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> > ns3::Node::DeviceAdditionListener

A callback invoked whenever a device is added to a node.

private

Definition at line 223 of file node.h.

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. Note: If the L2 protocol does not use L2 addresses, the address reported here is the value of device->GetAddress().
packetType	type of packet received (broadcast/multicast/unicast/otherhost); Note: this value is only valid for promiscuous mode protocol handlers.

void ns3::Node::DoDispose ( void )

protectedvirtual

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.
