 Initially, each device queries the update server regularly for the current firmware version and initializes the update process if remote and local versions differ.
 To do so, the update server provides a file for each device type containing the available version identifier, which is stored beside the firmware binary files.
-These version identifier files are provided by the update server using \textit{HTTP 1.1}\cite{HTTP_1.1} under the following path pattern: \texttt{\${DEVICE}.version} (whereas \texttt{\${DEVICE}} is the device type name).

 The version identifier can be an arbitrary string as the content is not interpreted semantically but only compared to the version identifier used during build time.
 
 Each device tries to fetch the version identifier file once every hour.
