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:

TraceSources

MacTx: Trace source indicating a packet has arrived for transmission by this device
MacTxDrop: Trace source indicating a packet has been dropped by the device before transmission
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,

Member Function Documentation

void ns3::AlohaNoackNetDevice::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 297 of file aloha-noack-net-device.cc.

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

void ns3::AlohaNoackNetDevice::DoDispose ( void )

privatevirtual

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 117 of file aloha-noack-net-device.cc.

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

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

virtual

Returns: the current Address of this interface.

Implements ns3::NetDevice.

packet	packet sent from above down to Network Device
dest	mac address of the destination (already resolved)
protocolNumber	identifies the type of payload contained in this packet. Used to call the right L3Protocol when the packet is received.
