Programming Linux sockets, Part 2: Using UDP

Writing UDP sockets applications in C and in Python

David Mertz (mertz@gnosis.cx), Developer, Gnosis Software
David Mertz
David Mertz has been writing the developerWorks columns Charming Python and XML Matters since 2000. Check out his book Text Processing in Python. For more on David, see his personal Web page.

Summary:  This intermediate-level tutorial extends the basics covered in Part 1 on programming using sockets. Part 2 focuses on the User Datagram Protocol (UDP) and demonstrates how to write UDP sockets applications in C and in Python. Although the code examples in this tutorial are in Python and C, they translate well to other languages.

Summary

The server and client presented in this tutorial are simple, but they show everything essential to writing UDP sockets applications in C and in Python. A more sophisticated client or server is, at heart, just one that transmits more interesting data back and forth; the sockets-level code is not much different for these.

The general outlines of performing threading, forking, and asynchronous socket handling are similarly applicable to more advanced servers. Your servers and clients themselves are likely to do more, but your strategies towards scalability will always be one of these three approaches (or a combination of them).
