Detailed Description

Virtual net device modeling mesh point.

Mesh point is a virtual net device which is responsible for

Aggregating and coordinating 1..* real devices – mesh interfaces, see MeshInterfaceDevice class.
Hosting all mesh-related level 2 protocols.

One of hosted L2 protocols must implement L2RoutingProtocol interface and is used for packets forwarding.

From the level 3 point of view MeshPointDevice is similar to BridgeNetDevice, but the packets, which going through may be changed (because L2 protocols may require their own headers or tags).

void ns3::MeshPointDevice::AddLinkChangeCallback ( Callback< void > callback )

◆ DoDispose()

void ns3::MeshPointDevice::DoDispose ( )

It is safe to call GetObject() from within this method.

Here is the caller graph for this function:

◆ GetMulticast() [1/2]

Address ns3::MeshPointDevice::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.
