SDN Platform

This repository contains an advanced SDN controller and platform for network virtualization.

Building

Install prerequisites. You'll just need a basic functioning build environment plus a few build-time dependencies. On Ubuntu, you can run:

sudo apt-get install unzip python-dev python-virtualenv \
	 git openjdk-7-jdk ant build-essential

Note that on Ubuntu 12.04, you may want to remove java6:

sudo apt-get remove openjdk-6-jre-lib openjdk-6-jre-headless

To build the controller:

1. Clone from repository
2. ./setup.sh
3. make

Running

Sdncon

To run the controller and the cli, you need to be running a working instance of cassandra and sdncon. The setup script will have created a python virtualenv for you to make it easy to run the python components. You must first activate the virtualenv in your current shell by running

source ./workspace/ve/bin/activate

Now you can easily run any of the python commands.

The make targets start-cassandra and start-sdncon will automatically start a local copy of cassandra and sdncon. There are corresponding stop commands as well. These commands require an activated virtualenv. If you run

make stop-sdncon reset-cassandra start-sdncon

This will stop any existing sdncon and cassandra, reset their databases to zero, and start a new sdncon with a fresh database. The output from these commands will go to a log file in your workspace/ve/logs directory.

Controller

Now you're ready to run a copy of sdnplatform. The easiest way is to run

make start-sdnplatform

or you can do this manually with output to standard out by running from the sdnplatform directory

java -jar target/sdnplatform.jar

You can specify your own configuration file with -cf [path] or use the default.

CLI

The CLI depends on a running instance of sdncon. To run the CLI, just run it from the command line from the CLI directory:

./cli.py

The CLI has online help and tab completion on its commands.

Web-Dashboard

The example web-dashboard application depends on a running instance of sdncon and a web server to serve content. The web-dashboard files are divided into two parts:

document-root: Static HTML, javascript, and css files.
cgi-bin-root : Python based CGI scripts.

To run the web-dashboard, copy the files into the an apropriate webserver directory for the content type.

On Ubuntu 12.04 with a default Apache2 install:

1. Move document-root contents into /var/www
2. Move cgi-bin-root contents into /usr/lib/cgi-bin

If the webserver does not use /cgi-bin for CGI file access, modify the CGI_PATH variable in the dashboard.html file to the apropriate path.

Eclipse environment

1. At the shell, create the .project files with make eclipse % make eclipse

2. In Eclipse, create a new workspace: Click File -> Switch WorkSpace -> Other and then enter the name of the new workspace, e.g. "Workspace.net-virt-platform"

3. Once in the new workspace, import all of the eclipse projects Click File -> Import -> General -> Existing Projects into Workspace -> Next in the "Select Root Directory" dialog, type in or navigate to your checkout of the net-virt-platform base directory, e.g., ~/git/net-virt-platform .

Eclipse should automatically find four eclipse projects:

• cli
• django_cassandra_backend
• sdncon
• sdnplatform Make sure they are all checked (the default) and click "Finish"

If you are looking to do python development, it is recommended that you install the Eclipse "pydev" modules, as documented at http://pydev.org.
