In order to provide the type of services their customers crave, your clients need to be able to provide blazing fast communication capabilities and access important information in the blink of an eye. WebRTC (Web Real-Time Communications) allows for the creation of next-generation communication applications without the need for browser plugins. WebSphere Application Server Liberty Profile is changing the way people communicate by making it easy to provide web page context as part of real-time conversations. This webinar will cover all of the real-time communications features recently released in WebSphere Liberty, including the new Rtcomm feature for rapid development of WebRTC based applications, and the open-source Rtcomm client-side libraries.

4. What is WebRTC?
 Enables real-time data in addition to voice and video.
 Closely aligned with HTML 5, programmed via JavaScript.
 Eliminates complexity and licensing cost of delivering codecs.
 Widespread industry support.
 Enables contextual communications!
WebRTC offers web application developers the
ability to write rich, realtime multimedia applications
on the web, without requiring plugins, downloads or
installs. (source www.webrtc.org)

</featureManager>
• Adding additional rtcomm configuration to the server.xml:
<rtcomm
messageServerHost=“<brokerhostname>”
messageServerPort=“<brokerportname>”
rtcommTopicPath=“/rtcomm/”>
<iceServerURL>stun:example1.hostname.com:8880</iceServerURL>
<callQueue callQueueID=<queueID>></callQueue>
</rtcomm>

15. Why MQTT for Liberty Rtcomm Signaling?
• Open, lightweight, secure and highly scalable
• Simple authorization through MQTT topic ACLs
• Clients available on mobile platforms and JavaScript
• Simple IoT integration
• Extensible through JMS
14
Rtcomm over MQTT for massively scalable signaling
MQTT vs. HTTP/REST
• 93x higher throughput
• 1/10th battery
• 1/8th bandwidth
Stack size comparison
SipML5: ~5 MB vs. MQTT Paho + Rtcomm: ~ 250K
Visit http://mqtt.org/ for more info.

16. • The Rtcomm protocol is JSON based and designed for messaging
• The protocol is open and defined here: http://bit.ly/1GiodaX
• Shared Subscriptions used to distribute messages across multiple
subscribers for clustering, call queues, etc.

traversing firewalls.

22. SIP Servlets 1.1 (JSR 289) now supported on
WebSphere Liberty
21
“The Session Initiation Protocol (SIP)
is a signaling communications protocol,
widely used for controlling multimedia
communication sessions such as voice
and video calls over Internet Protocol
(IP) networks.” (source: Wikipedia).

25. Media Server Control API (JSR 309) and Liberty
24
The Media Server Control API is intended to provide multimedia application developers with a
generic Media Server (MS) abstraction interface. It defines both a programming model and an
object model for MS control independent of MS control protocols. (Source: JSR 309 Specification)
