Detailed Description

Network layer to device interface.

The ns3::NetDevice includes IP-specific API such as GetMulticast(), Send() and SendTo() methods, which do not map well the the 802.15.4 MAC MCPS DataRequest primitive. So, the basic design is to provide, as much as makes sense, the class ns3::NetDevice API, but rely on the user accessing the LrWpanMac pointer to make 802.15.4-specific API calls. As such, this is really just an encapsulating class.

◆ BuildPseudoMacAddress()

Mac48Address ns3::lrwpan::LrWpanNetDevice::BuildPseudoMacAddress	(	uint16_t	panId,
		Mac16Address	shortAddr ) const

private

Builds a "pseudo 48-bit address" from the PanId and Short Address The form is PanId : 0x0 : 0x0 : ShortAddress.

The address follows RFC 4944, section 6, and it is used to build an Interface ID.

The Interface ID should have its U/L bit is set to zero, to indicate that this interface ID is not globally unique. However, the U/L bit flipping is performed when the IPv6 address is created.

As a consequence, here we set it to 1.

Parameters

panId	The PanID
shortAddr	The Short MAC address

Returns: a Pseudo-Mac48Address

Here is the caller graph for this function:

◆ GetMulticast() [1/2]

Address ns3::lrwpan::LrWpanNetDevice::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

multicastGroup The 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.
