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.

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 greatly improved the database and poller performance in the backend.

Released in 2001, Cacti (https://en.wikipedia.org/wiki/Cacti_(software)) is an open source web-based network monitoring and graphing tool designed as an improved frontend for...
