DESCRIPTION
Unless you’ve been living under a rock for the last 2 years, you’ve heard of WebRTC. But unless you’re at the bleeding edge of technology within your organization, you likely don’t know a lot about the details of WebRTC, either from the technology or the business-case side. This Workshop, led by one of the world’s recognized authorities on the WebRTC industry, will help you get your bearings on this important subject. The first portion of the Workshop will give you a basic technology tutorial: What is WebRTC, how is it implemented, and what are the current challenges? This will be aimed at familiarizing you with the main concepts of WebRTC, and why it has become such a hot topic. The second portion of the workshop will help you understand the promise that WebRTC holds for the industry as a whole: The developer ecosystem that is arising around WebRTC; the early successes that implementers are having, and how WebRTC is likely to affect the enterprise. You’ll come away from this Workshop with an action plan to take back to your organization, to prepare your enterprise for the impact of WebRTC and to take full advantage of it. The Workshop will be presented by Tsahi Levent-Levi, one of the industry’s most recognized and best-read analysts for the WebRTC space. Tsahi tracks and shapes the WebRTC debate on his own website, Blog.geek.me, as well as on No Jitter and other venues. He is uniquely positioned to offer valuable insights on how WebRTC will impact your organization, and how you can prepare for it.

WebRTC is a Technology
not a Solution
Where are we Headed?
1. What is (and isn’t) WebRTC
2. Anatomy, VoIP & WebRTC
3. Where Enterprise Meets WebRTC
4. The WebRTC Ecosystem
remember: a Technology. Not a Solution
WHAT IS (AND ISN’T) WEBRTC
WebRTC offers real time communication natively
from a web browser
WebRTC is a media engine with JavaScript APIs
How Are Calls Made With WebRTC?

Isn’t it Just Like… SIP
???
Yes, but without any Signaling
So What?
No Plugins No Downloads No Installations No App Store
No Signaling Free (as in BSD) No Patents No Media Eng.
What Does it Provide?
• Real-time
• Voice, video and data
• Browser based
• No plugins
• Secured
• Interoperable (between browsers)
Why All the Fuss?
I heard Internet Explorer doesn’t support it
Where?
1.2 Billion Enabled devices
14
Told you Internet Explorer is missing
This will never fly!
How Do We Solve Browser Support?
• Ignore
– Offer the service on supporting browsers only
– Videodesk.com isn’t showing the capabilities
– popexperts blocks such browsers from access to the actual service
• Plugin
– Build a plugin for non-supporting browsers
– AddLive and Weemo do that
• Downgrade to “Flash”
– Use Flash where WebRTC doesn’t work
– Apidaze took that approach
• Don’t use WebRTC at all
Someone told me mobile is eating up PCs
Why do I need WebRTC there?
Mobile and WebRTC
Our Routes to Mobile
1. Ignore mobile
Who needs it anyway?
2. Only run on supported browsers
Works well for ad-hoc support/sales use cases
3. Port and pack as an app
Everyone and his wife does that today…
A Story of Mobile & WebRTC
Hello Santa offers live one-on-one video calls with
Santa Claus. Calls can be placed on iPhone, iPad,
or any computer with an Internet connection. After
each call the customers gets a Video Souvenir, a
recording of the video call that they can keep for
themselves, or share on Facebook and Twitter.

Who took my signaling?
Signaling options in WebRTC
Technique Who is it for? Why?
SIP over WebSockets VoIP diehards It connects to their “existing” backend
XMPP/Jingle XMPP fanatics Because it does XMPP
WebSockets Fashionista WebSockets is the latest and greatest in
client-server web communications
XHR / Comet Ubiquity seekers Because WebSockets isn’t supported
everywhere
Data Channel Thrill seekers WebRTC’s data channel is an unexplored
territory that can be used for signaling

Transport
• Media transport based on SRTP
• No RTP at all
• “Latest and greatest” of RTP got mandated
– AVPF
– Multiplexing
– Etc.
Media
• No Mandatory to Implement (MTI) video codec. Yet…
Codec Use Specification
G.711 Narrow band, selected for
PSTN and VoIP interworking
RFC 3551
Opus New flexible audio codec.
Narrow to wideband
support; Support for
Speech & Music
RFC 6716
DTMF Telephone events RFC 4733
VP8 Google’s open source
codec
RFC 6386
H.264 Video codec (MPEG-LA
licensing)
RFC 6184
NAT Traversal
• “Almost” like SIP
– STUN – Enables announcing your public IP addresses during the
negotiation phase of a session
– TURN – Relays all media via a TURN server that is visible to all parties in
the session
– ICE – Decide on the best solution to send media (direct, STUN or TURN)
• Trickle ICE – Speed up the process of the ICE protocol by
parallelizing its handling of candidates
– New specification, implemented in WebRTC
– Slowly trickling into SIP and XMPP

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.

– Had no real-time support to speak about
– Controls the end-to-end experience
Unified Communications
“ What Unified Comms?
Checking the calendar for this week I see that I have
11 UC meetings enabled on four different UC
platforms – only one of which my employer
supports directly.

What Roles can WebRTC Play in UC?
1. Put WebRTC in the MCU
– Any video call from WebRTC into the enterprise goes through the MCU
– Takes up ports, and doesn’t realize the power of WebRTC
2. Put WebRTC in the SBC
– A gateway of sorts, but with “improved” security
– Still not using the power of WebRTC
– Also – WebRTC doesn’t have any real use for an SBC
3. Use a Gateway for WebRTC
1. Works, but still – not using the power of WebRTC
Why not Reverse the Picture?
• Place WebRTC at the heart of the network
• Place SIP and H.323 at the edges instead
• Can this bring back control of UC to the enterprise?
