1. TF-VSS’s proposal of a European-wide videoconferencing service

2. Outline Videoconferencing basics Need for a European-wide effort Proposal from TF-VSS

3. Videoconferencing basics End point End point End point End point MCU gatekeeper IP address

4. Current status National deployments –MCU –GDS Gatekeepers; world hierarchy GDS, developed as a temporary solution, is being used in production –Otherwise, need IP address book –Lately, efforts towards transitioning to ENUM; but this is still being researched –Best effort support

5. Current status – TF-VSS survey http://www.terena.org/activities/tf-vss/tf_vss_survey_v1.0.pdf User scheduling Multi-point videoconferences NRENEnd User

6. Usefulness of a EU-wide service http://www.terena.org/activities/tf-vss/tf_vss_survey_v1.0.pdf

7. TF-VSS proposal Complementary, not competing with national deployments ! Motivation Target users What Whom When Costs

8. Motivation can improve collaboration at a higher level some NRENs would give up building national services (MCU) at a low utilisation could open new avenues in collaboration in Europe and possibly beyond that.

9. Target users the whole academic community, all the constituency of European NRENs NRENs without a national service less developed European NRENs' user community, fighting the digital divide

10. What – coordination of support Replace the ad-hoc coordination with a consistent framework for supporting VC throughout Europe Coordinate GDS support Troubleshooting Ticket system –Based on existing GN2 tools Monitoring and Diagnosing –Based on adding functionality to standard GN2 tools

11. What - equipment Central MCU –Small size – 40 ports –Support for H.323, SIP and perhaps HD PC Server –Gatekeeper –Monitoring system –Central VC directory (portal) –Calendar and Reservation system Open issue: where the install ? Geant2 PoP ?

12. Costs – how much ? Procurement, deployment and capacity planning: 8MM Establishing a central reservation website with federative authentication: 6MM Implementation of a modular reservation system: 8 MM Operational model and monitoring: 6 MM 1 MY for service support (one person, full time) Hardware cost estimate: –MCU: 150000 euro –Server: 4000 euro

13. Whom - participants Small amounts of manpower could be made available by the following NRENs (for now): CESNET CSC GRNET NIIF/HUNGARNET REDIRIS SWITCH

14. When - timeline start Oct 2007 Pilot running by Oct 2008

15. Summary of benefits
