Benefits of WebRTC
Democratises voice & video in websites & apps
Add context to communications & vice-versa
Cheap / easy / open-source components
Advocacy from Google, major vendors, telcos, IETF,
W3C etc
Enterprises & telcos can extend comms over the Internet
Real momentum & enthusiasm
No predefined signalling
Growing ecosystem even pre-standardisation
Realtime data even more disruptive

Better than
“being there”
Telephony aspires to be
“like being there”
“There”–
same place

The role of video in communications
Video really needs to have a clear “purpose”
We will not default to “video everywhere”
Will be even more contextualised than voice & messaging
Different issues of ergonomics, social norms, behaviour
Very little desire for interruptive straight-to-video calls
Numerous niches for B2B, B2C, C2C
Skype calls between distant relatives / expats / diaspora
Customer service but need for extensive retraining of staff
Personal consulting eg doctors, therapists, trainers, interviewers
Need for interoperability unclear as often in-

Comforting myths
Copyright Disruptive Analysis Ltd 2013 October 2013
QoS is critical
Interoperability is essential
Minutes / messages = value
![Page 17: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/17.jpg)
Uncomfortable reality
Copyright Disruptive Analysis Ltd 2013 October 2013
QoS is sometimes critical
Interoperability is essential
for lowest-common
denominator services only
Intention & outcomes = value

WEBRTC STANDARDS
AND UNDERPINNINGS

What is webRTC?
Haven’t used webRTC
Your laptop is on wifi
Have Chrome/firefox
Browse to:
http://phono.com – click ‘call’
![Page 21: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/21.jpg)
What did we just do?
Placed a video call with no plugins
zero config
just by browsing to a site
encrypted
free
over local wifi
![Page 22: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/22.jpg)
WebRTC Definition
Realtime
voice / video /data
browser based
no plugins
secure
interoperable

Standards
IETF
W3C
Loosely based on pre-existing standards
$100s Millions of IPR - donated
Google, Cisco, Mozilla, Skype, Tropo, ATT,
E///, Lucent etc.
![Page 24: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/24.jpg)
HTTP(s) signaling via webserver
Peer to Peer media between Browsers
Big Picture
![Page 25: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/25.jpg)
The IETF has responsibility for the wire
protocols in RTCWeb
Protocol standards (IETF)
![Page 26: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/26.jpg)
Signaling Standards
None! It is up to the javascript in the
browser to do what ever is needed.
![Page 27: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/27.jpg)
Media Standards (RIA 2.0)
Many! STUN
ICE
TURN
DTLS
SRTP
RTCP
OPUS
ULAW
![Page 28: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/28.jpg)
Why so many?
The network environment of a web browser is not the same as a desk phone.
Security – hostile lans (coffee shops/hotels)
Variablity – home networks, wifi/3g
Programability – Javascript is dynamically loadable
This stack of media standards addresses the differences.
![Page 29: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/29.jpg)
ICE sends multiple STUN packets down all possible interfaces to try and
find a path. First Bi-directional route found is used.
STUN and ICE address NAT
NAT NAT
![Page 30: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/30.jpg)
A TURN server in the cloud acts as a packet reflector
Many Telco 3g networks isolate users from each other.
TURN is for when ICE fails to find a viable path
NAT NAT

If additional services are required – recording, conferences, PSTN interop
etc. then bridging via a media server may be required.
Bridging via a media server.
NAT NAT
MS
![Page 32: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/32.jpg)
DTLS
DTLS is the UDP version of TLS (as used in
https etc)
It serves 2 purposes in the WebRTC
Exchange keys used by the SRTP media
encryption
Carry the data channel streams
![Page 33: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/33.jpg)
Demo – sharefest.me
Data channel provides Peer 2 Peer data between browsers.
It can be used for file transfer, game moves etc.
It may also become important in M2M or IOT as a secure NAT friendly P2P protocol.
Demo show file transfer between 2 browsers by sharing a URL, but not through that server.
![Page 34: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/34.jpg)
SRTP + RTCP
Encrypted version of the classic RTP protocol,
with the RTCP reporting mechanism.
Multiple media streams may be multiplexed over
the same pair of ports – still under discussion.
![Page 35: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/35.jpg)
Standard Codecs
Audio OPUS
Wideband
Flexible, efficient, loss correcting
Expensive to transcode
ULAW
Narrowband PSTN codec High bandwidth
Poor in lossy/variable networks
![Page 36: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/36.jpg)
Codecs - No video standard yet.
Video VP8
H264
Differences are largely commercial
and legal rather than technical, either
is plenty good enough.
![Page 37: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/37.jpg)

