Agenda
Virtual Internet2 Member Meeting (VIMM)
Internet2 Commons
Monthly Virtual Briefings
Virtual Internet2 Member Meeting
Virtual Member Meeting
In-person meeting planned for September 30-October 4 in Austin, TX
Concerns about travel safety following September 11 tragedies
Decision was made to replace in-person meeting with a virtual meeting
Planning
Once the decision to go with a Virtual Meeting was made, we had 10 days to make it happen
Initial VIMM program included a one-day plenary session on October 2
Quality of the production – MPEG-2 baseline – was driven by the opportunity to broadcast on the ResearchChannel satellite feed <www.researchchannel.com>
Plenary Technology
Real at 128K, 256K, 512K using Akamai
H.323 - Multipoint Control Units (MCUs)
VRVS
IP/TV (MPEG-1), Amnis (MPEG-2), Ncast (MPEG-2), RTPtv (MJPEG)
Access Grid
ResearchChannel – Source and destination
Audio-only conference call

A Growing Agenda
H.323 videoconferences started being scheduled for the same week
Decision was made to include a “limited” number of track sessions
Result: three days of concurrent track sessions, including Megaconference, October 3-5
VIMM Statistics
Over 90 individuals presented during the VIMM
Out of 36 planned track sessions for Austin, 22 were presented virtually
Some VIMM sessions had higher attendance than similar sessions at our in-person meetings
We received 7,494 unique visitors to the VIMM website
What’s Next?
Use the VIMM as a model for other Internet2 events
