Application Server Computing / SBC
There are six major challenges that must be addressed when deciding
how end-users will access their critical business applications:
Application installation and configuration
Prerequisites and requirements of client devices
Bandwidth requirements
Application compatibility Application access from outside the firewall
Security
Application Server Computing Solves all these issues and excels inefficient delivery of applications to the end-user

ICA is optimized for connections as low as 14.4
kbps. Only mouse clicks, keystrokes, and
screen updates travel the network to generate
exceptional performance.
With over two million ports in
use worldwide, Citrix ICA is a
mature, reliable technology
and is a de facto industry
standard for server-based
computing.
Server based computing usingICA provides an ideal solution
for bandwidth-constrained
environments. It offers users
LAN-like application
performance over virtually any
type of connection.
ICA facilitates the old 16 bit &
the latest 32 bit applications to
run on legacy & multi-platform
clients (with great
performance) that normally
would not be able to run them.

Citrix Features
Performance
Persistent Object Caching improves application
performance and reduces network traffic. Graphics are sent
to the client once and stored locally between application
sessions. This allows application splash screens to be
transmitted once, rather than downloaded to the client each
time
Bandwidth is optimized for network connections as low as14.4 Kbps, and delivers bandwidth-independent
performance over LANs, analog or ISDN modems, WANs,
wireless LANs and even the Internet
Security
Eyes-only data transmission; encrypted by default; SSL
relay
Administrators can lockdown specific files, directories,
and system areas as well as the entire system, improving
the security on LAN/WAN, Intranet or Internet.
Anonymous & registered users can access the Citrix Server
from a Web browser
