The pUser needs a JAVA-enabled browser in order to communicate with the data center. Access to the necessary applications and data is done via the Intranet or Internet. OSGD is deployed as an interposed service in this communication.

The communication between the workstation and OSGD is referred to as Adaptive Internet Protocol (AIP) and is tunneled in HTTPS. The AIP ensures optimal utilization through compression and optimization of the data and controls the safe use during Network failure. AIP thus allows for the use of graphical applications, even over narrowband connections.

During the course of communication a protocol break occurs on the OSGD server (AIP – X11, AIPRDP, AIPSSH), which leads to a physical separation. The pUser and the Applications are
thus in different security zones.

An application in the OSGD repository is defined in two steps. Firstly, the command with parameters and type of presentation, secondly the associated server(s). The application is then assigned either directly or indirectly to a pUser or a group of pUsers. The assignment is thereby conducted either statically or dynamically through LDAP / Active Directory (Directory Service Integration (DSI)).

The pUsers can be stored in the system either locally, or in the LDAP / Active Directory Device. The authentication is checked against Unix, SecureID, LDAP / Active Directory or any other third party mechanism (3PA).

OSGD also allows you to print from applications and is also capable of connecting the file system of the workstation with the application server in the data center. This method, however, defeats the separation of security zones and therefore needs to be examined closely from a technical security perspective.
Several OSGD servers can be combined to an array (Intelligent Array Routing, IAR). This ensures, besides a scaling of up to several thousand users, a redundancy and the optimization of communication.
