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.

Python for Cacti

In my early days working as a junior network engineer at a regional ISP, we used the open source cross-platform Multi Router Traffic Grapher (MRTG), (https://en.wikipedia.org/wiki/Multi_Router_Traffic_Grapher) tool to check the traffic load on network links. We relied on the tool almost exclusively for traffic monitoring. I was really amazed at how good and useful an open source project could be. It was one of the first open source high-level network monitoring systems that abstracted the details of SNMP, the database, and HTML for network engineers. Then came the Round-Robin Database Tool (RRDtool), (https://en.wikipedia.org/wiki/RRDtool). In its first release in 1999, it was referred to as "MRTG Done Right". It had greatly improved the database and poller performance in the backend.
