OMG Members Demonstrate that Multi-Vendor Data Distribution Service (DDS) Wire-Protocol Interoperability is a Reality
Public Demonstration at OMG Technical Meeting Illustrates
Seamless Communication between different DDS Implementations

Needham, MA - March 25, 2009 - OMG™ member organizations today demonstrated wire-protocol interoperability between different implementations of its Data Distribution Service for Real-Time Systems standard (DDS), during an OMG technical meeting. The demonstration showed simulated sensor data being exchanged by applications running on three independent DDS implementations: OpenSplice DDS from PrismTech, RTI Data Distribution Service from Real-Time Innovations and CoreDX from Twin Oaks Computing.

DDS middleware allows distributed applications to communicate with each other by exchanging and sharing real-time data. The advent of cross-vendor interoperability significantly eases the integration of applications that natively use different DDS solutions by providing "plug-and-play" interworking, eliminating the need to bridge between implementations.

Multi-vendor wire-protocol interoperability extends the loose coupling already afforded by DDS, providing adopters with maximum flexibility and vendor independence. DDS applications could already communicate even if they were written in different programming languages or running on different operating systems or processor architectures. Because DDS defines standard programming interfaces, application software was also portable across different DDS implementations. Now, wire-protocol interoperability makes direct communication possible between applications built using different implementations of the DDS standard.

"This demonstration marks a significant milestone for the DDS standard," commented Dr. Richard Soley, Chairman and Chief Executive Officer of the OMG. "In the four years since its standardization, DDS has been embraced by hundreds of programs and projects to address their real-time data distribution and application integration requirements. The arrival of multi-vendor wire-protocol interoperability will unleash an additional wave of adoption by further reducing integration costs and increasing vendor independence."

"This demonstration showcases the quality and value of the OMG process and the DDS and RTPS standards. Today we showed that a vendor without involvement in the RTPS standardization process could develop an implementation using only the published standards and fully interoperate with the other DDS vendors. Our latest version of CoreDX, with support for the RTPS wire protocol, is an attractive solution for system developers looking for a high-performance, small footprint, publish-subscribe middleware component with proven interoperability," commented Nina Tucker, Vice President, Twin Oaks Computing, Inc.

"RTI's customers are building systems that will be deployed for decades. DDS is their integration technology of choice not just because of its technical advantages. Most critical to infrastructure projects is that it significantly reduces both cost and risk. Multi-vendor interoperability reinforces this benefit while extending the value of DDS as a truly open architecture, vendor independent and future-proof standard," said David Barnett, vice president, marketing at Real-time Innovations (RTI).

"Today we've proved that DDS not only is the best standard for real-time data distribution, but it is also the only standard providing on-the-wire interoperability across multiple vendors without introducing performance penalties or single point of failures," commented Dr. Angelo Corsaro, Product Strategy and Marketing Manager, PrismTech. "Furthermore, thanks to OpenSplice DDS, the OMG DDS is the only data distribution standard for which interoperable, high-performance, high-quality, and widely deployed Open Source implementations exits. This is a very powerful combination, bringing high strategic value to DDS users, that will further propel its success in traditional and new markets."

About DDS
DDS, thank to its loose coupling, dramatically reduces the software lifecycle costs associated with developing, maintaining, integrating and scaling distributed real-time applications. Unlike other messaging and integration standards such as SOAP and Java Message Service (JMS), DDS was designed specifically to meet the performance and Quality of Service (QoS) requirements of real-time and embedded systems. As a result, it has been widely adopted for time-critical and mission-critical applications such as tactical defense systems; air, rail and roadway traffic management; industrial control and Supervisory Control and Data Acquisition (SCADA); and financial market data distribution and automated trading.

The DDS application programming interface was adopted by the OMG in December 2004. The version of the DDS Real-Time Publish-Subscribe (RTPS) wire interoperability protocol demonstrated today was adopted in June 2008. It extends a version of RTPS that was adopted as an International Electrotechnical Commission standard in 2004 (IEC 61158).
