ns-3

Overview

ns-3

is a discrete-event network simulator oriented towards network research and education, with a special focus on Internetbased

systems. The

ns-3 project is designing a follow-on successor to the popular ns-2 simulator.

In

ns-2, simulation scripts are written in OTcl. In ns-3, simulation scripts are written in C++, with support for extensions

that allow simulation scripts to be written in Python. These Python bindings have yet to be written, but the goal is for full or

near-full API support at the Python level.

ns-3

is intended to provide better support than in ns-2 for the following items:

•

Modularity of components

•

Scalability of simulations

•

Integration/reuse of externally developed code and software utilities

•

Emulation• Tracing and statistics
