This document describes a simple TCP-based protocol for transporting VOEvent messages from authors, through brokers, to subscribers. The protocol has been in successful use on the VOEvent network for several years. Having been thus proven, the community needs a reference from which to implement it. This IVOA Note provides the information needed to implement the protocol to provide compatible communication in the VOEvent network.
