What is WebRTC?
(and why you should care)
What is WebRTC (Real Time Communications)?
Emerging method of web-based RTC Another type of access framework Why the hype?
Web: most dynamic, innovative place on planet RTC has largely been absent WebRTC delivers RTC to those that create the Web Why should you care?
WebRTC will be an important access method in the future for SPs, contact centers, and enterprises 4
Level set
What is The Web?
A distributed system overlaid on The Internet Made up of interlinked text, images, videos, and other multimedia “hyper”media Over 640,000,000 websites on The Internet
Who makes the Web?
Web developers: the largest dev. community on Earth
What makes up the Web?
Made up of servers, databases, and browsers Loosely linked using protocols and techniques HTTP, PHP, JavaScript, MySQL, HTML5, CSS, Python, REST…and more!
The Web is very different from traditional communications networks such as IMS, UC, the PSTN 5
WebRTC
The World Wide Web gets eyes and ears Real Time voice and video woven into The Web Acme Packet SDN enables Enterprises, Service Providers, and OTTs to join the revolution 6
What is WebRTC?
Is it WebRTC or RTCWeb?
Both!
(kind of)
WebRTC
is the name for
W3C
efforts
RTCWeb
efforts is the name for
IETF
Standard Standard What is the purpose?
To enable Real Time Communications (RTC) in The
Web
environment What is all the hype about?
Web environments
and
innovative
are the most
dynamic
places in technology…but
RTC has
largely
been absent
WebRTC delivers the power of RTC directly
into the hands of The Web

WebRTC (technically speaking)
A powerful set of audio/video communications tools Best of breed echo canceler Audio/video codecs Video jitter buffer, image enhancer SRTP stack Peer-2-peer tools for NAT STUN, TURN, ICE
…all built into your web browser!
These tools are utilized by Web developers Accessed via JavaScript 8
The media engine of WebRTC
Still being finalized VP8 vs. H.264 highly debated G.711 and Opus are mandatory voice codecs Video codecs not yet set SRTP and STUN/ICE/TURN
Required
Voice Codecs G.711
Opus Video Codecs VP8 H.264
Transport DTLS-SRTP SDES-SRTP STUN ICE TURN Multiplexing 9
The signaling of WebRTC
Traditional Role of Signaling is the
information
concerning the
namespace, establishment, control, and billing
of a
communication session
.
WebRTC has no traditional signaling channel!
Channel It relies on a Web, or Traditional Signaling ?
Billing Info ?

Session delivery challenges
WebRTC NOT Exempt
• • • • Security • Authentication and authorization • Confidentiality • • DoS and overload protection Identity management Service reach • Interoperability and interworking • • IPv4 <-> IPv6 Firewalls Service assurance • QoS • Reliability Regulatory compliance • Lawful intercept • Call recording 12
Security
All the challenges/vulnerabilities of Web-based applications Remote code execution Format string vulnerabilities XSS (Cross Site Scripting) Username enumeration PLUS Real time communications Toll fraud/theft of service Eavesdropping Session overloads (SPIT) SPAM over Internet Telephony Session hijacking 13
Regulatory compliance
• Adding WebRTC to SDN means NO compromise on compliance for applications that require it • Web-to-Call Center • • Web-to-Emergency Svc.
Web-to-Financial Institute • Web-to-Service Provider
Call Center UC Banking IMS Hosted UC Emergency SVC
• • Lawful intercept Call recording 14
WebRTC Use Cases
SP subscriber access via WebRTC methods Browser-based RTC to complement SIP offerings Enterprise UC without thick or thin client soft phones Easier to maintain & break single UC vendor lock Contact centers embedding RTC into customer service web pages Customer satisfaction & lower costs SIP WebRTC 15
WebRTC vs. SIP: Bridging a Great Technology Divide

WebRTC: New Access Framework, Same Session Delivery Challenges
Service reach • Interoperability and interworking • Firewall/NAT traversal • Peer-to-peer vs. core transit
Service provider, enterprise & contact center
• Security • Authentication & authorization • Confidentiality • • DoS and overload protection Identity management • Service assurance • Availability & reliability • QoS, QoE • Regulatory compliance • Call recording • Lawful intercept SIP WebRTC 17
Addressing BYOD & enterprise mobility challenges
UC devices today use SIP or proprietary methods WebRTC 1 & HTML5 will play a role in BYOD/BYOA But, new access methods must coexist with SIP based UC infrastructure & device… …and Acme Packet helps coexistence
UC devices today: SIP, SCCP, H.323, UNIStim, etc.
Emerging devices & apps of tomorrow
Note 1: WebRTC is used here in a generic context to refer to any type of browser- or web-based real-time collaboration (RTC) app. The term “WebRTC” is a specific term used to describe an approach driven by Google but there are many other comparable app or browser driven RTC approaches 18
Enterprise UC & CC Use Cases
How WebRTC helps contact centers
WebRTC embeds RTC capabilities directly into web pages No more click-to-call or call back required Uses the browser’s media capabilities to directly establish customer-agent session (over-the-top, not via PSTN) Browser context (page view) info can be shared with agent
Voice / video / browser view context shared between customer & agent CRM Customer WebRTC-enabled website page ACD/ PBX Agent
20
How WebRTC helps enterprise UC
Provides UC on any device with a WebRTC-compatible browser Allows for browser-based UC independent of UC client vendor Doesn’t require a thick UC client to be installed & maintained RTC apps on employee devices Seamless & secure remote worker access via secure WebRTC methods Has potential to be compatible with existing enterprise UC system Enterprise UC System 21
WebRTC + multi-vendor UC
WebRTC endpoints must seamlessly interconnect to existing UC clients & servers WebRTC Session Director ensures interop between WebRTC signaling & media and existing enterprise UC systems WebRTC signaling methods (i.e. SIP over WebSockets or REST Existing Enterprise UC signaling methods (i.e. SIP) WebRTC Endpoint (third-party UC app) WebRTC-associated media methods (i.e. SRTP & STUN, TURN, ICE)
