Chapter 13. Broadcasting with UDP

Communication would be inefficient if it always had to be accomplished between two individuals. Broadcasting, on the other hand, allows information to be disseminated to many recipients at once.

In this chapter, you will learn how to

  • Establish a broadcast UDP socket

  • Send broadcast messages with a socket

  • Receive broadcast messages with a socket

Upon completion of this chapter, you will know how to write programs using IPv4 socket broadcast facilities.
