ICA vs RDP

RDP works only under TCP/IP, while ICA works on many protocols.

ICA also has several features that RDP just doesn't support yet. ICA enables application publishing -- where the application is on one server but is available across the cluster -- session shadowing, anonymous users, audio support, and drive, printer and port mapping ICA is also built into Internet Explorer and is available as a free plug-in for Netscape. RDP doesn't permit applications to run in a browser

ICA is a protocol developed by Citrix.
RDP is developed by Microsoft.

Each performs the same virtualization channels to the end user clients.

ICA worksat low bandwidth but RDP doesn't work at low bandwidth

Encryption is possible in ICA,it is not present in RDP
Keybord and mouse inputs will be present in ICA
Session Reliability will be there in ICA,it is not in the RDP

1. RDP works only under TCP/IP, while ICA works on many protocols.
2. RDP doesn't permit applications to run in a browser, while works for ICA
3. Session Reliability will be there in ICA,it is not in the RDP
4. Encryption is possible in ICA,it is not present in RDP
5. ICA also supports non windows like DOS, UNIX, MACOS, mobiles

ICA vs RDP,

ICA- Independent Computing Architecture (Citrix Protocol) 1494
RDP- Remort Desktop Protocol (Microsoft protocol) 3389

RDP supprots only desktop or server console.
ICA supprots published applicaion, Desktop, Content, and it will work under 10kb- 20kb

ICA is a citrix communication protocol used to exchange data in a server
environment. RDP is a windows terminal service protocol. ICA works on even
low bandwidth connection at a minimum of 14.4kbps. ICA is much faster than
RDP. RDP works only with TCP/IP protocol but ICA works with TCP/IP,IPX/
SPX ,Netbeui etc.
