To provide DDS with a deterministic network infrastructure that can guarantee time-critical behavior, the OMG DDS Extensions for Time Sensitive Networking (DDS-TSN) defines a set of mechanisms that allow and simplify the deployment of DDS applications over a TSN-enabled network infrastructure. Mapping DDS streams to underlying TSN Streams, system designers can rely on a deterministic data distribution behavior from end to end.

The Object Management Group (OMG) IDL to C# Language Mapping specification (IDL4-CSHARP) defines a mapping of the OMG Interface Definition Language (IDL) to the C# programming language.

The Object Management Group (OMG) OPC UA/DDS Gateway specification (DDS-OPCUA) defines vendor-independent, configurable gateway that enables interoperability and information exchange between systems that use DDS and systems that use OPC UA.

The Object Management Group (OMG) DDS Consolidated JSON Syntax specification (DDS-JSON) defines a consolidated JSON syntax to represent DDS resources and data. That is, syntax to represent the DDS Type System, DDS QoS Policies, DDS Entities and Applications, and DDS Data Samples using JSON.

The Object Management Group (OMG) DDS Consolidated XML Syntax specification (DDS-XML) defines a standard set of schema files to represent OMG DDS resources and data using XML.

Section 7.4.3 of the AUTOSAR Adaptive Specification of CommunicationManagement defines a DDS Network Binding for ara::com, which enables AUTOSAR Adaptive applications to use DDS as the underlying communication framework.

Avionics Sensor Health Assessment is a sub-discipline of Integrated Vehicle Health Management (IVHM), which relates to the collection of sensor data, distributing it to diagnostics/prognostics algorithms, detecting run-time anomalies, and scheduling maintenance procedures. Real-time availability of the sensor health diagnostics for aircraft (manned or unmanned) subsystems allows pilots and operators to improve operational decisions. Therefore, avionics sensor health assessments are used… Mostrar más

Avionics Sensor Health Assessment is a sub-discipline of Integrated Vehicle Health Management (IVHM), which relates to the collection of sensor data, distributing it to diagnostics/prognostics algorithms, detecting run-time anomalies, and scheduling maintenance procedures. Real-time availability of the sensor health diagnostics for aircraft (manned or unmanned) subsystems allows pilots and operators to improve operational decisions. Therefore, avionics sensor health assessments are used extensively in the mil-aero domain. Mostrar menos

As centralized computing models are being superseded by more distributed computer environments, supervising application, system and network health has become a crucial task in network management. Currently, there are plenty of systems providing a partial solution to this problem (e.g. intrusion detection systems (IDS) and system monitoring tools), but each separately cannot provide the complete view required to understand and react quickly.

As centralized computing models are being superseded by more distributed computer environments, supervising application, system and network health has become a crucial task in network management. Currently, there are plenty of systems providing a partial solution to this problem (e.g. intrusion detection systems (IDS) and system monitoring tools), but each separately cannot provide the complete view required to understand and react quickly.

In this context we propose Cave Canem, a framework for the development of a "complete" operational picture for the combination of multiple kinds of information (e.g. performance, system alerts, intrusion detection), remaining open so that new sensors and applications can be mixed in. This open approach, separates the Information Model from the Information Distribution mechanisms, using the OMG Data Distribution Service (DDS) standard as the fundamental information-sharing model.

Our framework exploits the benefits of the data-centric publish-subscribe (DCPS) paradigm provided by the DDS middleware, which eases the deployment and maintainability of large monitoring scenarios. It also takes advantage of some of the DDS features, such as content filtering and QoS settings (reliability, transport priorities, etc.) which ensure that the entire system status can be efficiently distributed according to the subscriber interests.
In the presentation we will purpose a motivating example for highlighting our design goals, describe the architecture and the implementation details of our solution, and demonstrate a validated prototype. Mostrar menos

Performance measurement is crucial in the development of efficient software. It becomes even more important in applications designed to run in embedded and real-time systems, where a fast response or high performance is required. This article describes the development of a deterministic application for performance measurement, which has been successfully used in a Computer Engineering Processor Design and Configuration Assessment course at Higher Technical School from the University of Córdoba.
