discrete event simulator targeted at networking research (documentation)
ns-2 is a discrete event-driven network simulator targeted at networking research. It provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.
An extensible simulation engine is implemented in C++ that uses MIT's Object Tool Command Language, OTcl (an object oriented version of Tcl) as the command and configuration interface. A previous version of the simulator i.e. ns version 1 used the Tool Command Language, Tcl as the configuration language. Ns-2 still supports simulation scripts written in Tcl meant for the ns version 1 simulator.
The simulator is invoked via the ns interpreter, an extension of the vanilla otclsh command shell. A simulation is defined by a OTcl script. The scripts use the Simulator Class as the principal interface to the simulation engine. Using the methods defined in this class, a network topology is defined, traffic sources and sinks are configured, the simulation is invoked, and the statistics are collected. By building upon a fully functional language, arbitrary actions can be programmed into the configuration.
Currently, ns-2 does not have an active development, all efforts moved to ns-3. Ns-2 still has models not implemented in ns-3, but if a new user does not need them, they may consider learning and using ns-3.
This package contains the documentation of ns-2.
