 By
creating a thin client to run on Microsoft® Windows® desktops,
ClarioNET helps you deliver a thin client identical to the
applications the end user is used to. There’s no need to
move the end user a platform they don't want or use html
to approximate a real program, and ClarioNET takes full
advantage of the resources on the Windows platform to keep
communications with the server to a bare minimum—possibly
the lowest bandwidth remote client yet for graphical business
applications.
The ClarioNET solution divides a Clarion
application into a user interface layer and application
layer. An end user downloads a small "client" program that
is about 500KB, good for multiple sessions and/or applications.
The "client" connects to a server in a series of compressed,
encrypted transactions. The server sends instructions to
the client to create a window and controls. Because the
client is itself a windows application, it appears exactly
like any other application, except for a small "LED" indicator
on the caption bar that indicates when the client is sending
or receiving information to or from the server. This solves
the dilemma facing many companies attempting to deploy thin
client solutions who quickly learn users are reluctant to
trade their PCs for graphics terminals and thin client operating
systems.
The client supports all functions of
a typical business application, including printing reports
to the local printer. The end user has the ability to run
their applications from any machine connected to the web
(or the corporate Intranet). IT professionals and ASP providers
gain security and control of the data, reducing the risk
of a catastrophic loss by theft, accident, hardware failures,
or security breaches.
Communications between client and server
are economical. Typically, when a new window is displayed,
the client and server exchange about 3,000 bytes of data.
Thereafter, only update instructions are exchanged and involve
less than a few hundred bytes. No constant communications
stream is maintained with the server, keeping overall bandwidth
requirements down, and server activity to a minimum.
In tests on a Windows 2000® server with
twenty clients opening windows onto database tables, CPU
activity on the server was kept below 15%, and memory usage
was kept below 25% on a 512MB system. Only HTTP protocol
is used, ensuring compatibility with most firewalls.
- Minimal client requirements: Microsoft Windows (Windows
95, 98, Windows NT, Windows ME, Windows 2000,
Windows XP), as small
as a 550KB .EXE footprint, about 6 meg RAM usage and
an IP connection.
- Compressed encrypted communications, ultra low bandwidth
requirement from client to server.
128 bit data encryption.
- Structured and formatted report printing to the
clients’ local printer utilizing native Windows printing
capability.
- Native windows user interface deployment to clients.
- Allows for file transfers between client and server,
though normally the database remains server-side.
- Allows for personal configuration (.INI) files on
the client, storing end user preferences.
- Full support for backgrounds, icons, images, fonts,
and other typical window or control attributes.
- Is capable of using client side procedures for extended
functionality.
- Efficient server "query" mode enable a who new area
of functionality.
- Automatic Windows Help "HLP" support.
- Uses only HTTP port 80 or 8080; hence, minimal if
any impact on firewall configuration.
- Low cost implementation
- Tight integration with the ClarioNET Server Deployment
Manager.
