Python Network Programming Cookbook - Second Edition

By: Pradeeban Kathiravelu, Gary Berger, Dr. M. O. Faruque Sarker

Overview of this book

Python Network Programming Cookbook - Second Edition highlights the major aspects of network programming in Python, starting from writing simple networking clients to developing and deploying complex Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) systems. It creates the building blocks for many practical web and networking applications that rely on various networking protocols. It presents the power and beauty of Python to solve numerous real-world tasks in the area of network programming, network and system administration, network monitoring, and web-application development. In this edition, you will also be introduced to network modelling to build your own cloud network. You will learn about the concepts and fundamentals of SDN and then extend your network with Mininet. Next, you’ll find recipes on Authentication, Authorization, and Accounting (AAA) and open and proprietary SDN approaches and frameworks. You will also learn to configure the Linux Foundation networking ecosystem and deploy and automate your networks with Python in the cloud and the Internet scale. By the end of this book, you will be able to analyze your network security vulnerabilities using advanced network packet capture and analysis techniques.

Introduction

Authentication, authorization, and accounting (AAA) are the three major pillars of access control. Authentication identifies the user, authorization identifies the roles of the user, and accounting ensures that the user actions are performed within the usage limits (such as throttling). AAA, as they are collectively known, are crucial for networks for proper functioning and security. Hence network projects consider AAA as a crucial factor in their network architecture—remarkably the OpenDaylight's AAA project is considered to be a core project in the SDN controller ecosystem. In this chapter, we will look into the AAA options for networking, and how to configure AAA with Python for the networks. We start the chapter with simpler recipes before going into more complex ones.
