WebRTC offers real time communication natively from a web browser
WebRTC is a media engine with JavaScript APIs

WebRTC is a Technology
not a SolutionTheBusyBrain
Which WebRTC?
20/10/2014 6
WebRTC is both an open source project and a standard specification
webrtc.org
• The open source project
• Holds an implementation of the
WebRTC specification
• Can be used by anyone for
anything
And also openWebRTC.io
WebRTC 1.0
• The standard specification
• Not yet completed
• Handled by the IETF and W3C
Where?
1.47
BillionEnabled devices

A Change in Mindset
Brain: How are going to get the Earth to lose weight?
Pinky: I know! We can get everyone to go on a diet!
Brain: Diets don't work.
Pinky: Not even if you call them 'A Whole New Way of Eating?‘
Brain: No.

Interoperability
• All products use the same network interface
• Targeted at 100’s of vendors
• Requires much IOT testing
API
• All developers use the same programming interface
• Targeted at building a developer ecosystem
• Built on a small set of base implementations
• Each vendor has his own island of a service
