  1. 20th March 2015 Evolutions in the CERN Conferencing Landscape

  2. Conference rooms Webcast 1 2 4 3 Indico Vidyo Conference rooms Webcast Vidyo Indico

  3. Conference Rooms Design, installation of new rooms, renovation of old ones Maintenance of all room equipment User support in the room Coverage

  4. Conference Rooms • InforEAM • Equipment inventory and tracking • Maintenance tracking

  5. Conference Rooms • Extron GVE • AV equipment monitoring, alerts, automated actions

  6. Conference Rooms • RAVEM (Room AV Equipment Manager) • Centralised equipment control • Python, Django, MySQL (DBonDemand) • Examples: • Proxying rooms connections to Vidyo • Switching “on-air” signs

  7. Conference Rooms • Service dashboard (http://avc-dashboard.cern.ch ) • User/customer facing status interface • Drupal, Google charts, HighCharts

  8. Conference Rooms • Security • Networked devices: projectors, controllers, PCs etc. • Access protection mandatory • Wireless communication encryption • End user protection • Subtle simplicity/security ratio • Ex.: on-air signs in the VC rooms

  9. Conference Rooms eq./room data equipment/room information equipment status history equipment live status equipment connection request equipment control equipment live status User facing interfaces equipment live status

  10. Conference Rooms What’s Next ? • Investigating wireless data transmission • Bluetooth, wifi • Proprietary protocols (EPSON QuickConnect, INTEL WiDi) • Lack of standard, but some ongoing consolidation • More remote controls and monitoring options • Online physical locks for meeting rooms

  11. Webcast & Recording 272 • Live webcasts / Recordings • Streaming for on-demand videos (hosted on CDS) • 16 rooms equipped at CERN

  12. Webcast • Wowzacommercial streaming software • Streaming, transcoding • Commercial CDNs for large events • Limelight, Akamai, GroovyGecko

  13. Webcast CERN domain transcoding + relay streaming edge 1 main origin edge 2 10 Gbps encoder device DNS balancer wowza.cern.ch edge 3 HTAR … general webcast backup origin edge 16 physical servers Meyrin CC virtual servers Meyrin CC conference rooms Infrastructure

  14. Recording • Micalarecording software • CERN/U. Michigan licence • Manages the workflow up to the publishing in CDS

  15. Video Workflow • Submission of video clips to CDS • Ingest from web upload, DFS hot folder, Vidyo recording; transcoding; browsing

  16. Webcast What’s Next ? • Improved subtitling options (separate subtitles file) • A webcast web site for mobiles • Towards new streaming standards • mpeg-dash: adaptive bitrate streaming over http • to reconcile desktop and mobile viewing • Central operation center • Currently each room has its own control interface

  17. Vidyo • Multiplatform videoconferencing service • Desktops (linux, Mac, windows), mobiles (iOS, Android), phones, H323

  18. Vidyo • Infrastructure • 2 portals • 26 routers • 14 gateways (in 3 clusters) • 12 phone access points • User satisfaction survey

  19. Vidyo News Recording feature in production Service monitoring (CERN development)

  20. Vidyo News VidyoWeb for guests (MacOS and Windows) New router in South Africa Deploy SSO and Lync gateway Vidyo replaces Alcatel MyTeamWork as official CERN audio conference service

  21. Vidyo What’s Next ? • Ongoing discussions with GEANT to propose a service to worldwide research and education based on CERN infrastructure. • Using VidyoRoom hardware in CERN meeting rooms instead of H323 devices? • WebRTC • Interesting emerging standard for embedding VC in the web browser • Vidyo to come up with a devkit to build dedicated clients (a solution to Linux issues?)

  22. Indico • Event organisation and archiving system • At CERN • 331000 events

  23. Indico at CERN User satisfaction survey

  24. Indico • Ongoing transition away from ZODB and to PostgreSQL (using abstraction layer SQLAlchemy) • Release 2.0 foreseen end 2015 • Better integration with collaboration services • Better plugin management • New e-payments options (bank transfer and EUR/CHF for CERN) • Rich abstract editor (LaTeX/Markdown) • E-tickets

  25. Indico Outside CERN 164 institutes have an Indico server worldwide

  26. Indico Distribution • KT project #1 (2013-15) • New visual identity • New web site / video • Instance tracking feature • Cloud deployment scripts

  27. Indico Global Service CERN IEEE SWITCH … CERN IEEE SWITCH CAP CAP • KT project #2 (starting 2015) • Supporting communities in Indico

  28. Common Frameworks • All software packages developed by the services • Are published under a GPL v3 licence. • Use git / github / gitlabfor version control • Use Jira / githubfor task management • Use/have plans to use the Wigner computer center resources for business continuity solution.
