1.3 Overview
The RASADV Protocol is a simple, unidirectional, multicast protocol. The sender is a RAS server, which puts its machine name in a message and periodically multicasts it on its local network.<1> The receiver listens for periodic messages and passes the message content (the sender's machine name) and the source address to an application.<2> A typical application using the listener side of this protocol displays the information to the user.
