The diagram above describes the preliminary deployment for IFESS.
The IFESS system will be based on a client-server architecture, and will therefore require a central server (located on the aircraft), as well as individual client terminals. The server will process client requests and return the requested data.Internet based data will be routed from the ground through satellite hardware installed on the aircraft. A firewall independent of the IFESS system will be implemented on the central server for security. A tape drive will be availble for periodic data archiving.
Users will interface with IFESS through a touch screen and a keyboard. Separate consoles will be required for passengers, flight attendants and pilots. Administrators can log onto any console.
