"Python Network Programming Cookbook, 2nd Edition" ISBN: 1786463997 | 2017 | PDF | 442 pages | 15.41 MB Key Features Solve real-world tasks in the area of network programming, system/networking administration, network monitoring, and more Familiarize yourself with the fundamentals and functionalities of SDN Improve your skills to become the next-gen network engineer by learning the various facets of Python programming Book Description Python is an excellent language to use to write code and have fun by prototyping applications quickly. The presence of lots of third-party libraries, also known as batteries, makes it easier and faster to prototype an application or to implement a new algorithm. If you are interested in creating the building blocks for many practical web and networking applications that rely on networking protocols, then this book is a must-have. It employs Python for network programming to solve a variety of problems. This book highlights the major aspects of network programming in Python, starting from writing simple networking clients to developing complex Software-Defined Networking (SDN) systems and programming the Internet. 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, system and network 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 and other alternative vendor-specific SDN approaches and frameworks. You will also learn to configure the Linux Foundation networking ecosystem and automate your networks with Python. By the end of this book, you will be able to a
