Software Defined Networking for Community Network Testbeds

As a closing post on this effort I present you the following contributions:

Poxy: A proxy for the OpenFlow controller – OpenFlow switch connection
Pongo: An POX application, integrated with Django, which allows handling of the topology of a mesh of nodes (currently customized for the Community-Lab testbed).

My thesis titled “Software Defined Networking for Community Network Testbeds” can be found here.

A paper titled “Software Defined Networking for Community Network Testbeds” in the 2nd International Workshop on Community Networks and Bottom-up-Broadband(CNBuB 2013).

Here you can find the presentation slides.

Thanks for following. Comming up more work about Community Networks.

Take care.

Fast start with Open vSwitch and POX controller in Debian Wheezy

Instructions mostly from the Open vSwitch Readme

Installation

// Delete all linux bridges that exist.
// then remove the bridge module
root@debian:/# modprobe -r bridge
// Install common and switch packages
root@debian:/# aptitude install openvswitch-switch openvswitch-common
// Install and build the ovs module using the DKMS package
root@debian:/# aptitude install openvswitch-datapath-dkms

Initialization

// Load the ovs module
root@debian:/# modprobe openvswitch_mod
// Create the configuration database
root@debian:/# ovsdb-tool create /var/lib/openvswitch/conf.db /usr/share/openvswitch/vswitch.ovsschema
// Start ovsdb-server without SSL support
root@debian:/# ovsdb-server --remote=punix:/var/run/openvswitch/db.sock --remote=db:Open_vSwitch,manager_options --pidfile --detach
// The next command should be run the firt time a database is created
// with the ovsdb-tool as we did above. It initializes the db
root@debian:/# ovs-vsctl --no-wait init
// Start ovs daemon
root@debian:/# ovs-vswitchd --pidfile --detach
// Create a bridge
root@debian:/# ovs-vsctl add-br br0

And we are ready to go!

Integrate POX with OVS

// Get Pox and move to the betta -current stable branch -
user@debian:~/$ git clone http://www.github.com/noxrepo/pox
user@debian:~/$ cd pox/
user@debian:~/pox/$ git checkout betta
// Start an empty controller, without templates where rules have to 
// be added manually
user@debian:~/pox/$ ./pox.py samples.pretty_log
// Go in another terminal
// Define the switch's policy if connection with the server is lost
// standalone or secure, see ovs-vsctl manual
root@debian:/# ovs-vsctl set-fail-mode ovs-switch standalone
// Define the controller  address to the switch
root@debian:/# ovs-vsctl set-controller br0 tcp:0.0.0.0:6633

Now everything is set up. Have fun 😛
