The following instructions are for installing the ODL controller on Ubuntu version 13.04.

= Installing the ODL Controller =

The SDN controller used in the MF SDN prototype is the Open Daylight Controller. The release version is Hydrogen and we use the Base edition.

Required Packages

{{{
sudo apt-get update
sudo apt-get install git maven openjdk-7-jdk openjdk-7-jre
}}}
The pre-built version of the controller can be downloaded at the following link [http://nexus.opendaylight.org/content/repositories/opendaylight.release/org/opendaylight/integration/distributions-base/0.1.1/distributions-base-0.1.1-osgipackage.zip Open Dayligth Controller Hydrogen Base Edition]

Download and unzip the controller in a Linux machine. The controller was tested to work in Ubuntu 13.04.

{{{
unzip distributions-base-0.1.1-osgipackage.zip
}}}

= Developing !OpenFlow 1.3 Modules with the Controller =

For developing applications and running the controller with OF 1.3, download the openflowplugin from git at the following link:

{{{
git clone https://git.opendaylight.org/gerrit/p/openflowplugin.git
}}}
A sample application for a Learning switch is provided by the plugin. For learning to develop new modules as applications, this is a good starting point.

Build the application:

{{{
cd  openflowplugin/samples/learning-switch/
mvn clean install
}}}
For running the learning switch application,do the following steps

{{{
rm opendaylight/plugins/org.opendaylight.controller.samples.simpleforwarding-0.4.1.jar
}}}
Copy the 'learning-switch-0.0.3-SNAPSHOT.jar' bundle into the ‘opendaylight/plugins' folder.

To run the controller with OF 1.3:

{{{
cd opendaylight

./run.sh -of13
}}}
To test if the learning switch is working, on the controller console:

{{{
osgi > lb learn
}}}
Now you can see the controller installing flow rules when you test the network by pinging nodes.
