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
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

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

WebRTC Mobility and Resilience:
More Needed
Web App has no control over network changes
• Rehydration - automatically reestablish
handover

lost sessions
• Restore call/session after browser
refresh/crash
• Network handoff
• Device handoff
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
