Background
• 2006– CERN room refurbishments
• RCTF (Remote Collaboration Task Force)
• 2007– EVO no longer free (DoE budget cuts)
• 2008– ATLAS and CMS significant contributions
• EVO Oversight Board
• 2009– LCEB (LHC Collaborative Environment Board)
• Service provision responsibility transferred to CERN-IT• (EVO commercial offering; one amongst others)
– Selection of product• Q1: Establish LHC Experiment requirements• Q2: Market assessment; 20 potential, 4 retained

Vidyo
• Business– Venture capital startup (2008)– Google; Gmail video chat– Cisco, Hitachi, Teleris– Apr 2010 HP announced strategic partnership with Vidyo– Numerous awards; “the next big thing”
• Technology– Developed H.264/SVC video compression standard– Granted patent “System and Method for a Conference
Server Architecture for Low Delay and Distributed Conferencing Applications”
• Avoids centralised MCU (multipoint control unit)• Low latency, increased quality, network error tolerance• Automatic scalable bit rate adaption• Automatic scalable resolution adaption

Vidyo Pilot: phase I
• 2009 Aug– Vidyo Pilot purchased; 50 ports & 50 licences
• 2010 Apr– LHC experiments agreed to test Vidyo– LCEB defines 2 month pilot (May-June)– Experiments to answer on 1st July
• “Does Vidyo meet your needs?”
• Vidyo Pilot setup extended– 100 ports & 400 licences– Audio bridge– Beta release Linux client provided

Vidyo Pilot: results
• Technical issues– Login/download problems
• CERN certificate handling issue
– Linux client problems– No chat functionality– Wide scale test (>50) not performed
• ALICE: “accepts Vidyo can serve their needs”• LHCb: “testing positive”• ATLAS
– “feedback positive, quality higher than EVO”– Linux client and chat mean cant conclude yet
• CMS– “When users connect, audio & video better than EVO”– Is promising but not ready yet for LHC production
• LCEB: extend pilot, run systems in parallel

Vidyo Pilot: plan
• Extend pilot with goal:– Linux client at same level as other platforms– Meet maximum scale (500 connections)– IT to test as well as experiments
• Setup– 100 ports, 650 licences– MCU bridge to allow EVO and Vidyo clients– Audio bridge
• Timescales– Linux client GA in September– Router cascading GA in November– Experiments to express result... End of year?
