History repeats:Re-build an IoT hourglass model

IPv6

• So IETF has worked hard to capture the requirements and align back on IPv6 (the scalable version of the Internet):

• IPv6/802.15.4

• IPv6/ITU-T G.9959

• IPv6/BLE

• IPv6/DECT-ule,

• IPv6/NFC, Foo, DetNet, …

IoT Hourglass model isn’t enough

• Many organizations are (re)defining terms for basic concepts like temperature and on/off within their own namespace, which then becomes an inseparable part of the data model.

• Different protocols are available to address different use case requirements

• Data models tied to dedicated protocols result in all-or-nothing interoperability

• Common protocols but often different application semantics and data models

IoT technologies != Internet Technologies

PUSHING A SQUARE PEG IN A ROUND HOLE

• In IoT devices

• Bandwidth is 250 kbit/s, not 250 Mbit/s

• Program memory size is 256 kB, not 256 MB

• Requires a scale down 1000 x of:

• Protocols complexity

• Packets traffic

• IoT is not a scaled down version of the whole Internet!

IoT still suffered of a huge fragmentation issue!

• But the richness of higher layer protocols are still at the origin of the fragmentation in IOT

• More work is needed to get to achieve higher layer interoperability and reusability.

An world composed of a complex mix:

Small communities (resulting in project often quickly starting but quickly fade out too)

Fragmented solutions (many OSS projects that each solve 20% of a problem but cannot be used together)

Hidden gaps (sometimes critical functionality with too few eyes on them resulting in security flaws)

But which manages to:

Leverage a vast community

Innovating at a very fast pace

Sometimes resulting in de facto

Challenge of Open Source Software (OSS)

• Common goal is to make

it easy for devices to

connect and

interoperate - regardless

of vendor, OS, hardware,

etc.

= Interoperability

IoT Device Interoperability

The Strategy for Building Device Interoperability

Specification Open Source Project Certification

• Broad spectrum of industry leaders providing guidance

• Common communications protocols, approaches for security and identity, and service-level protocols, object models & developer APIs

• Open specification that anyone can implement

• Provides a fast path to market for developers and manufacturers

• Open source development promotes faster innovation via community driven development

• Connectivity framework that abstracts complexity

• IP protection & branding for certified devices

• Certification = a device implementation as defined in the specification and released into the open source

OIC is a specification & open source project that delivers “just-works” interconnectivity for developers, manufacturers and end users.
