6.1. TYPICAL APPLICATIONS

The

STPC

Atlas

well

suited

for

many

applications.

Some

the

possible

implementations are described below.

6.1.1. THIN CLIENT

A Thin-Client is a terminal running ICATM (Citrix)

or RDP

TM (Microsoft) protocol. The display is

computed by the server and sent in a compressed

way to the terminal for display. The same

streaming approach is used for sending the

keyboard/mouse/USB data to the server.

These protocols have room for dedicated data

channels in case the terminal is not ’thin’ and can

execute

locally

some

applications,

hence

optimizing the bandwidth usage. For example, if a

terminal

has

browsing

MPEG

decoding

capability, the server will provide internet source

files or MPEG streaming.

The same hardware can run X-terminal protocol

and can be reconfigured by the server when

booting on the network by uploading a different

OS and application.
