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.

Writing a chat server using select.select

Launching a separate thread or process per client may not be viable in any larger network server application where several hundred or thousand clients are concurrently connected to the server. Due to the limited available memory and host CPU power, we need a better technique to deal with a large number of clients. Fortunately, Python provides the select module to overcome this problem.

How to do it...

We need to write an efficient chat server that can handle several hundred or a large number of client connections. We will use the select() method from the select module that will enable our chat server and client to do any task without blocking a send or receive a call all the time.
