3 And that platform is about to be dwarfed Massive surge in connected things has already begun By 2020, 40.9 billion things will be connected * Via Wi-Fi, wire line, cellular, and proximal networks Benefiting billions of people worldwide 75% of the growth between today and the end of the decade will come from non-hub devices Transforming: Industry Infrastructure Media Education Work Recreation Family Daily life AllSeen Alliance 3 * Source:

5 Ubiquitous connectivity promises to make devices smart But ONLY if they speak the same language hello world! 당신은 내 말 들려? Tem alguém aí? Computing devices Consumer goods and appliances Home Auto Industrial Devices that can t connect across brands, categories, and operating systems will be left out 5

6 Network topology matters Someone s at the door Someone s at the door Laundry is ready! Someone s at the door Laundry is ready! Coffee is done Coffee is done Direct communication is fast, efficient, and secure. No need to go out to the cloud to talk to the device right next to you! NOW PLAYING: Artist: Flowers Song: Daisy 6

7 Internet of Things Tomorrow Secured Proximal Cloud NOW PLAYING: Artist: Flowers Song: Daisy Various Cloud Services 7

8 What are these things of which you speak? Without the right combination of hardware, connectivity and software a Thing is just a Thing. Ultimately it is software that makes a Thing an Internet-of -Things Thing. 8

9 APIs - how software talks to software Well constructed software has clean boundaries between the internals of the implementation and the external interfaces exposed to other software. We generally call these external interfaces Application Programming Interfaces (APIs) APIs are what makes it possible to incorporate existing functionality into new code Software platforms are simply collections of APIs Windows, Linux, Android, ios, OSX are defined by the APIs they provide Examples abound - OpenGL, PhysX, Webkit, every social network on the planet! 2 December 2014 AllSeen Alliance 9

10 APIs for IoT devices IoT devices are characterized by the software they run so: When IoT devices talk to IoT devices it is software talking to software IoT devices should have APIs But these IoT devices are all so different But often have very similar functions What APIs should IoT devices have? Some standard APIs Some device specific APIs 2 December 2014 AllSeen Alliance 10

11 IoT needs a framework to expose the various APIs of connected devices in a consistent way. A single platform allowing products to expose their capabilities LOCK DOORS DISPLAYS LIGHT BULBS SPEAKERS GARAGE DOOR CLOCKS SENSORS COOL PICTURES HEAT VIDEO TVs DRAPES The AllJoyn software framework is a collaborative open source project of the AllSeen Alliance 11

12 Devices describe their capabilities via discoverable self-describing service interfaces I can send notifications. I have control panel I have a clock interface I can send notifications I display notifications. I have the clock interface! I display notifications. I have the clock interface! I can send and display notifications I can send notifications I have control panel I display notifications. I have the clock interface! I have lighting interface The AllJoyn software framework is a collaborative open source project of the AllSeen Alliance 12

13 Standards What we don t want: There s an App for that thing And an App for that thing And yet another App for that thing Devices that have similar functionality should expose the same APIs Every device with a clock should expose a set-clock API Every device that has a battery should expose a battery level API Manufacturers cannot differentiate by exposing necessary functionality in different ways 2 December 2014 AllSeen Alliance 13

14 Exposing smartphone APIs enabled new experiences - that no one had ever thought of GPS MICROPHONE GPU TOUCHSCREEN ACCELEROMETER DSP GYRO 14

15 The problems to be solved in an open interoperable way DISCOVER nearby friendly devices IDENTIFY services running on those devices ADAPT to devices coming and going MANAGE diverse transports INTEROPERATE across different OSes EXCHANGE information and services SECURE against nearby bad actors 15

16 Baseline for an API framework for IoT Must be designed to work with existing programming languages Java, C, C++, C#, JavaScript, Python, etc Must support modular construction To allow standard building blocks To allow innovation Must include facilities for discovery Find out what APIs a device has rather than what the device is Must support privacy and security Which APIs can be used by other devices Authentication and data encryption 2 December 2014 AllSeen Alliance 16

17 The AllJoyn Project An Open Source Framework for the Internet of Things 17

18 A year ago a group of companies formed the AllSeen Alliance A nonprofit consortium dedicated to enabling the widespread adoption of products, systems and services that support the Internet of Things through an open environment, vibrant ecosystem and thriving technical community. Hosts and advances an industry-supported software and services framework based on the collaborative AllJoyn open source project. This collaborative open source framework enables hardware manufacturers and software developers to create interoperable products that can discover, connect and communicate directly with other devices, systems and services regardless of brand. 2 December 2014 AllSeen Alliance 18

20 AllJoyn Software Framework: High-level architecture A comprehensive software framework lets devices and applications communicate AllJoyn App Layer Defines the User experience AllJoyn Service Frameworks Interoperable, cross-platform modules for common IoE functionality Defines common interfaces between devices AllJoyn Core Libs Provides ability to find and connect to devices to do interesting things. Core libraries interact with the AllJoyn Router Provides access control and encryption Onboarding Notifications Discovery & Advertisement APIs AllJoyn Apps AllJoyn Application Layer AllJoyn Service Frameworks Control Panel Standard Application Layer Audio Lighting AllJoyn Core Libs Connection APIs OS Config Interface APIs AllJoyn Router Physical Layer (Wi-Fi, PLC, Ethernet, Bluetooth) Events and Actions. Security APIs AllJoyn Router Manages communications between devices and apps Dynamic network management The AllJoyn software framework is a collaborative open source project of the AllSeen Alliance 20

21 Two Versions of the AllJoyn Framework To Choose Standard App Layer App dev or OEM writes this Standard Apps App Layer AllJoyn Standard Service Frameworks Standard Application Layer Thin Apps App Layer AllJoyn Thin Service Frameworks Standard Application Layer Thin App Layer OEM writes this Standard Core Libraries Multiple bindings, runs on HLOS AllJoyn Router AllJoyn Router can be bundled with a Standard App or run standalone AllJoyn Standard Core Libs AllJoyn Router HLOS AllJoyn Thin Core Libs RTOS Physical Layer (Wi-Fi, PLC, Ethernet, Bluetooth) Thin Core Libraries C bindings, runs on RTOS Thin Apps using Thin Core requires an AllJoyn Router in the network The AllJoyn software framework is a collaborative open source project of the AllSeen Alliance 21

22 Open source building blocks for value added services Use AllJoyn Core Library and Service Frameworks to create differentiated offerings Not licensed under open source; addresses specific use cases Value Added Services (e.g., your differentiation) AllJoyn Core: Discovery, connectivity, network management from AJ Router + core libraries AllJoyn Service Frameworks Onboarding Control Panel Notifications Audio Config Future Onboarding, notification, audio compatibility from AllJoyn Service Frameworks AllJoyn Core Libraries Discovery Connection / Network Management Security AllJoyn Router Licensed under open source; general IOE use cases 22
