Not Overcomplicated Network Simulator

Overview

Not Overcomplicated Network Simulator (NoNS) is a free open source project aiming to build a discrete-event network simulator targeted at easy testing of congestion control algorithms.

Dependencies

NoNS need gnuplot & graphiz to generate plots, so install it:

sudo apt install --fix-missing gnuplot
sudo apt install --fix-missing graphviz

Other dependecies are designed as git submodules, so to install them, run

git submodule init
git submodule update --init --recursive

Build project

NoNS uses CMake build manager, so project builds in this way:

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

Run project

Build project and run it with -h option to see help.

Examples of configs that need to run NoNS are placed under configs directory. See config schemas here.

How to add a new congestion control algorithm

If you want to implement TCP-like algorithm, follow these steps:

1. Create class (YourCC further) that implements ITcpCC. It should be a class that contains all logic of your congestion control algorithm. See example: TcpTahoeCC.
2. Add implementation of parsing YourCC and put it to directory with tcp congestion control parsers and call it from common TCP congestion control parser

Results of simulations

Metrics and results of load testing of all simulation runs are deployed to GitHub Pages
