Durai,
ICA - protocol used by Citrix for windows terminal servers
RDP - protocol used by Microsoft for windows terminal servers
RDP is pretty close to ICA, Microsoft buy this technology from Citrix many years ago.
(See http://www.brianmadden.com/content/content.asp?id=98 as well)
RDP and ICA have Linux/Unix clients (http://www.rdesktop.org/)
RFB - RFB (remote framebuffer) is a simple protocol for remote access to graphical user
interfaces. Because it works at the framebuffer level it is applicable to all windowing systems and applications, including X11, Windows and Macintosh. RFB is the prototol used in VNC (Virtual Network Computing).

And X - used in Linux/Unix systems.
It is hard to compare RFB and X to ICA/RDP - it is just different.

Hi Vel,

ICA Protocol:

The ICA protocol is used in both WinFrame and MetaFrame environments, and under the new product versions (1.8), WinFrame and MetaFrame have comparable features.
