RSVP Today for Munich Connext Conference 2017!

The World's Largest Gathering of Power DDS Users

London Connext Conference 2014 and 2015 events brought power DDS users together from a wide range of industries to share experiences, applications and expertise.

Future Proof IoT: Composable Semantics, Security, QoS and Reliability

IETF impressively defined internet interoperation across 30 years of unforeseeable syntax API. IOT needs similar future proof, but for connected things' composable semantics, security, reliability and Quality of Service (QoS). This paper overviews these with simplifying tradeoffs from a bottom up approach using Data Distribution Service (DDS). Then high level semantic additions to DDS are suggested for semantics that are backward compatible, while maintaining the security, reliability and QoS of DDS.

Distributed Simulation Using DDS and Cloud Computing

NASA Langley Research Center identified a need for a distributed simulation architecture that enables collaboration of live, virtual, and constructive nodes across its local area network with extensibility to other NASA Centers and external partners. One architecture that was prototyped and evaluated employed Data Distribution Service (DDS) middleware and the GovCloud cloud computing service. The nodes used DDS to exchange data.

An investigation into some security issues in the DDS messaging protocol

The convergence of Operational Technology and Information Technology is driving integration of the Internet of Things and Industrial Control Systems to form the Industrial Internet of Things. Due to the influence of Information Technology, security has become a high priority particularly when implementations expand into critical infrastructure.

Applying MBSE to the Industrial IoT: Using SysML with Connext DDS and Simulink

The benefits of Model-Based Systems Engineering (MBSE) and SysML are well established. As a result, users want to apply MBSE to larger and more complex Industrial IoT applications. 

Industrial IoT applications can be very challenging: They are distributed. They deploy components across nodes spanning from small Devices to Edge computers to the Cloud. They often need mathematically-complex software. Moreover, they have strict requirements in terms of performance, robustness, and security. 

Conference or Venue:

See You at the Munich Connext Conference!

As an RTI product developer working out of our Spain Office, my main focus is the design and implementation of our Connext DDS Secure product. With that said, I still interact with customers almost on a daily basis, especially our customers based in EMEA. But most of these interactions take place digitally (e.g., e-mail and phone calls), and through our (btw, fantastic) support and services teams. As such, I don’t usually have the opportunity to meet the customers I work with “behind the scenes” in person.

That’s why I’m excited to be part of this year’s Munich Connext Conference! The Munich Connext Conference is an incredible opportunity to learn first-hand how our customers are applying Connext DDS to solve various technical challenges across the Industrial Internet of Things (IIoT). At previous conferences we’ve also had the opportunity to hear your feedback about our product, and using that feedback to influence future releases. It is also a great opportunity to meet other DDS users and to meet us --RTI developers and architects-- so we can all share our experiences in building real-world IIoT systems.

Need your advice

Hello,

I'm working on master thesis project where I need to apply DDS with existing CPS system for smart buildings. CSP system's source code written with modeling language called ThingML. After compiling program runs as Java application.

Simple version of this CPS receive temperature from one or more thermometers. After that CPS sends signal to turn on/off heater switcher.

So my question is how/where to start?

Python (Connector) Subscriber - Subscribe to Java Example

Hi,

I have been working with the hello_idl example in the rti_workspace->examples->connext_dds->java.

I want to write a subscriber in Python that can listen to the java publisher. But so far I haven't gotten it to work. What do I need to change in the .xml to be able to listen to the java publisher.

Organization:

Novel Design of Collaborative Automation Platform Using Real-Time Data Distribution Service Middleware for An Optimum Process Control Environment

Refining and petrochemical processing facilities utilize various process control applications to raise productivity and enhance plant operation. Client–server communication model is used for integrating these highly interacting applications across multiple network layers utilized in distributed control systems.
