Mastering Python Networking

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.

Chapter 13. Hybrid SDN

It seems that software defined networking is on every network engineer's mind these days, and rightfully so. Ever since the introduction of OpenFlow in 2010, we have seen steady news on traditional networks transition to a software-defined network. The news typically focuses on the infrastructure agility as competitive advantage that the change brings. Many high profile SDN startups were formed offering new network services, such as SD-WAN. In the slower paced standards bodies, SDN standards were gradually being ratified. In the marketplace, vendors such as Quanta and Pica8 started to join forces in making carrier-grade hardware that was de-coupled from software. The combination of results is a seemingly new SDN world, just waiting around the corner for all networks to transition to. However, the reality is a bit different. Despite all the progress SDN have made, the technology deployment seems to be biased toward the very large, some might call Hyperscale, networks...
