WebRTC, for Web Real Time Communications is a free, open project to enable rich, high quality, Real Time Communications applications to be developed in the browser via simple Javascript APIs and HTML5. Major browsers already support or will support it soon natively. This talk will present an overview of WebRTC, how it is already revolutionizing the Web and changing the Telco industry. A couple of emblematic use cases will be also explored to show the potential of WebRTC in different enterprise markets and a live demo of a 1 to 1 WebRTC Video Conference will also be performed followed by a detailed explanation on how it was achieved as well as what JBoss AS7 additions were required to make it work

HTML5 WebRTC for Real
Time Communications

What's HTML5 WebRTC anyway


JBoss AS7 HTML5 WebRTC Support with

Q&A

4. Real Time Communication in
your Web Application
l
Ever felt of adding voice, video, IM ….. Real Time
Communication to your Web Application?
l
How did you solve it?
l
Lets have Demo

5. Real Time Communication in
your Web Application
RestComm
l
Historically Web and Telecom were different
l
Telecom technologies are inaccessible to most developers
l
Not any more
l
Web technologies are open & ubiquitous
l
Millions of web developers world wide

6. API to telephony network
l
A User calls or sends an SMS/IM to your number

7. API to telephony network
l
RestComm receives the call or SMS or IM and makes
request to your application

8. API to telephony network
l
l
l
Your app receives all the information regarding call like
called party number, calling party number etc etc
Process the information
Sends XML back

9. API to telephony network
l
RestComm follows the instruction and controls the flow of
call

10. RestComm enables WebRTC
WebRTC Use Cases
■Browser to Browser or PSTN Audio Calls
■Browser to Browser Video Calls
■Video Conferencing
■Messaging (Chat) for Remote Support Widgets or M2M
Communications
■ScreenSharing for Remote Support or Collaboration
■File Sharing
■Video VoiceMail

11. What's
anyway ?

12. Mission Statement
l
l
l
WebRTC is a free, open project that enables web browsers
with Real-Time Communications (RTC) capabilities via
simple Javascript APIs.
Think rich, high quality, RTC applications in the browser via
simple Javascript APIs and HTML5 without plugin
The WebRTC initiative is a project supported by

13. Developer Stance
Defines a set of Media and Data JavaScript APIs
to bring VoIP natively to the browser and cross
platforms :
l
GetUserMedia
l
(camera and microphone access)
l
PeerConnection
l
(sending and receiving media)
l
DataChannels
l
(sending non-media direct between browsers)

14. Architecture

15. HTML5 WebRTC Signaling
and Media
• WebRTC is
•
independent of
WebSockets
Can use anything
for call control
signaling including
Ajax, server push
or plain HTTP
• Media is peer to
peer and can
handle both audio
and video
(RTCWeb)

17. What is
?

18. The
Approach
Web / Mobile
Application
Developer

19. From Legacy PSTN to
Cloud Communications

20. HTML5 WebRTC
Integration

21. Goal
l
Since WebRTC = VoIP, makes sense to support in the
largest Open Source Communication Platform, no ?
l
Handle large number of concurrent connections
l
Allow Interop with existing VoIP or Telco Infrastructure
l
Since WebRTC doesn't define the call control signaling, choice
was to use SIP as signaling protocol (there is a draft for that)

22. Server Side
Awesomeness

23. JBoss AS7 Adds-Ons
• Automatically adds WebSocket support to any JAIN SIP based server (SIP Stack used by
Mobicents and Google Android 2.3+)
o SIP Servlets http://dev.telestax.com/sipservlets/
o SIP Stack http://dev.telestax.com/jain-sip/

24. WebRTC Support
In Java EE7 ?
• No but next revision of SIP Servlets Specification (JSR 359)
will support it.
• Deliver support for reusable Converged Web and Real Time
Communications Applications
• RTC Applications can leverage Java EE6 Technologies and
Standards all the way
• Existing Applications can adds RTC Capabilities easily

25. Client Side
Coolness

26. SIP JavaScript Stack
l
l
JavaScript Framework allowing HTML5 Applications to
that handle Call Control (SIP) in the Browser
Contributed by

27. SIP JavaScript Stack
Still ugly (to web developers) Low Level SIP details for now but working on higher abstractions, ie 1 liner
import and 1 liners to place call, reject, hangup etc

28. Future
Work
