Config Paths

ns3::EdcaTxopN is accessible through the following paths with Config::Set and Config::Connect:

• /NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Mac/$ns3::RegularWifiMac/BE_EdcaTxopN
• /NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Mac/$ns3::RegularWifiMac/BK_EdcaTxopN

• /NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Mac/$ns3::RegularWifiMac/VO_EdcaTxopN

Attributes

• BlockAckThreshold: If number of packets in this queue reaches this value, block ack mechanism is used. If this value is 0, block ack is never used.
  • Set with class: ns3::UintegerValue
  • Underlying type: uint8_t 0:64
  • Initial value: 0
  • Flags: construct write read
• BlockAckInactivityTimeout: Represents max time (blocks of 1024 micro seconds) allowed for block ack inactivity. If this value isn't equal to 0 a timer start after that a block ack setup is completed and will be reset every time that a block ack frame is received. If this value is 0, block ack inactivity timeout won't be used.

void ns3::EdcaTxopN::DoDispose ( void  )

virtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden 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.

Reimplemented from ns3::Object.

void ns3::EdcaTxopN::DoInitialize ( void  )

privatevirtual

This method is called only once by Object::Initialize.

If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.
