  1. Swisscom – CERN meeting – 9th April 2013 Vidyoat CERN

  2. Universal Videoconference with Vidyo Videoconference at CERN Vidyo@CERN: scale and infrastructure Service Access Service Support Integrations QA processes Future plans

  3. Videoconferenceat CERN • H323 roomssinceearly 00’s • Now ~70 equippedrooms • H323 MCU services • Collaboration with French CNRS on MCU service • Own service since 2007 (based on Codian MSE8000)

  4. Videoconferenceat CERN • EVO since the late 90s • Built on the requirements of HEP communities • Tender needed in 2008 followingEVO’s change of business model • Setup of a committeewithrepresentatives of major user communities • Establishingrequirements • Informal marketsurvey • Onlytwoproductscouldcopewithspecs • Pilot for 6 months • Selection of Vidyo • 1st January 2013: end of EVO support at CERN

  5. Vidyo at CERN • Since December 2011 • Universal videoconference system • From Vidyo clients (connection through Vidyo routers) • Desktops (Windows, MacOSX, selected linux flavors) • Mobile devices (iOS and Android) • From 3rd-party clients (through Vidyo gateways) • Rooms (CERN VC rooms) to the H323/SIP protocols • Phones • Strong points • Extensible (several hundreds in a single meeting) • Very small latency (natural interactions) • Good A/V quality and resilience/adaptability to poor network conditions • Simple interface • Good integration possibilities

  6. CERN Vidyo Service Scale ~20000 users 800-1600 simultaneous connections 21-168 simultaneous H323 (rooms) 12 simultaneous recordings

  7. Vidyo Eligible Users • Anyone with a valid CERN account • Register at https://account.cern.ch/account/“Services” link • can participate in meetings • create virtual rooms • invite other users • moderate meetings • Non-CERN users • can participate as guests

  8. CERN Vidyo Worldwide Service Topology Portals 2 Routers Router 20 Gateways 10 Proxy

  9. Vidyo: Usage Evolution

  10. Vidyo: Usage Evolution

  11. Usage Evolution • Currentpeaks • max Simultaneous connections: ~750 • max number of people in one meeting: 252 • max phone usage: 100k minutes in 1 month • more than 3200 meetings per month • more than 5000 distinct users and 3000 Guests per month • more than 18000 clients have been installed (mobile and desktop)

  12. Indico Service

  13. Indico Service • THE CERN hub for event management • Meeting and conference organisation (schedule, document management, registration, e-payment, etc.) • Central repository and long-term archive of event-related documents • Physical room bookings • Collaboration services bookings • Chat interface

  14. Indico – Events Management

  15. Access From Desktops • IndicoVidyo portal • Participants • Managers

  16. Access from CERN Meeting Rooms Room VC equipment This PC

  17. Access from non-CERN meeting rooms IVR: dial gateway IP CERN or Internet2

  20. Service Support

  21. Service Support • Major disruptions • Related to Vidyo bugs • Mostly on gateways: h323 disconnections • Linux clients • Related to infra configuration • Badly set firewalls: regulardisconnections • Reached maximum connections: saturated router pools • Related to integration issues • Indicointegration: usersisolated in meeting «islands» • Status notification server • 2.5h down time in March • Related to peripheral services • Phone.com initial failures

  22. Service Support • Userstraining • Internal CERN technical training • Users information • How to best use VC in general • Best equipment

  23. Integrations • CERN usersdatabase • Synchronisation script running every 30 mn • UsingVidyo web service APIs • Using LDAP link option on portal • CERN Indico server • Direct call to Vidyo web service APIs • CERN Vidyodashboard • Direct SQL queries to CDR DB • Infrastructure monitoring interface (in progress) • AddedNagios to all servers • Calls to the CDS DB

  24. QA Processes • Weekly meetings withVidyo • Keepsyncwith service changes • Discuss issues • Beta tests of new features • Defined set of tests (~200) executedbeforeany upgrade • Portal • Client • Integration • Stagingenvironment

  25. QA Processes Staging

  26. QA Processes Beta tests

  27. VC/Vidyo use cases • Standard • Work meetings • Point2point calls • Distance learning • Recruitment interviews • Challenging • Remote Operation Centers • CERN Collaborations Meetings • Public outreach: Masterclasses

  28. Service Evolution New client withintegrated chat - Q2 2013 New phone access points in CERN collaborating institutes - 2013 Skype gateway – Q2 2013 Linux consolidation – Q2 2013 Recording – Q3 2013 Webcasting Infrastructure virtualisation SSO?
