What is WebRTC?

WebRTC is an API definition drafted by the World Wide Web Consortium (W3C) to provide peer-to-peer applications for voice, video and data sharing

Goal: point-to-point or multipoint voice, video and data communication without browser plugins using JavaScript

Most peers today are devices running compatible web browsers but other devices such as WebRTC mobile devices are coming

WebRTC is considered a disruptive UC technology by many

Standards and Browser Implementations

WebRTC standards development:

IETF standardises the on-wire protocols

W3C standardises the API

Compatible browsers (Oct. 2013)

Google Chrome >= 23

Mozilla FireFox >= 22

Ericsson Bowser

Opera (Mobile) >= 12

Why is it Considered Disruptive?

Very easy to integrate UC in new or existing web applications using JavaScript

Based on open standards i.e. non-proprietary

Peer-to-peer media streaming i.e. no intermediate server involved in media streaming

The next wave of UC:

Wave 1: fully proprietary UC products

Wave 2: free, proprietary UC products such as Skype and Google Hangout

Wave 3: WebRTC-based products

Extremely fast pace of evolution (Internet speed)

Includes a minimum base set of royalty free codecs!

WebRTC Stumbleblocks?

Microsoft’s CU-RTC-Web technology (Internet Explorer)

Co-existence is the norm today (gateways)

Apple’s silence (Safari)

Alternative browsers are available

Mobile browser support (anti-Google?)

WebRTC can be bundled with apps

Traditional Telco's and their often old-style business models

WebRTC should be seen as an opportunity

Potential WebRTC island formation

Federation and island-hopping is already in

No signalling!

Use what you know/prefer.
