Mastering Python Networking - Second Edition

By: Eric Chou

Overview of this book

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In this second edition of Mastering Python Networking, you’ll embark on a Python-based journey to transition from traditional network engineers to network developers ready for the next-generation of networks. This book begins by reviewing the basics of Python and teaches you how Python can interact with both legacy and API-enabled network devices. As you make your way through the chapters, you will then learn to leverage high-level Python packages and frameworks to perform network engineering tasks for automation, monitoring, management, and enhanced security. In the concluding chapters, you will use Jenkins for continuous network integration as well as testing tools to verify your network. By the end of this book, you will be able to perform all networking tasks with ease using Python.

Network resource API

Often, your network consists of network devices that do not change a lot once put into production. For example, you would have core devices, distribution devices, spine, leaf, top-of-rack switches, and so on. Each of the devices would have certain characteristics and features that you would like to keep in a persistent location so that you can easily retrieve them later on. This is often done in terms of storing data in a database. However, you would not normally want to give other users, who might want this information, direct access to the database; nor do they want to learn all the complex SQL query language. For this case, we can leverage Flask and the Flask-SQLAlchemy extension of Flask.

You can learn more about Flask-SQLAlchemy at http://flask-sqlalchemy.pocoo.org/2.1/.
