web-rtc presentation on TNC 2013, Technical Advisory Committee meeting
- 1. Jan Meijer UNINETT eCampus & TTC member TNC 2013 webrtc why you should care
- 2. background: eCampus programme ● national programme ● enable more effective teaching and research in higher education ● use IT to effect attitude and workflow change ● deployment deployment deployment ● for the 99% ● systemise, rationalise, scale up
- 3. the synchronous comms soup ● SIP, UC, MS Lync, Cisco Jabber ● H323, $$$ video conferencing rooms ● Skype, Google Hangout, Facebook, whatshallwecallit ● web conferencing, AdobeConnect, WebEx etc.
- 4. 5 video feeds is enough for....
- 5. functionality ● audio ● video ● screen sharing ● application & desktop sharing ● document sharing ● chat ● recording
- 6. web-rtc ● browser based real time audio, video and collaboration without plugins ● open standards based ● IETF RTCweb: on-the-wire protocols ● W3C Web Real-Time Communications Working Group: Javascript API spec
- 7. +------------------------+ On-the-wire | | Protocols | Servers |---------> | | | | +------------------------+ ^ | | | HTTP/ | Websockets | | +----------------------------+ | Javascript/HTML/CSS | +----------------------------+ Other ^ ^RTC APIs | |APIs +---|-----------------|------+ | | | | | +---------+| | | Browser || On-the-wire | Browser | RTC || Protocols | | Function|-----------> | | || | | || | +---------+| +---------------------|------+ | V Native OS Services
- 8. ietf deployment models ● browser-browser media path, with signalling in backend ● with server multiplexing signals
- 9. functionality ● real time audio ● Opus (RFC 6716) mandatory-to-implement audio codec ● OPUS: high fidelity codec for both voice and music, bandwidth scalable ● «WebRTC clients SHOULD include an AEC» + gain control ● real time video, ongoing » discussion» on mandatory-to-implement video codec, H264(5?) vs. WebM/VP8 ● screen sharing, document sharing etc.
- 11. implementation status ● IETF: ... ● W3C: last call working drafts Q2/Q3 2013, recomm. 2014 ● Mozilla and Google on board ● supported in Google Chrome and FF Beta ● MS involved but waiting for standard to settle ● Apple tracking closely but keeping cards close to chest ● FreeSwitch: support in prod. from summer ● BigBlueButton open source web conf prototype (UNINETT, NorduNet funded) ● Buzz at telecom conference
- 12. ● based on functionality it looks & smells like web conf but will be so much more! ● chunks in the soup or new soup? ● «As the available bandwidth has increased, and as processors and other hardware has become ever faster, the barriers to participation have decreased, and it has become possible to deliver a satisfactory experience on commonly available computing hardware.»
- 13. that's what web-rtc is now to what it might mean (my crystal ball)
- 15. disruptive innovation theory (Clayton Christensen)
- 16. disrupting web conferencing ● prediction: current web conferencing products will not be able to adapt but they will try ● business models dictate evolutionary innovation ● too much investment in current product tech stack ● their tech stacks suck underperform exactly where web-rtc rules offers better functionality ● won't be able to offer sufficient user experience for acceptable price ● AdobeConnect, WebEx, BlackBoard Collaborate will be irrelevant in a couple of years ● Clean slate species (startups) will take over. Old ones die or become zombies ● Current products not integration oriented
- 17. disrupting standard vidconf ● much cheaper MCU/multiplexing functionality with equal quality (see MCU port prices vs. web conf seat prices) ● standard room based systems sell you all-in- one package: microphone subsystem, camera, TV, speakers + call set up & media transport. Take out the latter! ● addressing with vidconfroom.uninett.no
- 18. disrupting UC? ● billion end points with good quality audio/video? ● lower barrier of entry in UC market ● client side audio and video quality no longer product differentiators ● better inter-op between vendors: end to lock-in? ● reduces UC to directory + software-based MCU + integrations with other enterprise infra
- 19. what does this mean for us? ● «17 GEANT partners currently offer a managed webmeeting desktop service (up from 14 in 2011). The most commonly used platform is AdobeConnect» ● «29 of the GEANT partner NRENs provide or plan to offer a centrally managed video- conferencing service, which clearly indicates the strategic importance of videoconferencing» ● «1/3 of GEANT partner NRENs currently offe a centrally administered VoIP service» source: 2012 TERENA compendium
- 20. Opportunities! ● webrtc ought to make real time comms a lot cheaper ● and a lot easier to scale to 99% of the users ● UC1 integrating with all functionality with UC2? ● easy video calling finally achievable? ● easy group conferencing for the masses ● support research communities: web-rtc integrates nicely with web based tooling used by research groups, solving the «lonely researcher» problem? ● new products & services will come with new possibilities!
- 21. what to do?
- 22. communication goal tool eyes on the prize!!
- 23. Jørgen Yri ● linguist, teaches Spanish ● collaborates across borders ● with various institutions in .no ● with various folks outside ● he wants ● easy to give access, regardless of formal home ● «a certain stability» ● easy screen and document sharing ● no heavy installs for students ● works on different platforms «without too much tinkering» ● not a lot of budget ● wants stuff that works, but need not be perfect ● doesn't care about tools
- 24. the market provides? ● target group? ● conditions? ● cost? ● time-to-deliver? ● public procurement?
- 25. Stuff to do? ● track closely: learn the tech, imagine the business. ● You have probably 2 years to still look on top of things ● Remember disruptive theory also applies to YOU ● prepare your users ● be ready when web-rtc hits: start then and you'll miss the party (costing your society) ● revisit your (class) room specs, decouple AV install from transport ● Geant Campus Best Practices, Physical Infrastructure ● plan for new procurement requirements and know when to introduce them ● try! Run trials! vidconfroom.uninett.no! ● UNINETT is considering organising a follow-up on BigBlueButton web-rtc sponsoring
