test_ECMP is a test experiment to compare the transmitting performance of ECMP and PureSDN.
The following softwares should have been installed in your machine.
- Mininet: git clone git://github.com/mininet/mininet; mininet/util/install.sh -a
- Ryu: git clone git://github.com/osrg/ryu.git; cd ryu; pip install .
- Networkx: pip install networkx
- Numpy: pip install numpy
- Matplotlib: apt-get install python-matplotlib
To register parsing parameters, you NEED to add the following code into the end of ryu/ryu/flags.py.
CONF.register_cli_opts([
# k_shortest_forwarding
cfg.IntOpt('k_paths', default=4, help='number of candidate paths of KSP.'),
cfg.StrOpt('weight', default='bw', help='weight type of computing shortest path.'),
cfg.IntOpt('fanout', default=4, help='switch fanout number.')])
You must reinstall Ryu, so that you can run the new code. In the top directory of Ryu project:
sudo python setup.py install
Note: Before doing the experiment, you should change the controller's IP address from '192.168.56.101' to your own machine's eth0 IP address in the fattree.py module in each application, because '192.168.56.101' is my computer's eth0 IP address (Try 'ifconfig' in your Ubuntu to find out the eth0's IP address). Otherwise, the switches can't connect to the controller.
Just start it as follows, you will find the results in the 'results' directory. It will takes you about 70 hours.
$ ./run_experiment.sh 4 2.0 60
