Sun licenses Citrix's ICA protocol for JavaStation software environment.

NEW YORK--(BUSINESS WIRE)--Oct. 29, 1996--

Citrix ICA Client Will Enable Java Users to Run 32-Bit Windows

Applications

Citrix Systems, Inc. (NASDAQ:CTXS) and Sun Microsystems, Inc. today announced they have reached a definitive licensing agreement for the ICA distributed Windows protocol. Under the agreement, Citrix will port its ICA client to the Java virtual machine environment. Citrix will license the resulting ICA client module to Sun, which will embed the ICA client for Java into the JavaStation software environment. As a result, full-function 32-bit Windows applications will run in a variety of Java operating environments and devices.

The first such device anticipated from Sun is the JavaStation network computer. According to the contract, future JavaStations will include the ICA client for Java. This will enable Java users to access robust Windows applications, in conjunction with Citrix's WinFrame multi-user application server software.

"We are committed to partnering with industry-leading software and hardware companies to extend the reach of Windows applications into new markets through the licensing of ICA technology," said Edward Iacobucci, Citrix chairman and chief technical officer. "Together, Citrix and Sun Microsystems intend to provide businesses with a network-centric computing solution that quickly and easily extends access to line-of-business applications, while lowering the cost of application deployment and management."

"Like Citrix, Sun Microsystems is committed to network-centric products that provide users with an efficient, cost-effective solution for expanding the availability of business-critical applications within and beyond the walls of an organization," said Steve Tirado, director of marketing of Sun's Java Systems Group. "The ICA client for Java, bundled with the JavaStation software environment, gives our users the freedom to access a broader range of applications to most appropriately fit the task at hand."

Citrix's ICA protocol is being broadly adopted by industry leading vendors including Microsoft Corporation, Wyse Technology, Boundless Technologies, Tektronix, Insignia Solutions, NCD, Telxon Corporation and Plexcom for inclusion in new and future hardware and software products that extend the reach of Windows applications into new markets.

Citrix's ICA licensing strategy enables OEMs to deliver the benefits of Windows-based, network-centric computing to users of low-cost terminals, information appliances and network computers; users of non-Windows platforms, including DOS, UNIX and Macintosh; users of rapidly emerging small form factor PDAs and other wireless devices; as well as users over the Internet or Intranet.

ICA is a general-purpose presentation services protocol for Microsoft Windows, which allows an application's user interface to execute with minimal resource consumption on a client device, while the application logic executes on ICA-based servers, such as the Citrix WinFrame family of multi-user application servers.
