Why is WebRTC so disruptive?
1
x Eliminates complexity of delivering codecs and streaming protocols
x Closely aligned with HTML 5, programmed via JavaScript
x Support for mobile platforms and web browsers
x Enables real-time data communications in addition to voice and video
x Strong industry support
1
 It contextualizes communications!

What is context relative to WebRTC?
A. Data derived from interactions with a web site?
B. Transactional data stored in a business system?
C. Information derived from streaming analytics?
D. Sensor data from an IoT device?
E. All of the above?
2
Context is being combined with WebRTC to:
• Provide whitelist for who should be communicating
• Provide triggers to initiate real-time interactions
• Provide subject matter for real-time interactions
• Provide real-time feedback on what is being communicated

3
So where’s the context?
Internet Of Things
Mobile & SocialBig Data & Analytics
Systems of Engagement
Systems of Record
DB ERP
CRM HR

4
The way enterprises reach and understand
customers is rapidly evolving

Trillions 2015+

5
Integration needs are continually changing

Systems of Engagement “focus on people, not processes....These
new systems harness a perfect storm of mobile, social, cloud, and
big data innovation to deliver apps and smart products directly in
the context of the daily lives and real-time workflows of customers,
partners, and employees” source Forrester

WebRTC Middleware for the Enterprise
What is WebRTC Middleware?
 Enables scalable, secure signaling
 Web and Mobile SDKs for client development
 Gateway for SIP/IMS federation
 SIP Servlets for customization
 Media server control for media processing
 Integration with enterprise security, messaging and APIs
 Development tooling

WebRTC Application Server
• WebRTC Gateway for protocol normalization
• SIP Servlets for federation and convergence
• Media Server Control for media processing (JSR 309)
• Off the shelf services for rapid prototyping
• J2EE for accessing Systems of Record, messaging, etc.

“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).

WebRTC Application Server
SIP Servlets provide:
• A programming model for creating business logic
• A signaling bridge between SIP (calls) and analytics
• Programmable access to media servers
• Federation to PSTN, VoLTE and IMS (both enterprise and CSPs)

Media Server Control API (JSR 309) and Liberty
15
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)
