Detailed Description

A network Node.

This class holds together:

a list of NetDevice objects which represent the network interfaces of this node which are connected to other Node instances through Channel instances.
a list of Application objects which represent the userspace traffic generation applications which interact with the Node through the Socket API.
a node Id: a unique per-node identifier.
a system Id: a unique Id used for parallel simulations.

Every Node created is added to the NodeList automatically.

Member Typedef Documentation

typedef Callback<void,Ptr<NetDevice>, Ptr<const Packet>,uint16_t,const Address &, const Address &, NetDevice::PacketType> ns3::Node::ProtocolHandler

A protocol handler

Parameters:

	device	a pointer to the net device which received the packet
	packet	the packet received
	protocol	the 16 bit protocol number associated with this packet. This protocol number is expected to be the same protocol number given to the Send method by the user on the sender side.
	sender	the address of the sender
	receiver	the address of the receiver; Note: this value is only valid for promiscuous mode protocol handlers.
	packetType	type of packet received (broadcast/multicast/unicast/otherhost); Note: this value is only valid for promiscuous mode protocol handlers.

Constructor & Destructor Documentation

ns3::Node::Node ( )

Must be invoked by subclasses only.

ns3::Node::Node ( uint32_t systemId )

Parameters:

systemId

a unique integer used for parallel simulations.

Must be invoked by subclasses only.

Member Function Documentation

uint32_t ns3::Node::AddApplication ( Ptr< Application > application )

Parameters:

application

Application to associate to this node.

Returns:: the index of the Application within the Node's list of Application.

Associated this Application to this Node. This method is called automatically from Application::Application so the user has little reasons to call this method directly.

uint32_t ns3::Node::AddDevice ( Ptr< NetDevice > device )

Parameters:

device

NetDevice to associate to this node.

Returns:: the index of the NetDevice into the Node's list of NetDevice.

Associate this device to this node.

static bool ns3::Node::ChecksumEnabled ( void ) [static]

Returns:: true if checksums are enabled, false otherwise.

virtual void ns3::Node::DoDispose ( void ) [protected, virtual]

The dispose method. Subclasses must override this method and must chain up to it by calling Node::DoDispose at the end of their own DoDispose method.

Reimplemented from ns3::Object.

Ptr<Application> ns3::Node::GetApplication ( uint32_t index ) const

Parameters:

index

Returns:: the application associated to this requested index within this Node.

Ptr<NetDevice> ns3::Node::GetDevice ( uint32_t index ) const

Parameters:

index

the index of the requested NetDevice

Returns:: the requested NetDevice associated to this Node.

The indexes used by the GetDevice method start at one and end at GetNDevices ()

uint32_t ns3::Node::GetId ( void ) const

Returns:: the unique id of this node.

This unique id happens to be also the index of the Node into the NodeList.

uint32_t ns3::Node::GetNApplications ( void ) const

Returns:: the number of applications associated to this Node.

uint32_t ns3::Node::GetNDevices ( void ) const

Returns:: the number of NetDevice instances associated to this Node.

uint32_t ns3::Node::GetSystemId ( void ) const

Returns:: the system id for parallel simulations associated to this node.

static TypeId ns3::Node::GetTypeId ( void ) [static]

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

This object is accessible through the following paths with Config::Set and Config::Connect:

/NodeList/[i]

Attributes defined for this type:

DeviceList: The list of devices associated to this Node.
- Set with class: ns3::ObjectVectorValue
- Underlying type: ns3::Ptr< ns3::NetDevice >
- Flags: read
ApplicationList: The list of applications associated to this Node.
- Set with class: ns3::ObjectVectorValue
- Underlying type: ns3::Ptr< ns3::Application >
- Flags: read
Id: The id (unique integer) of this Node.
- Set with class: ns3::UintegerValue
- Underlying type: uint32_t 0:4294967295
- Flags: read

No TraceSources defined for this type.

Reimplemented from ns3::Object.

virtual void ns3::Node::NotifyDeviceAdded ( Ptr< NetDevice > device ) [private, virtual]

Parameters:

device

the device added to this Node.

This method is invoked whenever a user calls Node::AddDevice.

void ns3::Node::RegisterProtocolHandler	(	ProtocolHandler	handler,
		uint16_t	protocolType,
		Ptr< NetDevice >	device,
		bool	promiscuous = `false`
	)

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 on this node.
	promiscuous	whether to register a promiscuous mode handler

void ns3::Node::UnregisterProtocolHandler ( ProtocolHandler handler )

Parameters:

handler

the handler to unregister

After this call returns, the input handler will never be invoked anymore.
