Intro to OpenFlow Tutorial with Ryu Controller
Part 1: Design and Setup In this tutorial we are going to use Open vSwitch (OVS) as an OpenFlow switch connected to three hosts. OVS is a software switch running on a compute resource. The other three hosts can only communicate through the OVS switch. The experiment will need (the rspecs for this exercise are provided later in this section): 1 Xen VM with a public IP to run an OpenFlow controller 1 Xen VM to be the OpenFlow switch 3 Xen VMs as hosts Step 1: Reserve Resources Go to add resources and add RSpec using the URL option a) Reserve a VM that runs your OpenFlow controller. b) Reserve your network, that includes a VM with OVS installed. Step 2: Configure and Initialize Services Overview: Although OVS is installed and initialized on the host that is meant to act as a software switch, it has not been configured yet. There are two main things that need to be configured: (1) configure your software switch with the interfaces a...
