1 1st TF-WebRTC meeting Uninett WebRTC activities Stefan Otto Paris

2 UNINETT Sanntid group sanntid (norwegian) - realtime National SIP infrastructure: Institution located gateways Kamailio and Asterisk based (B2B) Connects to local classic telephony switch Connects to local MS Lync installations as SIP-trunk Central SIP-trunk to one PSTN-provider

3 Lync Growing number of institutions with Lync Attractive conditions for the education and research sector In fact it is the only one UC solution with impact Central Lync solution in 2015 supported by Uninett What relevance has Lync for WebRTC?

4 Lync MS announced on blog.skype.com ORTC API for WebRTC in IE becomes reality Announced Skype for Web Rebrand Lync -> Skype for Business Announced already in March 2014 WebRTC support for their development platform for Lync

5 Lync development platform Lync mobile Lync web app My web app Lync desktop client UCWA UCWA Media plug-in UCWA JS OM UCWA Media plug-in HTTP UCWA Audio Video Presence... SIP UCMA Audio Video Presence... SIP Lync server

6 Work done by Uninett this year Examine WebRTC technology Follow standardization effort (ietf/w3c) Get overview over WebRTC related projects and evaluate meaning for our sector Build a proof of concept communication solution in order to get experience with related on the wire protocols (TURN/STUN/ICE) signaling protocols (SIP / json / xmpp /...) WebRTC browser API Build SIP-WebRTC gateway for audio conference Establish an experimental videoconference solution Build «proof of concept» comm. solution with integration to our common authentication service (feide)

7 Webrtc - first steps

8 Webrtc - first steps Based on easyrtc Node.js as signalling server Easy use of WebRTC API STUN / TURN server

9 WebRTC video conference based on Jitsi / Jitsi-meet meet.akademia.no Quite impressive and good feedback Easy deployment ( apt-get ) TURN: rfc5766-turn-server from google Chrome / Opera only Browser updates imply problems :(

10 WebRTC communication client Serverside: Runs on a virtual platform debian wheezy node.js (user profiles / communication with UWAP) signaling xmpp (prosody) rfc5766 TURN server Clientside UWAP authentication / groups / searching p2p audio and video WebRTC file sender p2p WebRTC chat (xmpp based) Buddylist

11 WebRTC SIP gateway WebRTC-SIP gateway: Kamailio Asterisk Webrtc2sip (doubango telecom) Freeswitch... Client-side: SIPml5 Jssip Sip.js SIP WebRTC-Client PSTN / SIP world WebRTC-SIP gateway SIP WebRTC-Client

12 WebRTC Use Cases and interesting projects

13 Use case p2p networks - Torrent client for the browser / node TOR-node combined with a torrent-client Video streaming Create your own network protocol / topology Use of DHT for network topology / routing can be used for signal-infrastructure or for replicated/distributed DBs

14 Use case PeerCDN Content-server Client1 Client1 Client1 Client1 Client1 Client1 Client1 Client1 Client1 PeerCDN.com acquired by yahoo

15 Kurento.org WebRTC media server + a set of client APIs Group communications, transcoding, recording, mixing, broadcasting and routing of audiovisual flows Mediapipline consists of MediaElements Sink and source Filter or mediaendpoints Gstreamer based (also opencv) Clients: Java / Javascript / JSON-RPC
