Detailed Description

a NetDevice to read/write network traffic from/into a file descriptor.

A FdNetDevice object will read and write frames/packets from/to a file descriptor. This file descriptor might be associated to a Linux TAP/TUN device, to a socket or to a user space process, allowing the simulation to exchange traffic with the "outside-world"

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

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.

void ns3::FdNetDevice::DoDispose ( void )

protectedvirtual

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.

References m_mtu.

Address ns3::FdNetDevice::GetMulticast ( Ipv4Address multicastGroup ) const

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.

TracedCallback<Ptr<const Packet> > ns3::FdNetDevice::m_promiscSnifferTrace

private

A trace source that emulates a promiscuous mode protocol sniffer connected to the device.

This trace source fire on packets destined for any host just like your average everyday packet sniffer.

On the transmit size, this trace hook will fire after a packet is dequeued from the device queue for transmission. In Linux, for example, this would correspond to the point just before a device hard_start_xmit where dev_queue_xmit_nit is called to dispatch the packet to the PF_PACKET ETH_P_ALL handlers.

On the receive side, this trace hook will fire when a packet is received, just before the receive callback is executed. In Linux, for example, this would correspond to the point at which the packet is dispatched to packet sniffers in netif_receive_skb.
