IIC Connectivity Framework Document
• Provides a comprehensive treatment of IIoT connectivity
• A new connectivity reference architecture to provide for
secure interoperability between applications in an IIoT
system
• A new connectivity “stack” model focused on syntactic
interoperability for the IIoT
• Detailed analysis of key IIoT connectivity technologies
against this new stack model
– DDS, OPC UA, HTTP, OneM2M, MQTT, CoAP
• Download it here: http://www.iiconsortium.org/IICF.htm
– V1.0 released Feb 28, 2017

• Reliability: Severe consequences if
offline for 5ms (or 5 min)
• Real-time: measure in ms or µs
• Interface scale: 10+
applications/teams
• Dataflow complexity: data has
many destinations
• Architecture: Next generation IIoT
Deployed in 1000s of Systems Industrial IoT Systems
Industries: Energy, Industrial Control, Transportation, Healthcare, Defense

DDS: Open IIoT Standard
• Data Distribution Service (DDS) is an open
industry standard for data-centric connectivity
• From OMG, the world’s largest systems
software standards organization
– UML, DDS
– Industrial Internet Consortium (IIC)
• DDS is Open & Multi-Vendor
– Open Standard & Open Source
– 12 implementations
Interoperability
between source written
for different vendors
Interoperability between
applications running on different
implementations

Security Boundaries
• System Boundary
• Network Transport
– Media access (layer 2)
– Network (layer 3) security
– Session/Endpoint (layer 4/5) security
• Data & Information flows

.
DDS: Data-Centric, Fine-Grained Security
• Per-Data-Topic Security
– Control r,w access for each function
– Ensures proper dataflow operation
• Complete Protection
– Discovery authentication
– Data-centric access control
– Cryptography
– Tagging & logging
– Non-repudiation
– Secure multicast
– 100% standards compliant

System Aspect Example User Approach Target
Standard
Software
Integration and
Autonomy
You are a software architect. You are building
a system or product line, and you control the
architecture. You critically need to integrate
components written by different programmers
or even entire teams.
A data centric approach will define the
interfaces, capture the dataflow, enable
module evolution, and enforce
interoperation between teams. This
approach also eases redundancy, fast
complex data flow, and selective data
filtering.
DDS
Device
Interchangeability
You are a device manufacturer, with the goal
of making devices that will sell into many
applications. The device offers services, such
as configure, start, stop, etc. You have no idea
how the device will eventually be used. Your
users are likely not software experts; they just
want to add or integrate the device into a
workcell.
A device-centric approach will allow the
device users to write generic software that
will interoperate with competitor’s devices.
