Citrix

Citrix is a proprietary server, protocol and client that runs on the Microsoft Windows platform to serve Windows desktop terminal sessions to Windows OS client sessions. On a POSIX platform like Linux & BSD this is very much like how X11 client and servers (XFree86 & Xorg) connect using XDMCP.

Other comparable products would include NX from NoMachine the open source FreeNX project and Microsoft RDP.

Companies that use Citrix justify the high cost by the unique features that set Citrix apart from other terminal systems.

Features

• Extremely low bandwidth requirements (as slow as dialup)
