\subsubsection{Message levels}
\label{subsubsec:message_levels}
+ The \gls{osc} interface conceived in the course of this work implements
+ several message levels to be able to distinguish between types of
+ clients and servers.\\
+ The \textit{enumeration class} MessageLevel in
+ \textit{src/ssr\_global.h} defines the four types \textit{SERVER},
+ \textit{THIN\_CLIENT}, \textit{CLIENT}, \textit{GUI\_CLIENT}.\\
+ Client \gls{ssr} instances subscribe to (\gls{ssr}) server instances
+ with the \textit{MessageLevel} \textit{CLIENT} by default.\\
+ Several updating messages, such as information on \gls{cpu} load or master
+ signal level are not of interest to a rendering client and should
+ therefore not be sent to them, which is why they are only sent to
+ clients with a \textit{MessageLevel} of \textit{GUI\_CLIENT} connected
+ to a \gls{ssr} instance.\\
+ Lightweight \gls{osc} capable applications used to control a \gls{ssr}
+ server instance or mimicing the behavior of a server instance to
+ control a set of clients also don't need all the processing and
+ transport related information of clients sent to them, which is why
+ they ought to subscribe to them with the \textit{MessageLevel}
+ \textit{THIN\_CLIENT}.\\
+ Server instances subscribed to, get the \textit{MessageLevel}
+ \textit{SERVER} assigned to by each client by default. To change the
+ type of \gls{osc} messages sent to them, the server's
+ \textit{MessageLevel} can be set to a higher value (i.e.
+ \textit{THIN\_CLIENT}).
