Overview
Level-Set
Similarities
Technical Differences
Architecture Differences
Principle Differences
Shifts in RTC
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
The VoIP Universe
UC
Business VoIP
Fixed Line
Consumer VoIP
Mobile VoIP
IMS
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
WebRTC Universe
1B devices Supported in 1Q14
User Experience Legacy
100 Years of Telco
20 Years of Web
Reliable, Secure, Resilient
Rich, Dynamic, Innovative
VoIP and WebRTC Similarities
● Transmission of communication data between Users in real-time
● Use RTP, SDP O/A● G.711● Run over IP networks

handover
• Rehydration - automatically reestablish lost sessions
• Restore call/session after browser refresh/crash
• Network handoff
• Device handoff
Web App has no control over network changes
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
App creation toolkits for rapid service creation, prototyping
Media scaling, compliance
Advance session handling
