We are going to write three different controllers:6 This is a simple !OpenFlow tutorial that will guide you through the writing of simple !OpenFlow controllers to showcase some of the !OpenFlow capabilities. We are going to write three different controllers: 7 7 1. Write a controller that will '''duplicate all the traffic''' of the !OpenFlow switch out a specific port 8 2. ''' TCP Port Forward''' controller. Diver geall traffic destined to host A on TCP port X to TCP port Y9 3. '''Proxy Controller'''. Write a controller that will diver geall traffic destined to host A, TCP port X to host B, TCP port Y8 2. ''' TCP Port Forward''' controller. Divert all traffic destined to host A on TCP port X to TCP port Y 9 3. '''Proxy Controller'''. Write a controller that will divert all traffic destined to host A, TCP port X to host B, TCP port Y 10 10 11 In this tutorial we are going to use [http://openvswitch.org/ Open vSwitch (OVS)] as an !OpenFlow switch connected to three hosts. 12 OVS is a software switch running on a compute resource. The other three hosts can only communicate through the OVS switch. Although the controller for the switch can run anywhere in the Internet, we are going to run it on the same host as the OVS switch to minimize the required resources. 13 For this tutorial we are going to use the [http://osrg.github.io/ryu/ Ryu controller], this is just an example of [wiki:OpenFlow/Controllers many controllers]. 11 In this tutorial we are using the '''''!OpenFlow Software Switch''''', [http://openvswitch.org/ Open vSwitch (OVS)]. The general topology is as pictured below. In general, the controller just needs to have a public IP address, so that it can exchange messages with the !OpenFlow switch. The controller for the switch can run anywhere in the Internet. 12 For this tutorial we are going to use a [http://osrg.github.io/ryu/ Ryu controller], which is just one example of [wiki:OpenFlow/Controllers many controller frameworks]. 14 13 15 [[Image(GENIExperimenter/Graphics: simple_ovs.png)]]14 [[Image(GENIExperimenter/Graphics:SimpleOpenFlow.jpg,40%)]] 16 15 17 16 == Prerequisites: == 18 17 - A GENI account, if you don't have one [wiki:SignMeUp sign up!] 19 - Familiarity with how to reserve GENI resources with any of the GENI Tools (GENI Experimenter Portal, Omni, Flack).
