It has been said that knowledge (information) is power, however, it is the distribution and consumption of information that creates value in the market place.

Standards based communications provides savings in the world of complex system integration. At the same time there are lingering perceptions that Standards can reduce competitive advantage.

The communication network providing real-time image sharing between the planning office and the warehouse for supply chain management is presented in this paper. Middleware plays a major role in developing distributed system efficiently for communication between image capturing devices (Vision Node) and image processing node as well as the distributed nodes. The image distribution over the network in real-time manner is useful to numerous logistic applications, such as quality control of pick-and-pack service, planning of cargo and pallet loading, and vehicles tracking.

Seaware is a publish-subscribe middleware used in multi-vehicle networked systems composed of autonomous and semi-autonomous vehicles and systems. Seaware provides a high level interface to network communications and may be deployed with a combination of heterogeneous components within a dynamic network.

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.

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:

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.

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.

Twin Oaks Computing, Real-Time Innovations, and PrismTech participated in a multi-vendor DDS interoperability demonstration during the March 2009 OMG Technical Meeting in Arlington, VA, USA. In this presentation, we will describe the events leading up to the demonstration and discuss how we were able to achieve success. We will cover challenges faced, lessons learned, and touch on related future work.
