Hands-On Network Programming with C# and .NET Core

By: Sean Burns

Overview of this book

The C# language and the .NET Core application framework provide the tools and patterns required to make the discipline of network programming as intuitive and enjoyable as any other aspect of C# programming. With the help of this book, you will discover how the C# language and the .NET Core framework make this possible. The book begins by introducing the core concepts of network programming, and what distinguishes this field of programming from other disciplines. After this, you will gain insights into concepts such as transport protocols, sockets and ports, and remote data streams, which will provide you with a holistic understanding of how network software fits into larger distributed systems. The book will also explore the intricacies of how network software is implemented in a more explicit context, by covering sockets, connection strategies such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), asynchronous processing, and threads. You will then be able to work through code examples for TCP servers, web APIs served over HTTP, and a Secure Shell (SSH) client. By the end of this book, you will have a good understanding of the Open Systems Interconnection (OSI) network stack, the various communication protocols for that stack, and the skills that are essential to implement those protocols using the C# programming language and the .NET Core framework.

The Internet Protocol

In the previous chapter, we got a comprehensive understanding of two of the most common and robust protocols in the transport layer of the Open Systems Interconnection (OSI) network stack, with the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). In this chapter, we'll look at the network layer protocol that enables each of those two transport layer services. In this chapter, we'll be learning about the Internet Protocol (IP). We'll look at how the IP standard has evolved to support a global network of billions of devices, allowing each of them to reliably communicate with one another. We'll consider the earlier, and more common IPv4, looking at what problems IPv4 was designed to solve, and discussing the limitations that it has reached. Next, we'll examine how IPv6 aims to solve those limitations. Finally, we...
