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

The Transport Layer - TCP and UDP

In previous chapters, we've looked at the interactions of different application layer protocols and how to program those interactions in .NET Core. In this chapter, we'll go one step closer to the hardware and start looking at transport layer protocols with Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). We'll look at the connection-based and connectionless communication patterns that each implements, and we'll look at the strengths and weaknesses inherent to each approach. In addition, we'll examine how to write and interact with a software client that implements each protocol and use that to extend the functionality of our networked applications with custom behavior. Finally, we'll ...
