Integration
• Goal: maximize the ease of use of all collaboration tools offered in the service
• Video and phone conference integration:– Avoid the duplication of the IO devices in the
room (microphones, loudspeakers)– Provide a coherent connection interface– Through the same hardware
• Video: standard IP H323 connections (ESNet, Hermes, VRVS, EVO)• Audio: SIP connection (IP) to CERN PABX (direct phone call, eDial
system)
– Mixed (bridging): possible if the room device has MCU (multipoint control) capabilities

Service Activities
• Meeting room equipment– Equipment testing (Polycom, Tandberg, Aethra)
• New features: HD; People on Content…– Standardization:
• Tandberg• Supports both video and phone conference with same system (SIP)• Offers both performing table and ceiling microphones
– Possibility to add electronic whiteboards (Smartboards for remote lecturing)
– Provide advice on room equipment, supervise installation– Provide advice on room furniture (carpeting, curtains, lighting)
• Online status display– http://it-multimedia.web.cern.ch/it-multimedia/Rooms/

Service Activities
• Recently refurbished
40-R-B10 (CMS)
40-4-C01 (ATLAS)
936-R-035 (AB)
CCC glassbox (AB)
513-1-024 (IT)

Service Activities
• Meeting room equipment maintenance– Use of management tool for video-conference endpoints: TMS
• Monitoring and alarms (SMS, email, etc)• Management: Central push of SW updates• Reset the settings (nightly) using templates• Statistics of usage
– Use of software management tool for VC room PCs: CMF• Management: Central push of SW updates• With MOM package for PC status monitoring (adapted from CC)
– Monitoring and alarms (SMS, email, etc)
– Projection devices• Network connected (devices more expensive)• Bulb life-time and life-cycle

Service Activities
• User Support ([email protected])– On-call first line support; debug problems (service contract, 1 person), or
to help start meetings– 2nd line support (1 fellow, 1 PJAS)– Increasing number of rooms should lead to reinforcement of 1st line
• User Training– Developed to decrease the need for 1st line support and improve the user
experience• Room equipment tutorials: 3x ATLAS, 2x CMS• EVO tutorials to be timed for its lunch (1 each for ATLAS/CMS)
– Developing new supports:• Room printed guides• Online tutorials• Live tutorials
• Hiring a VC engineer

Event Management
• Indico: Meeting management Hub– CDS Agenda migration completed
• Integration of VC features ongoing– VRVS done (Aug 2006)– EVO soon– CRBS: Physical room booking done (May 2007)– HERMES and eDial booking soon
• World-wide installations– FNAL, IN2P3, ILC– Collaborative developments
• e.g. Time-zone awareness

New CRBS
• Booking process requires less actions• Easy access to:
– You bookings and pre-bookings– The rooms you manage
• A lot of parameters by which to find a room meeting your needs

VRVS/EVO Infrastructure
• VRVS– Manage 4 VRVS reflectors
• 2 for internal CERN• EVO migration June
– Robustness, modern interface, ease of use
– Fully redundant architecture; mirrored at CERN (DB, web server)
– Manage 2 Panda reflectors• Support and operation
provided by CERN/Caltech agreement– PJAS: World-wide
VRVS/EVO system operation
VRVS Meetings for HEP collaborations up to May 2007

H.323 Infrastructure
• ESNet– Hardware change: All Codians MCUs (which our oldest
rooms setups are not able to use - ESNet or Hermes); Tandberg gatekeeper
– Outsourced support
• HERMES (aka RMS)– Operate MCU in collaboration with IN2P3, CNRS and
INSERM (and INRA)– Hosted by the ccIN2P3 in Lyon (72 ports)– http://cern.ch/it-multimedia/HERMES.htm – New videoconference recording device

Audio Conferencing
• Alcatel PBX and eDial system (IT-CS)– Automatic audio conference system (24/7)– Fully redundant architecture– Integration with VC via SIP gateway– Scheduled and ad-hoc meetings

Select/Recommend: DeskTop
• Desktop videoconference (under study)– Tests of audio devices, webcams in view of
standardization and distribution through the stores• To be added to CERN stores catalogue and advertise
– Tests of desktop videoconference applications (eg. Polycom PVX, Tandberg MOVI)
• Possible discussion for group licences
• Web conferencing (WebEx, MS Office Live Meeting…)

Service: Webcast & more
• Webcast– Study of the replacement/improvement of the
existing CERN webcasting infrastructure• Replace current HW with newer, redundant, more
performant HW• Review the choice of download format
• Issues– Obsolete rooms (and lack of available ones)– VRVS bad audio setups with no echo suppression– VRVS frequent overload (db server)– ESnet overload (all ports used)– ESnet gatekeeper instability– Fine-tuning of the newly installed equipment
