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.

Config Paths

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

  • "/NodeList/[i]"

Attributes

No TraceSources are defined for this type.
Group: Network

Size of this type is 160 bytes (on a 64-bit architecture).
