Overview

Fast Network Simulation Setup (FNSS) is a toolchain allowing network researchers and engineers to simplify the process of setting up a network experiment scenario. It allows users to:

• Parse a topology from a dataset or a topology generator or generate it according to a number of synthetic models
• Configure links with capacity, weights, delays and buffer sizes
• Deploy applications and protocol stacks on nodes
• Generate traffic matrices
• Generate event schedules
• Deploy network and workload configuration to a number of simulators and emulators

FNSS comprises acore library (written in Python) and a set of adapters. The core library provides all capabilities for generating the experiment scenario. The adapters allow users to export scenarios generated with the core library tons-2,ns-3,Mininet,Omnet++,Autonetkit andjFed as well other simulators or emulators through the Python core library itself or the providedJava andC++ libraries.

Usage

To use FNSS you would normally use the following workflow.

1. Create an experiment scenario (topology, traffic matrices, event schedules) using the Python core library.
2. Export the created scenario in your target simulator/emulator.
   • If your target simulator/emulator is ns-2, Mininet, Autonetkit or a Python program, the core library includes functions to export the scenario created in your target environment.
   • Otherwise, if you wish to run your experiments on ns-3 or a Java or C++ program, then export the scenario to XML files using the provided functions and use the Java, C++ or ns-3 library to import the scenario XML files into your target simulator/emulator.

Install

This section explains how to install the FNSS Python core library.

If you wish to use FNSS to deploy experiment scenarios in a C++ or a Java program or in the ns-3 simulator then you also need the relevant library, which you can download from the links further below.

Python pip

The easiest way to install the core Python library is to download it and install it from thePython Package Index. To do so, you must havePython installed on your machine andpip, which is a package manager for Python.

To install FNSS usingpip, you just need to run the following command:

$ pip fnss

Depending on the configuration of your machine you may need to runpip as superuser. Running this command will download the latest version of the FNSS core library and install it on your machine together with all required dependencies.

At this stage you are ready to use the Python core library. To use the Java or C++ APIs or the ns-3 adapters, please download the specific components that you need from the links below.

Virtual Machine

You can also run FNSS within a virtual machine.This repository contains scripts and documentation to set up a virtual machine with FNSS and all dependencies.

Libraries and adapters

You can download the latest stable releases of the C++ and Java libraries and ns-3 adapter from the following links:

Documentation and examples

Here you can find links to browse documentation and examples of the various components of the FNSS toolchain. Documentation and examples are also included in the component packages that can be downloaded from the links above.
