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 .
