mknet

mknet is a tool to simulate various network topologies locally thanks to network namespaces and traffic control (tc).

Prepare your environment

Get the repository and its submodules:

git clone https://git.deuxfleurs.fr/Deuxfleurs/mknet.git
cd mknet
git submodule update --init

Compile benchmark tools:

( cd benchmarks/warp && go build )
( cd benchmarks/s3concurrent && go build )
( cd benchmarks/s3lat && go build )

Switch to root as it is required by our tool, and setup your python environment.

sudo -i
pip3 install --user .
( cd scenarios && pip3 install --user -r requirements.txt )

Sometimes, it is required to add manually your local python lib folder to the environment:

export PYTHONPATH=$PYTHONPATH:$HOME/.local/lib/python3.10/site-packages/

You can check that everything has been installed by running in a python REPL:

import garage_admin_sdk

Run a test

(Not yet implemented)

./mknet scenario ./scenarios/garage-s3lat ./topo/single-dc.yml
