Member Function Documentation

void ns3::UanNetDevice::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.

Definition at line 366 of file uan-net-device.cc.

References ns3::TracedCallback< T1, T2, T3, T4, T5, T6, T7, T8 >::ConnectWithoutContext().

void ns3::UanNetDevice::Clear ( void )

Clears all pointer references

Definition at line 51 of file uan-net-device.cc.

Referenced by DoDispose().

void ns3::UanNetDevice::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.

Reimplemented from ns3::Object.

Definition at line 82 of file uan-net-device.cc.

References Clear(), and ns3::Object::DoDispose().

Address ns3::UanNetDevice::GetAddress ( void ) const

virtual

Returns: the current Address of this interface.

Implements ns3::NetDevice.

Definition at line 221 of file uan-net-device.cc.

Address ns3::UanNetDevice::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.

Definition at line 254 of file uan-net-device.cc.

Ptr< Channel > ns3::UanNetDevice::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.

Definition at line 215 of file uan-net-device.cc.

uint32_t ns3::UanNetDevice::GetIfIndex ( void ) const

virtual

Returns: index ifIndex of the device

Implements ns3::NetDevice.

Definition at line 209 of file uan-net-device.cc.

Ptr< UanMac > ns3::UanNetDevice::GetMac ( void ) const

Returns: MAC this device is using

Definition at line 191 of file uan-net-device.cc.

uint16_t ns3::UanNetDevice::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.

Definition at line 236 of file uan-net-device.cc.

Address ns3::UanNetDevice::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.

Ptr< Node > ns3::UanNetDevice::GetNode ( void ) const
