Member Function Documentation

void ns3::TrafficControlLayer::DeleteRootQueueDiscOnDevice ( Ptr< NetDevice > device )

virtual

This method can be used to remove the root queue disc (and associated filters, classes and queues) installed on a device.

Parameters

device the device on which the installed queue disc will be deleted

Definition at line 236 of file traffic-control-layer.cc.

References m_netDevices, NS_ASSERT_MSG, and NS_LOG_FUNCTION.

void ns3::TrafficControlLayer::DoDispose ( void )

protectedvirtual

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 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 69 of file traffic-control-layer.cc.

References ns3::Object::DoDispose(), m_handlers, m_netDevices, m_node, and NS_LOG_FUNCTION.

Here is the call graph for this function:

void ns3::TrafficControlLayer::DoInitialize ( void )

protectedvirtual

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

Reimplemented from ns3::Object.

Here is the caller graph for this function:

void ns3::TrafficControlLayer::NotifyNewAggregate ( void )

protectedvirtual

Notify all Objects aggregated to this one of a new Object being aggregated.

This function must be implemented in the stack that needs to notify other stacks connected to the node of their presence in the node.

This method is invoked whenever two sets of Objects are aggregated together. It is invoked exactly once for each Object in both sets. This method can be overriden by subclasses who wish to be notified of aggregation events. These subclasses must chain up to their base class NotifyNewAggregate() method.

It is safe to call GetObject() and AggregateObject() from within this method.

Reimplemented from ns3::Object.

void ns3::TrafficControlLayer::Receive	(	Ptr< NetDevice >	device,
		Ptr< const Packet >	p,
		uint16_t	protocol,
		const Address &	from,
		const Address &	to,
		NetDevice::PacketType	packetType
	)

virtual

Called by NetDevices, incoming packet.

After analyses and scheduling, this method will call the right handler to pass the packet up in the stack.

Parameters

device	network device
p	the packet
protocol	next header value
from	address of the correspondant
to	address of the destination
packetType	type of the packet

void ns3::TrafficControlLayer::RegisterProtocolHandler	(	Node::ProtocolHandler	handler,

Register an IN handler.

The handler will be invoked when a packet is received to pass it to upper layers.

Parameters

handler	the handler to register
protocolType	the type of protocol this handler is interested in. This protocol type is a so-called EtherType, as registered here: http://standards.ieee.org/regauth/ethertype/eth.txt the value zero is interpreted as matching all protocols.
device	the device attached to this handler. If the value is zero, the handler is attached to all devices.
