Why is WebRTC so disruptive?

x Eliminates complexity of delivering codecs and streaming protocolsx Closely aligned with HTML 5, programmed via JavaScriptx Support for mobile platforms and web browsersx Enables real-time data communications in addition to voice and videox Strong industry support

2

It contextualizes communications!

3

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?

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

4

So where’s the context?

Internet Of Things

Mobile & SocialBig Data & Analytics

Systems of Engagement

Systems of Record

DB ERP

CRM HR

5

The way enterprises reach and understand customers is rapidly evolving

Contact Center

Trillions 2015+

6

Integration needs are continually changing

7

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

So what are Systems of Engagement?

Enterprises MUST be prepared to apply personal (customized) expectations on their IT systems.

So what does all this have to do with WebRTC?

Greater customer satisfaction than non-WebRTC users

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

“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

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)
