of the "last" new packet. So this function, when specified a starting sequence and a sequence number, returns true if that packet (with sequence number numberSeq)) belongs to the section of the sequence number space marked with '-' characters. The function returns false otherwise.

Parameters

startingSeq	the starting sequence number
seqNumber	the sequence number to be checked

Returns: true if the packet is old, false otherwise

◆ QosUtilsMapSeqControlToUniqueInteger()

uint32_t ns3::QosUtilsMapSeqControlToUniqueInteger	(	uint16_t	seqControl,
		uint16_t	endSequence
	)

Next function is useful to correctly sort buffered packets under block ack.

When an BAR is received from originator station, completed "old" (see section 9.10.3 in IEEE 802.11e) packets must be forwarded up before "new" packets.

Parameters

seqControl	the sequence control field
endSequence	the sequence number ending the acknowledgment window

Returns: a unique integer for the given sequence control and end sequence

Here is the caller graph for this function:

◆ SelectQueueByDSField()

uint8_t ns3::SelectQueueByDSField ( Ptr< QueueItem > item )

Determine the TX queue for a given packet.

Parameters

item	the packet

Returns: the access category

Modeled after the Linux function ieee80211_select_queue (net/mac80211/wme.c). A SocketPriority tag is attached to the packet (or the existing one is replaced) to carry the user priority, which is set to the three most significant bits of the DS field (TOS field in case of IPv4 and Traffic Class field in case of IPv6). The Access Category corresponding to the user priority according to the QosUtilsMapTidToAc function is returned.
