This software has the role of establishing flows in a Mininet
emulated network, with the help of the Floodlight controller.

In order to get a working example follow these steps:

1 - Download and install VirtualBox from
	https://www.virtualbox.org/wiki/Downloads
	
2 - Download the VirtualBox appliance from
	http://webdav.upm.ro/OptimalFlowDemo.ova
	File size is 2GB.
	
3 - Open VirtualBox, File -> Import Appliance..., browse to the downloaded
	appliance, click Next, then Import.
	
4 - Once importing is done in VirtualBox, click the imported appliance,
	then Settings -> Network, check Enable Network Adapter, on the right
	of "Attached to:" select Bridget Adapter, click ok, start the
	virtual machine. Credentials are the same for both username and password:
	optimalflow
	
5 - connect to the machine with SSH, in case of windows use	PuTTY,
	download link for PuTTY:
	http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
	
6 - After opening an SSH connection, type:
	sudo su
	password is optimalflow
	change directory to OptimalFlowSingleDomaingExperiment
	execute the file:run_floodlight.sh
	do not close the SSH connection
	
7 - Open a second SSH connection, type:
	sudo su
	password is optimalflow
	change directory to OptimalFlowSingleDomaingExperiment
	execute the file:oned_controllers.py
	do not close the SSH connection
	
8 - Run the setup for this application located in NetworkConfigurator Setup
	folder. You need the .NET framework, probably the newest version.
	
9 - Start the application, either by shortcut created on the desktop,
	or from the folder where you installed it.
	Click Open -> XML, browse to the Sample files folder
	and select the SingleDomainConfiguration.xml file.
	
10 -Click View -> All Flows, to view all the configured flows. If you want to,
	remove them all.

11 -In the application, to establish a flow between two hosts, hold down CTRL,
	all hosts should have a thicker border, if not, click once anywhere near
	a host,	so that the area receives focus. While holding CTRL, click
	on two hosts, a window pops up where you can set the protocol,
	whether or not the flow	is bidirectional and throughput.
	For your information, all links have a bandwidth of 100MB/s,
	you can change this by right clicking a link, then Edit.
	
12 -After setting the desired flows, get the IP address of your VM,
	it's the one used for SSH. In the Network Configurator application menu,
	click Flows	and there type http://192.168.0.102:8080
	Replace the IP address with the one of your VM.
	
13 -Click Push Flows, a dialog box will pop up to notify you about the 
	result of the operation.
	
14 -Go into the second SSH connection and test if the configured flows
	are working by typing for example:
	h1 ping h2
	assuming you have set the flow between these hosts.
