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

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
