Python Network Programming - ebook

Power up your network applications with Python programming

Key Features

• Master Python skills to develop powerful network applications
• Grasp the fundamentals and functionalities of SDN
• Design multi-threaded, event-driven architectures for echo and chat servers

Book Description

This Learning Path highlights major aspects of Python network programming such as writing simple networking clients, creating and deploying SDN and NFV systems, and extending your network with Mininet. You’ll also learn how to automate legacy and the latest network devices. As you progress through the chapters, you’ll use Python for DevOps and open source tools to test, secure, and analyze your network. Toward the end, you'll develop client-side applications, such as web API clients, email clients, SSH, and FTP, using socket programming.

By the end of this Learning Path, you will have learned how to analyze a network's security vulnerabilities using advanced network packet capture and analysis techniques.

This Learning Path includes content from the following Packt products:

• Practical Network Automation by Abhishek Ratan
• Mastering Python Networking by Eric Chou
• Python Network Programming Cookbook, Second Edition by Pradeeban Kathiravelu, Dr. M. O. Faruque Sarker

What you will learn

• Create socket-based networks with asynchronous models
• Develop client apps for web APIs, including S3 Amazon and Twitter
• Talk to email and remote network servers with different protocols
• Integrate Python with Cisco, Juniper, and Arista eAPI for automation

Pradeeban Kathiravelu is an open source evangelist. He is a Ph.D. researcher at INESC-ID Lisboa/Instituto Superior Tecnico, Universidade de Lisboa, Portugal, and Universite Catholique de Louvain, Belgium. He is a fellow of Erasmus Mundus Joint Degree in Distributed Computing (EMJD-DC), researching a software-defined approach to quality of service and data quality in multi-tenant clouds. Pradeeban holds a bachelor's degree in engineering, from the University of Moratuwa, Sri Lanka and a master's degree in science, Erasmus Mundus European Master in Distributed Computing (EMDC), from Instituto Superior Tecnico, Portugal and KTH Royal Institute of Technology, Sweden. His research interests include software-defined networking, distributed systems, cloud computing, web services, big data in biomedical informatics, network functions virtualization, and data mining. He is interested in open source software development and has been an active participant in the Google Summer of Code (GSoC) program since 2009, as a student and as a mentor. Pradeeban has published several conference papers and co-authored a few book chapters. He has also worked on the OpenDaylight Cookbook and the Learning OpenDaylight as a technical reviewer. Python Network Programming Cookbook, Second Edition (2017) is his first book as an author. Dr. M. O. Faruque Sarker is a software architect, who received his Ph.D. in multi-robot systems from the University of South Wales. Currently, he works at the University College London, where he shapes various Linux and open source software solutions, mainly on cloud computing platforms, for commercial companies, educational institutions, and multinational consultancies. Over the past 10 years, he has led several Python software development and cloud infrastructure automation projects. In 2009, when he started using Python, he was responsible for shepherding a fleet of miniature E-puck robots at the University of South Wales, Newport, UK. Later, he honed his Python skills and was invited to work on the Google Summer of Code (2009/2010) programs for contributing to the BlueZ and Tahoe-LAFS open source projects. He is the author of Python Network Programming Cookbook and Learning Python Network Programming books both by Packt Publishing.
