Mastering Python Networking - Third 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 Mastering Python Networking, Third edition, 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 new edition is completely revised and updated to work with Python 3. In addition to new chapters on network data analysis with ELK stack (Elasticsearch, Logstash, Kibana, and Beats) and Azure Cloud Networking, it includes updates on using newer libraries such as pyATS and Nornir, as well as Ansible 2.8. Each chapter is updated with the latest libraries with working examples to ensure compatibility and understanding of the concepts. Starting with a basic overview of Python, the book teaches you how it can interact with both legacy and API-enabled network devices. You will learn to leverage high-level Python packages and frameworks to perform network automation tasks, monitoring, management, and enhanced network security followed by Azure and AWS Cloud networking. Finally, you will use Jenkins for continuous integration as well as testing tools to verify your network.

Review of TCP/IP Protocol Suite and Python

Welcome to the new exciting age of network engineering! When I started working as a network engineer at the turn of the millennium, the role was distinctly different than the network engineering role of today. At the time, network engineers mainly possessed domain-specific knowledge to manage and operate local and wide area networks using the command line interface. While they might occasionally cross over the discipline wall to handle tasks normally associated with systems administration and developers, there was no explicit expectation for a network engineer to write code or understand programming concepts. This is no longer the case today.

Over the years, the DevOps and Software–Defined Networking (SDN) movement, among other factors, have significantly blurred the lines between network engineers, systems engineers, and developers.
