Technical Principles for an Internet of Things Ecosystem Open Interconnect Consortium, Inc.
Scope of IoT Controller OIC Scope OIC Scope (anticipated) (current) Controller App Cloud Interface Cloud Servers Cloud Servers service #2 service #1 domain domain Things Controller Controller Local Control Remote Control Server to Server 4
Approaches for defining and interacting with Things OIC Scope • Imperative : By defining functions • Declarative : By defining things as resources and its properties of and operations on things SetSwitch BinarySwitch - Power(in) - true(on), false(off) Resources Dimming SetDimmingLevel Functions - properties - dimmingSetting (int) - Input & Output Parameters - step(in), range(in) - step (int) - range [0-100] Brightness SetBrightness - brightness (int) - brightness (in) e.g., Light bulb - (no Verbs) + Objects - (Verbs + Objects) * Fixed set of verbs (CRUDN) from transport layer - RPC model will be used - Resource model in RESTful Architecture (e.g., W3C, CSEP, etc.) 5
Additional Considerations* • Late Binding (Reliability, Resilience, Conformance) • Multi-Protocol • Peer – Peer (Gateway and Cloud are not first class citizens but peers) • Framework as middleware • what defines the ecosystem (is it only spec?) • Need consistent behavior • Adaptability • Optimization (e.g. sensors, connectivity) OIC Member Confidential Information 5/22/2016 6
Support of Multiple Verticals • Legacy vertical services usually designed as silos Home Health Domain No common way to communicate among them OIC Scope Insulin level low! … Need Help! Health Home Industrial … Health Home Industrial Discovery Common Platform Addressing Messaging Security Health Home Industrial … • A common platform provides a foundation for vertical services to collaborate and interwork Smart Home Domain by providing common services and data models 8
Interoperability • Full interoperability from the connectivity layer up to the service layer is the only way to truly guarantee a satisfactory UX • Interoperability at the Connectivity and/or Platform layer only provides partial interoperability which can ultimately lead to fragmentation ② Platform Level ③ Service Level ① Connectivity Level Interoperability Interoperability Interoperability Vertical Vertical Vertical Vertical Vertical Vertical Services Services Services Services Services Services Platform Platform Platform Platform Platform Platform Connectivity Connectivity Connectivity Connectivity Connectivity Connectivity OIC Scope 9
Interoperability & Certification • Conformance test - Each device proves conformance to specifications • Interoperability test - Each device proves interoperability with other devices OIC Scope Conformance Test Certificate Issue CERTIFIED & Logo Licensing Interoperability Device under Test Test Prerequisites: Dependency Certification (e.g. Connectivity) • Certification Scope Tested Optional Tested Mandatory Optional Optional Open Optional Open Spec (in spec, cert & committed Source Spec Source Features in Open Source Project) Features Features Features Open Source Specification 10
Licensing OIC Scope For IPR Policy : e.g. RAND-Z, RAND, etc… • For Open Source : e.g. Apache2, Internet Software Consortium (ISC), etc… • Due to the common nature of IoT connecting everything over the Internet, it’s • most critical for manufacturers to avoid a licensing risk - Everything connected could be at potential risk Offering manufacturer-friendly Licensing and IPR Policy enables growth of • market by attracting both start-ups and large enterprises; such an IPR policy must be clear and readily understandable ensuring that the terms are offered by all IP holders. 11

Core Framework Specification Overview Open Interconnect Consortium, Inc.
Objectives • Core Framework Specification Scope • Specifies the technical specification(s) comprising of the core architectural framework, messaging, interfaces and protocols based on approved use-case scenarios • Enables the development of vertical profiles (e.g. Smart Home) on top of the core • Architect a core framework that is scalable from resource constrained devices to resource rich devices • Evaluate technical specification(s) for maximum testability and interoperability • Ensure alignment with OIC open source releases 19

Organization of an OIC Device • OIC Device – abstraction on a platform to host resources and execute roles Resource URI: /oic/p rt: oic.wk.p if: oic.if.r /oic/p n: homePlatform policy: bm:11 /oic/res /oic/res pi: at1908 /oic/d /oic/d mnmn: Samsung /oic/ad /oic/mnt OIC Device 1 OIC Device 2 Physical Device e.g. light bulb Mandatory Optional 22
Device example: light device (oic.d.light) • Example overview - Smart light device with i) binary switch & ii) brightness resource • Device type: Light device (oic.d.light) [Defined by the domain] • Associated resources - Core resources: ① oic/res, ② oic/d - Device specific resources: ③ Binary switch (oic.r.switch.binary), - Other optional resources can be exposed, in this example ④ Brightness resource (oic.r.light.brightness) Example: Smart light device with 4 resources Device Device oic/res Associated Resource Type M/O Title Type oic/d oic/res (oic.wk.core) M Binary switch oic/d ( oic.d.light ) M Light oic.d.light Binary switch (oic.r.switch.binary) M Brightness Brightness (oic.r.light.brightness) O 24
Core Framework Specification Key Features Open Interconnect Consortium, Inc.
OIC Spec Features – Core Framework Spec ① Discovery: Common method for device discovery (IETF CoRE) Vertical Industrial ② Messaging: Constrained device support as Smart Home … Profiles Internet default (IETF CoAP) as well as protocol translation via intermediaries OIC Core Framework ③ Common Resource Model: Real world entities defined as data models (resources)\ ⑥ Group Protocol ID & Addressing ④ CRUDN: Simple Request/Response mechanism management Bridge/GW with Create, Retrieve, Update, Delete and Notify commands ③ ④ ⑦ ⑤ Common Device Resource CRUDN Security ⑤ Device Management: Network connection management Model settings and remote monitoring/reset/reboot ① ② functions Discovery Messaging Streaming ⑥ ID & Addressing: OIC IDs and addressing for OIC entities (Devices, Clients, Servers, Resources) ⑦ Security: Basic security for network, access control L2 Connectivity Networking Transport based on resources, key management etc 26
OIC Core Framework Basic Operation Discovery Operation Discovery - Discover access policies, device info and resources on the devices Operation - Get device information by retrieving resources - Control devices by changing resources - Observe change on the properties of resources Basic common capabilities - Device Monitoring - Maintenance (e.g., reboot, factory reset, statistics collection, etc.) Connectivity Networking Transport Security 27
