The final section of Chapter 1, Review of TCP/IP Protocol Suite and Python Language, introduce to you another Python-based OpenFlow controller, POX. When OpenFlow was originally developed at Stanford, the original controller was NOX, written in Java. As an easier-to-learn alternative to NOX, POX was created. I personally used POX to learn OpenFlow a few years ago and thought it was an excellent learning tool. However, as time has passed, the development of POX seems to have slowed down a bit. For example, currently there is no active effort for Python 3. More importantly, officially, POX supports OpenFlow 1.0 and a number of Nicira extensions and has partial support for OpenFlow 1.1. Therefore, I have picked Ryu as the OpenFlow controller for this book. POX remains a viable alternative, however, for Python-based controllers if you are only working with OpenFlow...

Overview of this book
This book begins with a review of the TCP/ IP protocol suite and a refresher of the core elements of the Python language. Next, you will start using Python and supported libraries to automate network tasks from the current major network vendors. We will look at automating traditional network devices based on the command-line interface, as well as newer devices with API support, with hands-on labs. We will then learn the concepts and practical use cases of the Ansible framework in order to achieve your network goals.
We will then move on to using Python for DevOps, starting with using open source tools to test, secure, and analyze your network. Then, we will focus on network monitoring and visualization. We will learn how to retrieve network information using a polling mechanism, ?ow-based monitoring, and visualizing the data programmatically. Next, we will learn how to use the Python framework to build your own customized network web services.
In the last module, you will use Python for SDN, where you will use a Python-based controller with OpenFlow in a hands-on lab to learn its concepts and applications. We will compare and contrast OpenFlow, OpenStack, OpenDaylight, and NFV. Finally, you will use everything you’ve learned in the book to construct a migration plan to go from a legacy to a scalable SDN-based network.
