Detailed Description

Network layer to device interface.

This interface defines the API which the IP and ARP layers need to access to manage an instance of a network device layer. It currently does not support MAC-level multicast but this should not be too hard to add by adding extra methods to register MAC multicast addresses to filter out unwanted packets before handing them to the higher layers.

In Linux, this interface is analogous to the interface just above dev_queue_xmit() (i.e., IP packet is fully constructed with destination MAC address already selected).

If you want to write a new MAC layer, you need to subclass this base class and implement your own version of the pure virtual methods in this class.

This class was designed to hide as many MAC-level details as possible from the perspective of layer 3 to allow a single layer 3 to work with any kind of MAC layer. Specifically, this class encapsulates the specific format of MAC addresses used by a device such that the layer 3 does not need any modification to handle new address formats. This means obviously that the NetDevice class must know about the address format of all potential layer 3 protocols through its GetMulticast methods: the current API has been optimized to make it easy to add new MAC protocols, not to add new layer 3 protocols.

Devices aiming to support flow control and dynamic queue limits must perform the following operations:

in the NotifyNewAggregate method
- cache the pointer to the netdevice queue interface aggregated to the device
- set the select queue callback through the netdevice queue interface, if the device is multi-queue
anytime before initialization
- set the number of device transmission queues (and optionally create them) through the netdevice queue interface, if the device is multi-queue
when the device queues have been created, invoke NetDeviceQueueInterface::ConnectQueueTraces, which
- connects the Enqueue traced callback of the device queues to the PacketEnqueued static method of the NetDeviceQueue class
- connects the Dequeue and DropAfterDequeue traced callback of the device queues to the PacketDequeued static method of the NetDeviceQueue class
- connects the DropBeforeEnqueue traced callback of the device queues to the PacketDiscarded static method of the NetDeviceQueue class

Member Enumeration Documentation

◆ PacketType

enum ns3::NetDevice::PacketType

Packet types are used as they are in Linux.

GCC name resolution on typedef enum {} PacketType is broken for the foreseeable future, so if you need to use ns-3 PacketType in a driver that also uses the Linux packet types you're hosed unless we define a shadow type, which we do here.

PACKET_HOST	Packet addressed to us.
NS3_PACKET_HOST
PACKET_BROADCAST	Packet addressed to all.
NS3_PACKET_BROADCAST
PACKET_MULTICAST	Packet addressed to multicast group.

◆ AddLinkChangeCallback()

virtual void ns3::NetDevice::AddLinkChangeCallback ( Callback< void > callback )

pure virtual

Parameters

callback the callback to invoke

Add a callback invoked whenever the link status changes to UP. This callback is typically used by the IP/ARP layer to flush the ARP cache and by IPv6 stack to flush NDISC cache whenever the link goes up.

◆ GetMulticast() [1/2]

virtual Address ns3::NetDevice::GetMulticast ( Ipv4Address multicastGroup ) const

pure virtual

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.

pure virtual

Parameters

cb	callback to invoke whenever a packet has been received in promiscuous mode and must be forwarded to the higher layers.

Enables netdevice promiscuous mode and sets the callback that will handle promiscuous mode packets. Note, promiscuous mode packets means all packets, including those packets that can be sensed by the netdevice but which are intended to be received by other hosts.

Implemented in ns3::WimaxNetDevice, ns3::WifiNetDevice, ns3::UanNetDevice, ns3::NonCommunicatingNetDevice, ns3::AlohaNoackNetDevice, ns3::MockNetDevice, ns3::PointToPointNetDevice, ns3::SimpleNetDevice, ns3::LteNetDevice, ns3::LrWpanNetDevice, ns3::LoopbackNetDevice, ns3::CsmaNetDevice, ns3::VirtualNetDevice, ns3::TapBridge, ns3::SixLowPanNetDevice, ns3::OpenFlowSwitchNetDevice, ns3::MeshPointDevice, ns3::FdNetDevice, and ns3::BridgeNetDevice.

◆ SetReceiveCallback()

virtual void ns3::NetDevice::SetReceiveCallback ( ReceiveCallback cb )

pure virtual

Parameters

cb	callback to invoke whenever a packet has been received and must be forwarded to the higher layers.

Set the callback to be used to notify higher layers when a packet has been received.

Implemented in ns3::WimaxNetDevice, ns3::WifiNetDevice, ns3::VirtualNetDevice, ns3::UanNetDevice, ns3::TapBridge, ns3::NonCommunicatingNetDevice, ns3::AlohaNoackNetDevice, ns3::MockNetDevice, ns3::SixLowPanNetDevice, ns3::PointToPointNetDevice, ns3::OpenFlowSwitchNetDevice, ns3::SimpleNetDevice, ns3::MeshPointDevice, ns3::LteNetDevice, ns3::LrWpanNetDevice, ns3::LoopbackNetDevice, ns3::FdNetDevice, ns3::CsmaNetDevice, and ns3::BridgeNetDevice.

◆ SupportsSendFrom()

virtual bool ns3::NetDevice::SupportsSendFrom ( ) const

pure virtual

Returns: true if this interface supports a bridging mode, false otherwise.

Implemented in ns3::WimaxNetDevice, ns3::WifiNetDevice, ns3::VirtualNetDevice, ns3::UanNetDevice, ns3::TapBridge, ns3::NonCommunicatingNetDevice, ns3::AlohaNoackNetDevice, ns3::MockNetDevice, ns3::SixLowPanNetDevice, ns3::PointToPointNetDevice, ns3::OpenFlowSwitchNetDevice, ns3::SimpleNetDevice, ns3::MeshPointDevice, ns3::LteNetDevice, ns3::LrWpanNetDevice, ns3::LoopbackNetDevice, ns3::FdNetDevice, ns3::CsmaNetDevice, and ns3::BridgeNetDevice.
