◆ DoDispose()

void ns3::WifiNetDevice::DoDispose ( )
overrideprotectedvirtual

Destructor implementation.

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

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

◆ DoInitialize()

void ns3::WifiNetDevice::DoInitialize ( )

Initialize() implementation.

◆ GetAddress()

Address ns3::WifiNetDevice::GetAddress ( ) const
overridevirtual
Returns
the current Address of this interface.

Normally, the MAC address that the network device has to advertise to upper layers is the MLD address, if this device is an MLD, or the unique MAC address, otherwise. Advertising the MAC address returned by WifiMac::GetAddress() is therefore the right thing to do in both cases. However, there is an exception: if this device is a non-AP MLD associated with a single link AP (hence, no ML setup was done), we need to advertise the MAC address of the link used to communicate with the AP. In fact, if we advertised the MLD address, the AP could not forward a frame to us because it would not recognize our MLD address as the MAC address of an associated station.

◆ GetMulticast() [1/2]

Address ns3::WifiNetDevice::GetMulticast ( Ipv4Address  multicastGroup) const
overridevirtual

Make and return a MAC multicast address using the provided multicast group.

RFC 1112 says that an Ipv4 host group address is mapped to an Ethernet multicast address by placing the low-order 23-bits of the IP address into the low-order 23 bits of the Ethernet multicast address 01-00-5E-00-00-00 (hex). Similar RFCs exist for Ipv6 and Eui64 mappings. This method performs the multicast address creation function appropriate to the underlying MAC address of the device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact MAC address format.

In the case of net devices that do not support multicast, clients are expected to test NetDevice::IsMulticast and avoid attempting to map multicast packets. Subclasses of NetDevice that do support multicasting are expected to override this method and provide an implementation appropriate to the particular device.

Parameters
multicastGroupThe IP address for the multicast group destination of the packet.
Returns
The MAC multicast Address used to send packets to the provided multicast group.
Warning
Calling this method is invalid if IsMulticast returns not true.
