Running

1. Run the default example

Before running the example, you could update the configuration file in settings/ directory to set the parameters on simulation and algorithm.

python main.py

2. Run with custom configuration

Virne is built on Hydra, which allows you to override configuration parameters directly from the command line.

python main.py CONFIG_NAME=NEW_VALUE

Some examples of command line arguments are:

# Run with a specific nfv-ra algorithm
python main.py solver.solver_name=nrm_rank

# Run with a specific physical topology
python main.py p_net_setting.topology.file_path=../../datasets/topology/Geant.gml

# Run with a specific network system
python main.py system.if_offline_system=true