App/web-embedded RTC not new concept
Copyright Disruptive Analysis Ltd 2013 Oct 2013
• Expensive
• Inflexible
• Poor developer support
• Limited use-cases
• Reliance on “call” model
• Poor audio/video
• Hard to integrate
= Patchy adoption & little
developer enthusiasm / buzz
![Page 49: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/49.jpg)
WebRTC has created the buzz & excitement
Democratised the idea of realtime voice/video/data
Easy elevator pitch
“It’s like Skype – but in the browser, with no plug-ins!”
“Three simple Javascript APIs – millions can use it!”
“It’s being evangelised by Google & all these other
guys!”
Mix of (fast) standardisation & “pragmatic proprietary”
Encourages experimentation with a very low bar
Usable at multiple levels of abstraction / effort /
commitment
Carries a sense of inevitability & scope for innovation

“WebRTC isn’t a standard. It’s a movement”
Irony: problems making WebRTC stronger not weaker
“Hardcore” comms developers going “down to the metal”
Building around core RTCWeb protocols & media engine
Embedding WebRTC elements into desktop applications
Longer-tail developers being addressed by API/cloud
players
“Packaged” WebRTC capabilities like multiparty video
Abstraction to avoid risk from changing standards
APIs for iOS, Android apps
Next tier up of service platforms emerging too
Renewed interest in “realtime everywhere”
No “religion” about WebRTC “purity” – just get on with it!

HTTP to SIP – SIP in the Browser
Use javascript to build SIP messages and

Wrap in HTTP (or Web-sockets)
Send to webserver
Webserver unwraps and forwards to IMS

Problems
You still have a gateway – albeit a thin one.
You have javascript injecting SIP messages
into IMS
The SDP isn’t compatible
The media isn’t compatible
What is Early media in a browser ?
You have your SIP credentials out on the
internet.

Problems
Need to map from web Identity to SIP
Select a web identity provider
webRTC gateways don’t scale (yet)
No standard for REST messages
Home rolled protocol (may have holes)

BOSH is tested
XMPP well defined and federates

WebRTC isn’t mobile first yet.
Did we forget mobile?

WebRTC on Mobile
Browser isn’t a natural interface
WebRTC codecs are heavy on battery
No native App friendly API (yet)
SIP (if used) not an efficient mobile protocol
Audio hardware on android variable
Both Chrome and firefox on Android support webRTC
Expect to see RIA 2.0 with native APIs
![Page 78: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/78.jpg)
DTLS can carry a certificate – but which
one should be used?
Identity.
![Page 79: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/79.jpg)
Multiple identities on the web
When I call from a webpage, which identity do I want to present?
E164 to the shop
Facebook Id to my fb friends
Anon to the game
Pseudo id to dating site
Do I ever want to present facebook ID to G+ users?

For telcos, it’s all looking pretty grim anyway Downsides
Voice & SMS saturation & cannibalisation
Regulation & competitive impacts
Weak content & VAS propositions
Economic pressures
Ecosystem competition
Upsides
Connecting the last unconnected
Smartphones & data growth
Better segmentation & pricing
Innovative services & enablers
Embracing & exploiting fragmentation

Network/service coupling: historical accident
Copyright Disruptive Analysis Ltd 2013 October 2013
• Service = network
• Only 1 service
• Interop essential
![Page 86: WebRTC Tutorial by Dean Bubley of Disruptive Analysis & Tim Panton of Westhawk Ltd](https://reader033.fdocuments.in/reader033/viewer/2022052504/554b9e0cb4c905ae618b47b6/html5/thumbnails/86.jpg)
What is “OTT”?
Any capability offered “over the top” of Public Internet
Can be service, application, feature or function,
decoupled from the underlying access network
Calling OTT a “threat” misses its inevitability
Overlooks 150+ examples of “Telco OTT” services

Buys time if done well
But perceived value will fall
Accounting questions
Needs regulatory OK
Starts unwinnable arms race
Admission of being “dumb”
Add value to bundles
May be revshare upside
QoS not monetisable
Needs developer skills
Likely conflict internally
Few telcos will succeed

Conclusions
WebRTC is emerging very fast
Standards are still settling
Important to be “a part of the community”
Early experimentation is mandatory
Don’t confine WebRTC to IMS & Labs
Probably no more than 30% total WebRTC effort / resources
should go on IMS integration
Every unit in the telco with a website should be using it
Think about second-order problems now
Speed & design & purpose >> quality & evaluation
