Blueprint for the Industrial Internet of Things:Architecture

Stan Schneider, RTI CEOIIC Steering Committee

The Future is Intelligent Distributed Machines

What is the Internet of Things?

Industrial Internet of Things (IIoT)Consumer Internet of Things (CIoT)

Cyber-Physical Systems (CPS)

80% of hype

80% of value

World Economic Forum 2015

• The Industrial Internet will transform many industries, including:

– Manufacturing– Oil and gas– Agriculture– Mining– Transportation– Healthcare

• …and dwarf the consumer side

• Collectively, these account for nearly two-thirds of the world economy

The Real Challenge: Span the IIoT

…the “Industrial Internet” <will> start the next Industrial Revolution.

Joe Salvo, GE

The IIoT needs an architecture that spans industries and unites sensor to cloud.

RTI Named Most Influential IIoT Company

RTI’s Experience

• Over $1T of IIoT designs– Healthcare– Transportation– Communications– Energy– Industrial– Defense

• 15+ Standards & Consortia Efforts

– Interoperability– Multi-vendor ecosystems

180+ companies strong

Goal: build and prove a common architecture that spans sensor to cloud, interoperates between vendors, and works across industries

180+ Companies, 22 Countries

The IIRAIndustrial Internet Reference Architecture

The IIRA

• Comprehensive, high level– Strives for breadth rather

than depth– Establishes many key

technical guidelines– Eliminates many approaches– Outlines how things fit

together• Download it here:

http://www.iiconsortium.org/IIRA.htm– Released June 17, 2015– 102 pages

• The Industrial Internet is an internet of things, machines, computers and people, enabling intelligent industrial operations using advanced data analytics for transformational business outcomes.

• It embodies the convergence of the global industrial ecosystem, advanced computing and manufacturing, pervasive sensing and ubiquitous network connectivity.

Document Overview

• Viewpoints– Business– Usage– Functional– Implementation

• Safety• Security, Trust, Privacy

– Endpoint– Communication– Management & Monitoring– Data Distribution & Storage

• Resilience

• Integratability, Interoperability, Composability

• Connectivity• Data Management• Analytics• Intelligent and Resilient

Control• Dynamic Composition &

Automated Interoperability

Connectivity

Fundamental N2 Connectivity Problem

Approach: Limit N

• Choose a single standard for each purpose across the system– Generic Vehicle Architecture (GVA)

• Military ground vehicles

– Industrie 4.0• Manufacturing

• Pro: N=1 eases interoperability• Cons:

– Limits scope; chosen standards can’t support multiple industries

– Doesn’t address legacy integration

Approach: Generic Paradigm Translation

• Translate paradigms• Pros

– Flexible, general– Scales linearly

• Cons– Complex– Centralized; hard to

distribute

IIRA Approach: Core Connectivity Bus

• Choose “core connectivity standards”; link with “gateways”

– Fundamentally distributed– Combines other

approaches• Pros

– Can deliver performance with flexibility

– Scales linearly (only have to map each “other” to one “core”)

• Cons– Needs very functional

core standards

Can Bridge Core Standards

Core Interoperability

Functional Domain

Key Core Connectivity Functionality

• Data Quality of Service (QoS)– Delivery Reliability and re-

delivery– Timeliness Prioritize and inform

when information is “late”– Ordering Deliver in the order

produced or received– Durability Support late joiners,

survive failures– Lifespan Expire stale information– Fault Tolerance Redundancy and

failover• Security

– Ensure confidentiality, integrity, authenticity, and non-repudiation

DDS as Core ConnectivityThe Data Distribution Service Data-Centric Standard

Why Choose DDS for Core Connectivity?

• Reliability: Severe consequences if offline for 5 minutes?

• Performance/scale: – Measure in ms or µs? – Or scale > 20+ applications or 10+ teams? – Or 10k+ data values?

• Architecture: System lifecycle >3 yrs?

2 or 3 Checks?

The DDS Data Connectivity Standard

• The Data Distribution Service (DDS) is the Proven Data Connectivity Standard for the IoT

• Very functional– Any language, OS– Extensive QoS– Security– Publish-subscribe, request-reply, REST– Peer-to-peer, reliable, multicast

• DDS: open & cross-vendor– Freely available, open standard– API and Wire spec– 13 implementations

Interoperability between source written for different vendors

Interoperability between applications running on different implementations
