10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 1 Reality Check – Collaboration in the Real World Agenda –History of video conferencing at Fermilab –Current status –Support issues –Trouble-shooting Experiences

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 2

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 3 History of Video Conferencing at Fermi ISDN Fermi joined LBNL in ESnet ERVN Pilot Project –Dedicated resources carved out of ESnet backbone 196 Kbps video, 32Kbps audio –Pilot project became production ESnet VCS. Dial-up ISDN resources reserved through telnet sessions –ISDN community expanded as codec cost declined –Fermi assigned 1FTE for video conferencing Primary responsibilities are resource scheduling and MultiSession Bridge (MSB) operation

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 4 History of Video Conferencing at Fermi ISDN (cont’d) From VCS to DCS –Fermi VCC, RCWG, et al collaborated with ESnet developers on web interface for scheduler –User requests centralized to VCC DCS to ECS –By 1/2004 ~200 standing meetings entered into DCS –Decline of ISDN-based video conferences

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 5 112kbps video, 16kbps audio

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 6 Packet-based Video at Fermi MSB –HEPNET/NRC created MultiSession Bridge (MSB) HEPNRC created VUPAC: shared a/v resources in conference rooms with codecs & workstations 128kbps video, 64kbps audio Problems: –Assigning video operators –Connections made from command line –Poor audio due to rat tool without echo cancellation –Remote users required to request connections –Poor quality for sites with low bandwidth –No effort to bring remote mbone video into local room –MSB use declines Decommissioned in 1999 Conference room workstations decommissioned

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 7 Packet-based Video at Fermi VRVS –VRVS used for LHC CMS meetings Initially desktop mbone tools only Web interface created New features continually added VRVS release supports H.323 for use in conference rooms –Users must provide own PC to start session –Interoperability problems with H.323 products

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 8 Ad-hoc: 320kbps video, 64kbps audio VRVS: varies

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 9 Current Status Twenty-one video rooms, all H.323 IP systems Approximately twenty desktop H.323 systems Majority of meetings use Ad-hoc bridge 1 FTE –Customer service –Coordination in conference room design & installation –Training –Consultant to on- and off-site FNAL users –Testing new technologies.3 FTE – multimedia consulting –data communications infrastructure installation

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 10 Current Status (cont’d) Approximately two new video conference rooms appointed per year Latitude- audio/data collaboration Declining number reserved by VCC Data collaboration utilization unknown

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 11 Current Status (cont’d) What we’ve gained from H320 to H323 –ISDN charges ~$1K per month Prior to migration ~$14K per month –FTE level of operational support reduced by 50% –Mixed modes. Gateway to IP bridge allows POTS and ISDN participation –Flexibility with no set start times and no time limitations –Widened understanding of collaboration and tools –Desktop connectivity –Ease of use, control of meetings is passed to users

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 12 Current Status (cont’d) What we’ve lost with H320 to H323 migration –Control of meetings passed to users Widened understanding of technology not yet quite wide enough –ESnet-provided site/endpoint utilization statistics –Decentralization of room scheduling and technical support At Fermi Division/section personnel support was waning prior to IP migration and scheduler change No ESnet Operations Call Support, only Room, endpoint and contact information, dial-in #s for point-to-point meetings

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 13 Support Issues Conference room support Operations –Includes start-up assistance –Maintenance of equipment and peripherals –Procedure documentation, system configurations –Back-up support Room design and installation –Test new technology and tools –Desktop video conference support TBD

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 14 Support Issues (cont’d) VCC –Back-up support –Testing new technologies –Eventual gatekeeper operation

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 15 Trouble-shooting Experiences or A Day in the Life of a Video Conference Coordinator Problems are typically due to pilot error Examples: Microphone placement too close to speakers or speaker volume too high Incorrect speed selected Wrong number dialed or unknown Peripherals not powered on Cables not properly connected

10/27 thru 29/2004 ESnet Collaboration Workshop - Sheila Cisko/FNAL 16 Trouble-shooting Experiences (cont’d) Technical problems –Example Immediate system error message requires reboot »In ViaVideo remove port#s from gatekeeper IP address »Use tools (ping, traceroute or ?) to check status of on- and off-site systems User endpoint is non-supported client
