Vidyo at CERNSwisscom – CERN meeting – 9th April 2013

Universal Videoconference with Vidyo

• Videoconference at CERN• Vidyo@CERN: scale and infrastructure• Service Access• Service Support• Integrations• QA processes• Future plans

Videoconference at CERN• H323 rooms since early 00’s

• Now ~70 equipped rooms

• H323 MCU services• Collaboration with French CNRS on MCU

service• Own service since 2007 (based on Codian

MSE8000)

Videoconference at CERN• EVO since the late 90s• Built on the requirements of HEP communities• Tender needed in 2008 following EVO’s change of

business model• Setup of a committee with representatives of major user

communities• Establishing requirements• Informal market survey• Only two products could cope with specs• Pilot for 6 months

• Selection of Vidyo• 1st January 2013: end of EVO support at CERN

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

CERN Vidyo Service Scale

• ~20000 users• 800-1600 simultaneous connections• 21-168 simultaneous H323 (rooms)• 12 simultaneous recordings

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

Service Support

Service Support• Major disruptions

• Related to Vidyo bugs• Mostly on gateways: h323 disconnections• Linux clients

• Related to infra configuration• Badly set firewalls: regular disconnections• Reached maximum connections: saturated router pools

• Related to integration issues• Indico integration: users isolated in meeting «islands»• Status notification server

• 2.5h down time in March

• Related to peripheral services• Phone.com initial failures

Service Support

• Users training• Internal CERN technical training

• Users information• How to best use VC in general• Best equipment

Integrations• CERN users database

• Synchronisation script running every 30 mn• Using Vidyo web service APIs• Using LDAP link option on portal

• CERN Indico server• Direct call to Vidyo web service APIs

• CERN Vidyo dashboard• Direct SQL queries to CDR DB

• Infrastructure monitoring interface (in progress)• Added Nagios to all servers• Calls to the CDS DB

• Weekly meetings with Vidyo• Keep sync with service changes• Discuss issues

• Beta tests of new features• Defined set of tests (~200) executed before

any upgrade• Portal• Client• Integration

• Staging environment
