Network Programming

TCP/IP Fundamentals
BeginnerRust

In this course, you will learn how to work with the UDP and TCP internet protocols in real-world scenarios. You will apply your skills to build small, fun networking applications in Rust — right in your browser!

No previous knowledge of network programming is required, but we assume that you are familiar with Rust syntax. If you’re not, that's fine too! You can read The Rust Book and learn by practicing without any setup beforehand.

Number Encoding

Learn how to work with binary and hexadecimal numbers.

Exchanging Messages

Introduction to UDP: sockets, frames, and data encoding. We build a client for a simple name server that converts domain names into IP addresses.

Fragmentation

Learn how to transmit large files by splitting them into small bits.

Reliability

Learn how to deal with unreliable networks.

Routing

Learn how to work with larger networks. As you might have guessed, we also build our own router.

Server programming

Learn techniques to deal with multiple clients simultaneously. Remember the name service from the first lesson? Now we rebuild it again from scratch!

Introducing TCP

Learn about TCP connections and streams.

Web servers & HTTP

Putting everything we have learned so far into practice: let's create a web server!
