OMG DDS Interoperability Demo 2010

Interoperability demonstration between 6 different products that implement the OMG DDS Interoperability Wire Protocol (DDS-RTPS). The demonstration took place at the December 2010 OMG technical meeting in Santa Clara, California. The following companies demonstrated interoperability between their products: RTI (Connext DDS). TwinOaks Computing (CoreDX), PrismTech (OpenSpliceDDS), Gallium Visual Systems/Kongsberg (Compass DDS).

A content-aware bridging service for publish/subscribe environments

Abstract: The OMG DDS (Data Distribution Service) standard specifies a middleware for distributing real-time data using a publish-subscribe data-centric approach. Until now, DDS systems have been restricted to a single and isolated DDS domain, normally deployed within a single multicast-enabled LAN. As systems grow larger, the need to interconnect different DDS domains arises. In this paper, we consider the problem of communicating disjoint data-spaces that may use different schemas to refer to similar information.

Adaptive Architectures for Future Highly Dependable, Real-Time Systems

Many present-day safety-critical or mission-critical military applications are deployed using intrinsically static architectures. Often these applications are real-time systems, where late responses may cause potentially catastrophic results. Static architectures allow system developers to certify with a high degree of confidence that their systems will provide correct functionality during operation, but a more adaptive approach could provide some clear benefits.

Middleware solutions for automation applications - case RTPS

Abstract: This thesis has been written as a part of a research project, whose goal is to define the architecture and communication requirements of next-generation process automation systems. We focus on defining appropriate communication mechanisms for components that communicate with each other using Ethernet.

Evaluation of a Real-Time Distribution Service

Abstract: As control systems become more distributed and they are implemented with smaller hardware and software components, implementing the necessary communication links becomes challenging. There are considerable technical difficulties in guaranteeing upper bounds for latencies in motion or machine control, synchronizing the execution and communication of distributed components, taking corrective action in fault situations and reconfiguring the system.

The Wireless and Multimedia Networking Lab researches both the DDS technology as well as the use of DDS for demanding real-time applications. We have serveral research areas, including:

  • Use of DDS for multimedia applications, specifically audio and video distribution on disadvantaged links.
  • Scalable discovery protocols for DDS.
  • Deployment and configuration of DDS applications.
  • Integration of DDS with other networking technologies.
