Functions

uint8_t ns3::GetTid (Ptr< const Packet > packet, const WifiMacHeader hdr)
 This function is useful to get traffic id of different packet types. More...
 
bool ns3::operator< (enum AcIndex left, enum AcIndex right)
 Operator< overload returning true if the AC on the left has lower priority than the AC on the right. More...
 
bool ns3::operator<= (enum AcIndex left, enum AcIndex right)
 Operator<= overload returning true if the AC on the left has lower or the same priority than the AC on the right. More...
 
bool ns3::operator> (enum AcIndex left, enum AcIndex right)
 Operator> overload returning true if the AC on the left has higher priority than the AC on the right. More...
 
bool ns3::operator>= (enum AcIndex left, enum AcIndex right)
 Operator>= overload returning true if the AC on the left has higher or the same priority than the AC on the right. More...
 
uint8_t ns3::QosUtilsGetTidForPacket (Ptr< const Packet > packet)
 If a QoS tag is attached to the packet, returns a value < 8. More...
 
bool ns3::QosUtilsIsOldPacket (uint16_t startingSeq, uint16_t seqNumber)
 This function checks if packet with sequence number seqNumber is an "old" packet. More...
 
uint32_t ns3::QosUtilsMapSeqControlToUniqueInteger (uint16_t seqControl, uint16_t endSequence)
 Next function is useful to correctly sort buffered packets under block ack. More...
 
AcIndex ns3::QosUtilsMapTidToAc (uint8_t tid)
 Maps TID (Traffic ID) to Access classes. More...
 
uint8_t ns3::SelectQueueByDSField (Ptr< QueueItem > item)
 Determine the TX queue for a given packet. More...
 

Variables

const std::map< AcIndex, WifiAc > ns3::wifiAcList
 Map containing the four ACs in increasing order of priority (according to Table 10-1 "UP-to-AC Mappings" of 802.11-2016) More...
