DDS: Enabling Smarter Distribution Grids
David Barnett | [email protected] | @rtidavidDecember 12, 2013
Centralized Monitoring and Control
• Constrains volume of real time data that can ‑be analyzed– Capacity of network links– Servers
• Poor latency• Single point of failure
• Doesn’t scale (cost, tech)– More sensors– Distributed generation
• Limits efficiency, responsiveness– Demand response– Fault isolation, correction– Predictive maintenance

Other Impediments to Modernization
• Protocols galore– SCADA, DNP3, IEC 61850, C37.118, proprietary– Expensive app development and integration
• Security

Data Distribution Service (DDS)
• Software “data bus”• Distributes data where its needed, when its needed• Completely decentralized

Simple Yet Powerful Paradigm
• Applications write (publish) and read (subscribe) data
• Like a database but for data in motion
• DDS automatically routes data between publishers and subscribers
• Data: raw, processed or commands• Decoupling: apps require no
awareness of source or destination• Normalized data model• Extensive Quality of Service

Decentralized Architecture
• Peer-to-peer communication– No centralized software, servers or message brokers
• Minimizes software infrastructure that has to be deployed and managed
• No single point of failure or choke point• Very low latency, high throughput, scalable

Broad Interoperability for Heterogeneous Systems
• Programming languages and environments– C, C++, C#/.NET, Java, Ada– REST/HTTP– LabVIEW, MATLAB, Simulink, UML
• Operating systems– Windows, Linux, Unix, Mac OS– Embedded, real time, partitioned– Mobile
• Processor families– x86, ARM, PowerPC– 32- and 64-bit
• Transport types– Shared memory– LAN (incl. multicast)– WAN– Wireless– Low bandwidth

Automatic Discovery EnablesAutonomous Systems• Plug and play, self forming, self healing• No system administration required• Automatic failover• Apps and devices are dynamically upgradeable– Never have to restart an entire system
• Apps can be notified when data sources/sinks join/leave (presence)

Minimizes and Optimizes Bandwidth
• Fine grained subscription control: by time and content• Only subscribed data is sent within or between subnets• Most metadata exchanged only at discovery time• Efficient binary encoding• Optional data compression• Connectionless: tolerant of intermittent networks
