Interoperability: A Perspective
Stan Schneider
Real-Time Innovations, Inc. CEO & IIC Steering Committee
Levels of Interoperability
• What level?
• Mandate?
• Guidelines?
• How?
• When?
http://en.wikipedia.org/wiki/Conceptual_interoperability
RTI’s Experience
• ~800 Designs– Healthcare– Transportation– Communications– Energy– Industrial– Defense
• 15+ Standards & Consortia Efforts
Interoperable Navy Open Architecture
• Next-generation of – Lockheed Aegis– Raytheon DDG 1000– Raytheon SSDS– LCS (Lockheed and GDAIS)– Raytheon LPD-17– Many more, US and allies
• Highly distributed systems include radar, weapons, displays, controls
• Standards-based, high-performance middleware breaks vendor lock-in, drives interoperability ,and future-proofs the architectural design

Facilitate Plug-n-Play Across Vendors
• Audi hardware-in-the-loop simulation feeds realistic data to components for testing
• The system offers plug-n-playbetween simulation vendor solutions
• RTI middleware enables a modular test environment that scales to work with hundreds of devices
Integrate New and Old
• The VW Driver Assistance and Integrated Safety system combines radars, laser range finders, and video to assist safe operation
• The V-Charge program demoed a self-driving vehicle in 2014
• The system integrates with existing CANbus through VW Cargate™ ECU
• RTI enables advanced reactive systems in transportation

"GE Healthcare chose the DDS standard because it can handle many classes of intelligent machines.
RTI Connext DDS satisfies the demanding requirements of our devices and supports standardization on a single communications platform across product lines."
-- J Gustavo Perez, General Manager for
MI&CT Engineering
Improve Safety by Connecting Devices
• Hospital error is the 6th
leading cause of preventable death
• The Integrated Clinical Environment (ICE) standard specifies interoperability for medical devices
• RTI Connext DDS ties together many classes of devices from many vendors
“RTI Connext DDS met all our needs – whether
we’re handling 12 patients, or 200.”
-- DocBox Founder, Tracy Rausch
The Industrial Internet Consortium
• Goal: Interoperability for the IIoT• 140+ companies!• RTI role
– Steering committee, data management (lead), framework, security, use case (lead), marketing
– Lead or co-lead 3 testbed teams

• OMG: world’s largest systems software standards org
– UML, DDS, Industrial Internet Consortium
• DDS: open & cross-vendor
– Open Standard & Open Source
– 12 implementations

Interoperability of the Word “Interoperability”
“Interoperability” is meaningless without “between”
Interoperability Between Applications
• Proximity
• Platform
• Language
• Physical network
• Transport protocol
• Network topology

Interoperability Between Security Entities
• Per-Topic Security– Control r,w access for each
function– Enforce each dataflow
• Complete Protection– Discovery authentication– Data-centric access control– Cryptography– Tagging & logging– Non-repudiation– Secure multicast– 100% standards compliant
• No code changes!• Plugin architecture for
advanced uses
• Topic Security model:– PMU: State(w)– CBM: State(r); Alarms(w)– Control: State(r), SetPoint(w)– Operator: *(r), Setpoint(w)
