DDS
RTPS middleware for Real-Time Distributed Industrial Vision Systems
Designing and constructing Real-Time Distributed Industrial Vision Systems (RT-DIVS) from scratch is very complicated task. RT-DIVS has Conflicting requirements such as reasonable development cost, ease of use, reusable code and high performance. The success key in building such systems is to recognize the need for middleware software. Middleware plays a major role in developing distributed systems efficiently.
Dr. Dobb's New Series on The Data Distribution Service for Real-Time Systems
Dr. Dobb's has started a new series on The Data Distribution Service for Real-Time Systems.
Part 1 of the series focuses on what DDS is, why it represents an important technology you should learn about, and how it is being used today. Part 1 of the series is available at: http://www.drdobbs.com/architect/222900238
The series is authored by Angelo Corsaro, PrismTech OpenSplice DDS CTO and co-chair of the OMG Data Distribution Service (DDS) Special Interest Group.
OMG's annual Real-time, Embedded and Enterprise-Scale Time-Critical Systems workshop
OMG's annual Real-time, Embedded and Enterprise-Scale Time-Critical Systems, Washington DC area, 24th - 26th May 2010. Possibly the leading annual gathering of DDS users and implementers. More details: http://www.omg.org/news/meetings/realtime2010/index.htm
Submission deadline for OMG Real-time, Embedded and Enterprise-Scale Time-Critical Systems Workshop
Monday 1st February 2010 is the submission deadline for the OMG Real-time, Embedded and Enterprise-Scale Time-Critical Systems Workshop. The goal of the workshop is to identify the state of the art and disseminate current best practice in real-time and embedded distributed computing, for the benefit of standards users, researchers and implementers. For more details of the workshop, see the Call for Presentations: http://www.omg.org/news/meetings/realtime2010/index.htm DDS users are particularly encouraged to submit; this workshop is one of the major annual gatherings of DDS users and implementers.

Introduction to CoreDX DDS
Hello!
Thank you for visiting our forum section on the OMG DDS portal. Let us take a minute to provide you with some background on our company and CoreDX DDS product.
Twin Oaks Computing has leveraged 30 years of experience developing and supporting large defense systems to develop CoreDX DDS, the most feature rich small-footprint DDS implementation available. Compliant with the OMG Data Distribution Service Standard and with proven interoperability, CoreDX DDS is an essential component for effective open system architectures.
Are there Open Source implementation of DDS?
Yes! To date there are two Open Source implementation of DDS, OpenSplice DDS and OpenDDS.
DDS Interoperability Demo: RTI, Prismtech, TwinOaks
Three vendors: RTI, PrismTech, and TwinOaks Computing performed a live interoperability demo between their respective products.
The demo showcased 7 scenarios:
- Basic interoperability
- QoS Matching
- Quality of Service: DURABILITY
- Time Based Filters
- Quality of Service: RELIABILITY
- Intermittent Connectivity
- Multiple Topics, Keys & Content Filters
And demonstrated interoperability for:
Towards a Safety Critical profile for DDS
The use of DDS has gained widespread adoption in command-and-control applications due to its support of the publish-subscribe communications model typically found in such systems. DDS has been field-proven in extremely complex systems consisting of thousands of endpoints with high data rates and stringent latency budgets.
Using SELinux to secure DDS applications: Proper configurations and Lessons Learned
hen DDS is used in complex distributed systems-of-systems, numerous security concerns may arise. These include ensuring availability of the system, resistance of the system to un-trusted network traffic, and confidentiality of sensitive data. As systems are increasingly interconnected, it is crucial that security concerns be considered early in the design process.
Leveraging DDS-RTPS Wire Interoperability Protocol: Towards a canonical tool-set for run-time interaction with the Global Data Space
This presentation exposes recent research in DDS Global-Data Space tools that leverage standard display models such as Microsoft Excel’s; it also explores the different categories of DDS run-time tools drawing requirements and specific examples from COTS tools commonly used to interact with data.
