2. What is the big deal with
WebRTC ?

 Provides Multimedia communication through browser API’s alone
 No custom software , hardware
 No plugin , installations , extensions
 Standardized byW3C and IETF
 IETF RTCWeb WG ( Internet world, IP protocols)
 W3C WebRTC WG (web world, Browsers etc.)
 Supported Browsers
Chrome Firefox Opera
 Supported Mobile Platforms
Android iOS

3. How does WebRTC Call work ?
4/19/20153
 Signal
 Web Server/service based signaling brokering
 Offer/Answer JSEP ( Java Session Establishment Protocol )
model with SDP ( Session Description Protocol )
 protocol NOT defined
 Media
 Peer to peer media flow
 SRTP/RTCP
 Firewall and NAT/NAPT
 Uses ICE for STUN /TURN mechanism

Signalling Protocol
WebRTC can utilize any web transport and has no
specified signalling mechanism .
•JSON
•REST
•SIP over Websocket
•Proprietary signalling
•Any other HTTP based signalling

17. Concerns ?
4/19/2015
Altanai Bisht . website:http://
altanaitelecom.wordpress.com17
 Firewall / policies blockage
 NAT issue is major ICE is complicated
 setup own STUN or TURN server
 Security
 SRTP / web breaker / DTLS too much and too ambiguous for a developer
 No one talking about - SPAM control / Unwanted call screening / risk mitigation
 RTP stream multiplexing
 RTP + RTCP
 Conferencing involves Multiple RTP streams. No standard network topology to work
 Interworking
 Simple to call between WebRTC bowers ( full audio and video )
 Confusion on integration with OTT solutions (Skype, Viber, Google Jingle , XMPP
etc.)
 SBC ( Media transponders and Proxy servers ) have demonstrated interworking with
NGN/IMS
 More clarity required on integration with legacy PSTN and PLMN . Even GSM / UMTS
as they have different number formats ( ENUM can be used ) ISUP and legacy
codecs .

18. Legal Issues ?
4/19/2015
Altanai Bisht . website:http://
altanaitelecom.wordpress.com18
 Who is hosting the comm platform?
 Identity resolution for authentication?
 Detecting the service
 man-in-the-middle attacks
 Network sniffing ( users location , device and call activity )
 Lawful interception required in many Organizations
 Session Replay
 Media Interception
 Tough to track where is signal passing through in IP network?
 Media Encryption (DTLS) Who has the keys ?
 Media Server employed to force relays adding to complexity
 RTP multiplexing is hugely a black box
