1. What’s New? What’s Different?
WebRTC vs. VoIP
What’s New? What’s Different?
@reidstidolph

2. Overview Level-Set Similarities Technical Differences
Architecture Differences
Principle Differences
Shifts in RTC

3. Voice Over Internet Protocol
“VoIP” a Broad term
Grown to encompass multimedia, not just voice
Diverse protocols
some well defined standards, some de-facto, some proprietary
Used in a variety of networks
IPv4, IPv6, Public Internet, Private LANs, etc.
SIP

4. The VoIP Universe UC Mobile VoIP Fixed Line Business VoIP
IMS
Fixed Line
Business VoIP
Consumer VoIP

5. Web Real Time Communications
Plugin-less RTC Media engine in the Browser
Purpose built for the World Wide Web
Collaborative W3C and IETF standardization
RTC as a feature, not necessarily the service or application

6. WebRTC Universe
1B devices Supported in 1Q14

7. User Experience Legacy
100 Years of Telco
20 Years of Web
Reliable, Secure, Resilient
Rich, Dynamic, Innovative

8. VoIP and WebRTC Similarities
Transmission of communication data between Users in real-time
Use RTP, SDP O/A
G.711
Run over IP networks

9. Unique Transport per Stream
Technical Divide
Opus
H.264
Codecs
VP8(?)
AMR-WB
Signaling Protocol
SIP
XMPP
Undefined
H.323

11. Principle Differences

12. Identity Telco ID Web ID Identity Management User-Centric
Network-Centric

13. WebRTC Mobility and Resilience: More Needed
Web App has no control over network changes
App
Failure
Reconnect
handover
Rehydration - automatically reestablish lost sessions
Restore call/session after browser refresh/crash
Network handoff
Device handoff

14. Shifts in RTC: Create and Extend
RTC Extension, WebRTC enabling existing comms
WebRTC as a new edge access network
Network evolutions toward NFV, Telco-OTT
Security, Interoperability, Reliability
Advance session handling
App creation toolkits for rapid service creation, prototyping
Media scaling, compliance
