  2. Agenda • Virtual Internet2 Member Meeting (VIMM) • Internet2 Commons • Monthly Virtual Briefings

  3. Virtual Internet2 Member Meeting

  4. 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

  5. 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>

  6. 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

  9. 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

  10. 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

  11. What’s Next? • Use the VIMM as a model for other Internet2 events • Seek out other content • Internet2 Monthly Virtual Briefings • “Powered by the Commons” • 90 minute sessions with speakers and audience (across up to five time zones)

  12. What’s Next, Cont. • Developing “director’s studio” for managing events, with plans for scheduled hands-off access • Features will include “protocol-agnostic MCU”, titling, gateways, archiving, transcoding, …

  13. Internet2 Commons

  14. The Internet2 Commons • An effort to encourage and support large-scale, distributed collaboration for the research and education community • Enabling one-to-one, one-to-group, and group-to-group collaboration • Supporting personal communications, meetings, conferences, and teaching and learning • For Internet2 members and their international partners

  15. Other Collaborative Technologies The Internet2 Commons Commons Vision Voice/IP Peer to Peer Collaboratories H.323 Electronic Notebooks Data Sharing Instant Messaging Others VRVS AG MPEG2 Others Videoconferencing Technologies

  16. Status • H.323 service in initial deployment phase • MCU capacity donated by Accord and Radvision located at OSU/OARnet and available for scheduled/unscheduled use • Streaming available via Starbak servers • Approximately 45 Commons Site Coordinators confirmed or being confirmed

  17. Status, cont. • R&D efforts continue • DVTS over IPv6 (demo at Spring Internet2 meeting) • MJPEG within Access Grid • Measurement and monitoring tools • Planning evaluations of SIP VC technologies • …

  18. Next Steps • Seeking content sources • Phase II Requirements Gathering • Move beyond H.323 in production core • Expand technology explorations • Include other collaboration tools • Define “value add” in services offering • Will share initial report at Internet2 MM, final report due in June

  19. Monthly Briefings

  20. Monthly Briefings: Goals • Share progress of Internet2 initiatives • Find the optimal mix of quality, audience reach, and interactivity • Provide production service while experimenting with new technologies

  21. Monthly Briefings: Technology • Real, Windows, and/or QuickTime streams (typically 384-512 kbps) • IP/TV (1.5 mbps) • VRVS (varies) • H.323 (384-768 kbps) • MPEG-2 (7-15 mbps) • MJPEG/RTPtv (10-15 mbps) • Access Grid (varies)

  22. Monthly Briefings: Issues • Integrating technologies without resorting to lowest common denominator • Authentication and authorization aren’t addressed • End-to-end performance • Production values • Floor control
