DDS Standard

The software connectivity standard providing data connectivity, extreme reliability and a scalable architecture to meet real-time system requirements.

What is DDS?

An Open Standard for Real-Time Applications

The Data Distribution Service (DDS™) standard, managed by the Object Management Group (OMG®), is the software connectivity standard that enables secure real-time information exchange, modular application development and rapid integration in distributed systems. As an original author of the standard, RTI has extensive knowledge and experience with the broad implementation of DDS across industries.

  • DDS is the only open standard for messaging that supports the unique needs of both enterprise and real-time systems.
  • The open interfaces and advanced integration capabilities of DDS slash costs across a system's lifecycle, from initial development and integration through ongoing maintenance and upgrades.
  • RTI Connext software includes the world's leading implementation of the DDS standard.

Open Interfaces

DDS fosters the development of loosely coupled, modular and open architecture systems. By supporting well-defined interfaces between components and subsystems, DDS eradicates stovepipe, closed and proprietary architectures. This eliminates complexity to reduce integration, maintenance and upgrade costs; promotes competition at the subsystem and middleware levels; and eases reuse.


Advanced Integration Capabilities

DDS standardizes powerful messaging semantics that reduce development and integration costs while improving system scalability and robustness.

A Versatile Framework

Across many industries, DDS is the chosen or required connectivity standard for mission- and safety-critical applications. Learn more from these examples:

A Truly Open Standard

  • The OMG is one of the largest computer industry consortiums with hundreds of member organizations including IBM, Microsoft, Oracle, Red Hat and Tibco.
  • OMG manages the Unified Modeling Language (UML) and other popular software standards.
  • Any organization can join and participate in the OMG standardization process.
  • Adopted standards are freely available on the OMG web site.
