Member Function Documentation

virtual void ns3::EmuNetDevice::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.

Implements ns3::NetDevice.

virtual Address ns3::EmuNetDevice::GetAddress ( void   )  const [virtual]
Returns:
the current Address of this interface.

Implements ns3::NetDevice.

virtual Address ns3::EmuNetDevice::GetBroadcast ( void   )  const [virtual]
Returns:
the broadcast address supported by this netdevice.

Calling this method is invalid if IsBroadcast returns not true.

Implements ns3::NetDevice.

virtual Ptr<Channel> ns3::EmuNetDevice::GetChannel ( void   )  const [virtual]
Returns:
the channel this NetDevice is connected to. The value returned can be zero if the NetDevice is not yet connected to any channel or if the underlying NetDevice has no concept of a channel. i.e., callers _must_ check for zero and be ready to handle it.

Implements ns3::NetDevice.

EmuNetDevice::EncapsulationMode ns3::EmuNetDevice::GetEncapsulationMode ( void   )  const

Get the encapsulation mode of this device.

Returns:
The encapsulation mode of this device.
virtual uint32_t ns3::EmuNetDevice::GetIfIndex ( void   )  const [virtual]
Returns:
index ifIndex of the device

Implements ns3::NetDevice.

virtual uint16_t ns3::EmuNetDevice::GetMtu ( void   )  const [virtual]
Returns:
the link-level MTU in bytes for this interface.

This value is typically used by the IP layer to perform IP fragmentation when needed.

Implements ns3::NetDevice.

virtual Address ns3::EmuNetDevice::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).

This method performs the multicast address creation function appropriate to an EUI-48-based CSMA device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact address format.

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.
See also:
Ipv4Address
Mac48Address
Address

Implements ns3::NetDevice.

virtual Address ns3::EmuNetDevice::GetMulticast ( Ipv6Address  addr  )  const [virtual]

Get the MAC multicast address corresponding to the IPv6 address provided.

Parameters:
addr IPv6 address
Returns:
the MAC multicast address
Warning:
Calling this method is invalid if IsMulticast returns not true.

Implements ns3::NetDevice.

virtual Ptr<Node> ns3::EmuNetDevice::GetNode ( void   )  const [virtual]
Returns:
the node base class which contains this network interface.

When a subclass needs to get access to the underlying node base class to print the nodeid for example, it can invoke this method.

Implements ns3::NetDevice.

Ptr<Queue> ns3::EmuNetDevice::GetQueue ( void   )  const

Get a copy of the attached Queue.

Returns:
Ptr to the queue.
static TypeId ns3::EmuNetDevice::GetTypeId ( void   )  [static]

This method returns the TypeId associated to ns3::EmuNetDevice.
