Since a communication protocol is something a designer decides on for himself I am going to provide an answer assuming that you rather want to know about the communication interface.
See this nice tutorial / info here:

A guy called Nick Gammon posted a tutorial of his protocol to Arduinos together here:

An industry example would be the protocol to communicate with Pelco cameras:
