Scenario: Provider networks with Open vSwitch¶ This scenario describes a provider networks implementation of the OpenStack Networking service using the ML2 plug-in with Open vSwitch (OVS). Provider networks generally offer simplicity, performance, and reliability at the cost of flexibility. The tutorial will be conducted by Srini Seetharaman. The June 11th tutorial will start with a brief introduction to OpenFlow/SDN, and then follow-up with a hands-on tutorial on the OpenDayLight OpenFlow controller. The tutorial will be similar to that conducted on April 30 and June 4.

We will be using a number of tools, namely Mininet, Open vSwitch, the OpenFlow Ryu controller, and Wireshark with the OpenFlow dissector. We can install each of these tools separately; however, it will take a while before we get everything installed and configured correctly. Luckily, SDN Hub (http://sdnhub.org) provides an all-in-one SDN app development starter VM (http://sdnhub.org/tutorials/sdn-tutorial-vm/) that includes all of the tools mentioned here and more. The base operating system is Ubuntu 14.04, which is similar to the VM that we have been using up to this point, and it also contains all the popular SDN controllers in one setting, such as OpenDaylight, ONOS, Ryu, Floodlight, POX, and Trema.
