2.2 Apollo components
Apollo comprises several client and server application which communicate via the Control Room Bus.
Server applications which manage resources such as projectors or the desktop of a Display Wall are installed and
used on central Server computers. These applications are started automatically during booting or log in.
The interactive client applications are graphical user interfaces to provide access to the services of the central
servers. If required they can started multiple times on each workstation of the Apollo network.
The Apollo Wall Management software consists of the following components:
Control Room Bus
The Apollo software runs distributed on different computers. The Control Room Bus supplies the communication
infrastructure for the computers integrated into the Apollo network. It also includes several system utilities and
an easy user interface. The Control Room Bus is based on the TCP/IP protocol and started automatically during
booting.
Desktop Server
This component runs on the control computer (TransForm A) of the Display Wall. It receives commands from the
interactive client applications of the workstations and converts them into activities to manipulate the windows of
the Display Wall.
Layout Editor
The Layout Editor is used to create and modify so-called layouts. Layouts usually consist of several windows
and/or shortcuts and define which windows are to be loaded in which position using what size. Every layout is
saved in a database using a unique name. Every Display Wall has its own database located on the associated
control computer or on any other network computer.
The Layout Editor is also used to define regions on the Display Wall. By means of regions, specific permissions
can be assigned to user groups.
Security Provider
The permissions of users to access and modify certain objects are controlled by Access Groups. An object can be
assigned to a number of Access Groups, each of which having individual permissions. Before a certain action is
performed, the permission of the user is checked. If the permission is given, the system will execute the action,
else not.
Checking is done by the Security Provider which is a separate party on the Control Room Bus.
SNMP Manager
The SNMP Manager is the interface between the Control Room Bus and the Simple Network Management Proto-
col (SNMP). The SNMP Manager provides the possibility to use a configuration file to integrate any SNMP-capable
device.
Explorer
The stand-alone applications Remote Desktop, Layout Selector and Device Manager are now integrated in one
application, the Apollo Explorer. Controlling a Display Wall now requires only launching the Apollo Explorer.
Remote Desktop
The Remote Desktop is integrated in the Explorer and enables to manipulate the windows of the Display Wall
from a separate and remote workstation.
If required, the user interface of the Explorer can be adapted to look like the user interface of the previous stand-
alone application Remote Desktop.
