Communication between server and clients is done by exchanging packets over a [[channel (communications)|channel]]. The connection is established by the client (how the client is started is not specified in the protocol). The client also sends the first packet, containing the [[byte order]] to be used and information about the version of the protocol and the kind of authentication the client expects the server to use. The server answers by sending back a packet stating the acceptance or refusal of the connection, or with a request for a further [[authentication]]. If the connection is accepted, the acceptance packet contains data for the client to use in the subsequent interaction with the server.
