  • Citrix MetaFrame Presentation Server is a technology that can allow remote users to connect to applications that are actually installed on a remote computer.
  • This is useful for users who are unable to run various Windows programs on their PCs, or people who use many PCs and need to use a common instance of a program across all their computers.
  • Programs are run on thin client server and the user interface is displayed on the user’s machine. This system is called ‘Thin Client’ because the client PC does not need to have the resources needed to run the full program, only the user interface, so can be a lower specification (thin) PC.
  • These Presentation Servers let users connect any client device to any application running on the presentation server (terminal server).
  • Citrix clients are available for Windows, Mac, various flavors of UNIX, and even EPOC handheld devices.
  • There is a UNIX version of Presentation Server so you can run UNIX and Java applications on a terminal server while accessing them from Windows clients.

Internals

  • Citrix Presentation Server uses ICA (Independent Computing Architecture) protocol, for transmitting keystrokes, mouse movements, and screen updates between thin clients and the presentation server
  • Users can use various connections including dial-up and ISDN connections to access the applications. Figure shows the various connection types ICA can support
  • Citrix ICA has the ability to separate application logic from the user interface. On the client, users see and work with the application’s interface, but 100 percent of the application executes on the server.
  • ICA is the Citrix counterpart of Microsoft’s Remote Desktop Protocol (RDP). Table compares both of these protocols

  • Citrix clients do not actively use their own resources to access such infrastructures, rather, just to view the remote session over an optimised protocol.
  • As such, the Citrix Metaframe servers perform the basic I/O, memory management and redirection services on behalf of a number of client sessions. In order to achieve this, the Citrix servers illustrate a linear increase of memory resources according to the number of clients connecting to sessions
