# FORK NOTES EXPERIMENTAL FORK

Execution of test szenarios: - Test topologies in mininet/testbed* - Test controllers in dragonflow/tests/df_standalone

Example: - Startup controller1: vagrant up controller1 - Install requirements.txt and test-requirements.txt with pip. - Startup a Redis cluster (inside docker-redis-cluster folder): make run - Startup the switch (inside the mininet folder, mininet needs to be run as root): ./python-sudo testbed0/scratchnet_...ipv4.py - Startup the controller (starting l2_app_concept2.py): python2 dragonflow/tests/df_standalone/test_run_standalone.py

## Fixes - Fix for Redis to work with docker containers for testing:

```python

177: # FIX for work with docker redis cluster 178- # cluster nodes returns docker container ip 179- # This ip is not reachable from remote host 180- # Replacing containter IP with host ip 181- default_ip_port = self.redisMgt.keys()[0] 182- _, port = ip_port.split(':') 183- ip_default, _ = default_ip_port.split(':') 184- ip_port = "{}:{}".format(ip_default, port)

Overview

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

Distributed Dragonflow

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

Configurations

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
