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

To set up an eclipse environment:

  1. make eclipse to generate eclipse project files
  2. Import "sdnplatform" project into any eclipse workspace
