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.

Caching Strategies for Distributed Systems

In the previous chapter, we learned all about common patterns for applying security to a network-hosted application. In this chapter, we will look at various ways to improve the performance of our network software by establishing intermediate caches. We'll see how using a cache to persist frequently accessed highly available data can grant us those performance improvements. We'll look at what a cache is and some of the various ways it can be used. Then, we'll undertake a thorough examination of one of the most common and complex architectural patterns for network caches. Finally, we'll demonstrate how to use caching at various levels of the application architecture to achieve our goals with a reasonable balance of developer effort and latency reduction.

The following topics will be covered in this chapter:

  • The potential...
