NS-3 Overview
● Network Simulator version 3● Rewritten from scratch● An open source discrete event simulator
– Event model packet transmission , receipt , timers etc.
– Future events maintained in sorted Event List
– Processing events results in zero or more new events
● Developed for research and education.

NS-3 Basic
● Written in C++– Extensive use of Templates , Smart Pointer
Callback
– C++ namespace (ns3)
● Simulation programs are C++ executables● Python is used to bind public API's provided● NS3 is built as a library which may be linked
to a C++ main program defines the simulation topology and start the simulation.
