Programs
- XPe Client is a client/server-based computing platform. On this platform, the client accesses the
server each time it needs a program and it only receives the user interface screens from the server.
Hence, various programs, such as ICA, RDP, and VNC, which are installed on a XPe Client, are
used to help the client access the server and perform user tasks.
Citrix Program Neighborhood
Independent Computing Architecture (ICA) allows you to use applications on the server through a wide
range of platforms and networks regardless of their basis.
The ICA MetaFrame Server separates the application’s internal logic from the user interface. Due to this
separation, users only work with the user interface on the client. The actual application is 100% run on the
server. In addition, running an application through ICA only uses approximately 10% bandwidth compared
to running it locally. By using this feature of ICA, users can do more work on the client than working locally.
The core technologies of ICA are as follows:
Thin Resource
- Low system requirements needed for running ICA; a computer equipped with an Intel 286
processor and 640K RAM is sufficient. This means ICA can be run on any computer that exists at
present.
Thin Wire
- The default bandwidth required by ICA protocol is 20 kbps, on average. Therefore, even with a
Dial-Up or ISDN connection, a consistent performance is maintained. Any program, however large
it is, can be run stably at a low bandwidth.
Universal Application Client
- The Citrix ICA protocol separates the user interface from the application. While an application is
running on the WinFrame multi-user application server, its user interface is running on the thin
client software of WinFrame. Hence, in any environment, it is possible to run applications fast.
Platform Independent
- ICA is inherently being operated regardless of the operating system platform. Because the clients
for UNIX, OS/2, Macintosh, and Non-DOS are already on the market, you can run Windows
applications on these operating systems.
