PyTorch implementation of our paper "DRL-SFCP: Adaptive Service Function Chains Placement with Deep Reinforcement Learning" which is accepted by ICC 2021.

Note: This algorithm has been integrated into Virne, a NFV simulator, where you can find more details.

# only cpu
bash install.sh -c 0

# use cuda (optional version: 10.2, 11.3)
bash install.sh -c 11.3

python main.py --solver_name=$SOLVER_NAME

Here, you can choose SOLVER_NAME from a3c_gcn_seq2seq, grc_rank, mcts, etc. And you can find more detailed usage in main.py and config.py.

Please refer to settings/p_net_setting.yaml and settings/v_sim_setting.yaml for more details.
