A general statement of the typical applications that rely on this connectivity technology and the reason for using the connectivity technology.
DDS is already proven in mission-critical systems in industries ranging from smart transportation to healthcare to smart energy, and also aerospace & defense. Reasons for using DDS include:
• Ease of Integration: The data-centric approach used by DDS allows the definition of common and extensible data models for seamless Information Technology( IT) / Operational Technology( OT) interoperability. Its loose and anonymous datasharing abstraction completely hides connectivity and topology details from applications.
• Performance Efficiency and Scalability: DDS implementations can achieve point-topoint latencies that are as low as 30 µ sec. and throughput of several million messages per second. It uses a very efficient wire protocol, content- and timebased filtering. When properly architected, DDS-based systems can achieve nearlinear scalability.
• Advanced Security: The OMG DDS Security Specification defines a comprehensive Security Model and Service Plugin Interface( SPI) architecture for compliant DDS implementations. DDS provides standardized authentication, encryption, access control and logging capabilities to enable secure data connectivity end-to-end in an IoT system.
• QoS-Enabled: A rich set of QoS policies allows DDS to control of all aspects of data distribution, such as timeliness, traffic prioritization, reliability and resource usage.
• Scalable Discovery: For large-scale dynamic systems, DDS offers automatic discovery that provides plug-and-play functionality to simplify system integration and orchestration.
• Applicability: DDS can transparently address peer-to-peer, device-to-device, device-to-cloud and cloud-to-cloud communication. Implementations are available for embedded, mobile, web, enterprise and cloud applications.
• Future Proof: The OMG DDS middleware specification enables end-to-end vendor interoperability and eases IoT system development and integration through fully open, future-proof APIs with no vendor lock in.
What function or where in the system this technology is typically used?
• Data plane( Data Collection; Data Distribution; Data Streaming)
• Control plane( Commands & Status; Orchestration)
• Monitoring plane( Remote Monitoring & Diagnostics)
• Management plane( Events, Analytics & Alarms; User Interfaces) Can one monitor, manage, and dynamically replace elements of the connectivity function?
Yes, one can monitor and manage a data-space simply by adding an application to participate in data-space. One can also simply replace a participant in the data space by another.
