Detailed Description

This devices implements the following features:


  • layer 3 protocol multiplexing
  • MAC addressing
  • Aloha MAC:
    • packets transmitted as soon as possible
    • a new packet is queued if previous one is still being transmitted
    • no acknowledgements, hence no retransmissions
  • can support any PHY layer compatible with the API defined in generic-phy.h

Config Paths

ns3::AlohaNoackNetDevice is accessible through the following paths with Config::Set and Config::Connect:

  • "/NodeList/[i]/DeviceList/[i]/$ns3::AlohaNoackNetDevice"

Attributes

TraceSources

    Callback signature: ns3::Packet::TracedCallback
  • MacTxDrop: Trace source indicating a packet has been dropped by the device before transmission
    Callback signature: ns3::Packet::TracedCallback
  • MacPromiscRx: A packet has been received by this device, has been passed up from the physical layer and is being forwarded up the local protocol stack. This is a promiscuous trace,
    Callback signature: ns3::Packet::TracedCallback
  • MacRx: A packet has been received by this device, has been passed up from the physical layer and is being forwarded up the local protocol stack. This is a non-promiscuous trace,

Member Function Documentation

◆ AddLinkChangeCallback()

void ns3::AlohaNoackNetDevice::AddLinkChangeCallback ( Callback< void >  callback)
virtual
Parameters
callbackthe 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.

◆ DoDispose()

void ns3::AlohaNoackNetDevice::DoDispose ( void  )
privatevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden 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.

◆ GetAddress()

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

Implements ns3::NetDevice.

References m_address, and NS_LOG_FUNCTION.

◆ GetBroadcast()

Address ns3::AlohaNoackNetDevice::GetBroadcast ( void  ) const
virtual

◆ GetChannel()

Ptr< Channel > ns3::AlohaNoackNetDevice::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.

◆ GetMulticast() [1/2]

Address ns3::AlohaNoackNetDevice::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
multicastGroupThe 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.
