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?
