Dragonflow implements Neutron using a lightweight embedded SDN Controller.

Our project mission is to Implement advanced networking services in a manner that is efficient, elegant and resource-nimble

Comprehensive agentless implementation of the Neutron APIs and advanced network services, such as fully distributed Switching, Routing, DHCP and more.

This configuration is the current focus of Dragonflow. Overview and details are available in the Distributed Dragonflow Section

To generate the sample dragonflow configuration files, run the following command from the top level of the dragonflow directory:

tox -e genconfig

If a 'tox' environment is unavailable, then you can run the following script instead to generate the configuration files:

./tools/generate_config_file_samples.sh
