AbstractTelephone networks set a high standard for real-time communications. As

the new WebRTC standard makes its way into web browsers, enterprises and service providers are evaluating its potential to deliver real-time voice, video, and data over the internet with public switched telephone network (PSTN)–equivalent reliability, quality, and security. Learn in this session how Oracle customers are deploying WebRTC-based voice, video, and data-sharing services and enabling a communications experience that integrates e-mail, instant messaging, Twitter, and other forms of web-based communications

WebRTC @ Glance

WebRTC offers real time communication natively from a web browser 61%

WebRTC capable browser share, including Mobile, Tablet and desktop

API WebRTC is a “Media Engine” with javascript API

WebRTC is a technology, NOT a solution

So, what is WebRTC - Technically Speaking?• Collaborative W3C and IETF standardization

• A built-in application program interface that enables browser-to-browser applications for:– voice calling– video chat– peer to peer data

• Media engine in the browser, accessed by JavaScript, downloaded from web-server

• No defined signaling mechanism

• No MTI coded media

Advanced Contact Center

• User benefits– Connect immediately to an agent (no IVR) using

the browser’s media capabilities– No more click-to-call or call back required– Use computing device as a phone– Answering my questions quickly and efficiently

• Enterprise benefits– WebRTC embeds RTC capabilities directly into

web pages– Browser context (page view) info can be shared– Drive down the cost, no need of physical phone– Integration with Social Network / BigData– Pull your customer to your website

Cost Savings: Overall savings of $17M per year over a 5 year period on communication and marketing costs

Environments: Enterprises with Customer Care


Deployment Example: Amazon Mayday

• How WebRTC is used– Enables voice, video, and other forms of

collaboration– Well-integrated into Kindle device (no

special setup; no exposure of WebRTC technology to end customer)

• Benefits– Face-to-face engagement with high

value customers– Ability to reach customers that always

require live help

What is WebRTC Missing?WebRTC Chasm

Current WebRTC

• Security – Identity, authentication and authorization

– More user name and passwords

– Network Denial of Service

• Reliable network solutions– Lose sessions on browser refreshes or network issues

– Lack of support for large networks with many sessions and many connections

• Interoperability– Between networks

– Browser and devices

– Voice and video media

– Policy, charging, or internet traversal


Security – User Identity, AuthenticationStandard Web-based or Telco AAA Mechanisms

Identity

Network

WebRTC

Attack

• Client identity/authentication - OAuth• Coordinates identity across multiple sessions• Telco/enterprise authentication mechanisms• Network identity - encryption keys &

network authentication• Prevents network overload/DoS• Traffic prioritization maintains normal service

to valid users


Reliability – Failure/RecoveryPersistent Sessions, High-scale Signaling & Media

N+1 Stateful HA Scalable Clusters

OCWSCOCWSCOCWSCOCWSCWebRTC WebRTC

reconnect• Rehydration – persistent session, re-

establish connection– Intermittent network connectivity– Browser crash or reload

• Highly-scalable software-based SRTP termination

• Distributed high available signaling and media architecture for carrier-grade scalability


Interoperability – MediaIntelligent Media Routing

Web AppWeb App Web AppWeb App

Network Anchored

Media

OCWSC

P2P

• Conditional media anchoring– Peer-to-peer if a media path exists – “Anchors” media if no path exists– Preserving/augmenting ICE and DTLS – Based on WebRTC SDPs

• Dynamic media release improves scale & bandwidth allocation

• WebRTC media to network interworking– Encryption– Codec transcoding & mediation


Interoperability – Any Device/Any Network

• Network handover– Roaming between networks– Optimal use of bandwidth

• Device handover– New interface– New IP– Update media address to peer

Rehydration Maintains Session Between Devices or Networks

Interoperability - Network, Encryption

• Highly adaptive WebRTC to SIP/IMS– Data manipulation– Process orchestration

• Application/network policies– Policy and Charging Rules Function (PCRF) SDP

manipulation: message handling, codec enforcement, application black/white lists, session limits, etc

– Media policy support for bandwidth, signaling and media resource allocation

– Broadband policy management integration with PCRF
