  2. Overview of TF-VSS • TF-VSS: Videoconference Service Studies group • Mandate: 01/10/2006 – 30/09/2007 • Preliminary support for a European VC service: • Gather needs and general views • Prepare a specification (recommendation) • High level technical plans • GN2 Y4 proposal preparation • Feasibility study • Reminder: • GN2 Y3 → failed • Technical complexity, lack of motivation NIIF– http://www.niif.hu

  3. Status of TF-VSS activities NIIF– http://www.niif.hu

  4. Activity A2 • Web survey: • NREN/institutional VC deployments and mid-term plans • Approach to a European VC service • D2.1 available at TF activities’ page: • http://www.terena.org/activities/tf-vss/activity_areas.html • Responders: 19 European NRENs and 11 large institutions NIIF– http://www.niif.hu

  5. Activity A3 / GN2 proposal I. • Service specification: D3.1 is available • Basic (1st phase) and advanced (2nd phase) service • Pros & cons of central and shared implementations NIIF– http://www.niif.hu

  6. Architecture: central resource NIIF– http://www.niif.hu

  7. Architecture: shared resource NIIF– http://www.niif.hu

  8. Activity A3 / GN2 proposal II. • For both implementations: • Free gatekeeper (H.323) and registrar (SIP) services • Central reservation website (localised) • Federated AAI • Federated European-scale directory • Standardised video codecs: H.261, H.263 and H.264 • Gateways (e.g. ISDN, VRVS/EVO, etc.) • Data collaboration • API based MCU control • . . . NIIF– http://www.niif.hu

  9. Federated directory NIIF– http://www.niif.hu

  10. European level VC support • Implementation of support: • Hierarchical (European, national, institutional level) • NRENs: round robin basis (see e.g. GN2 PERT) • Important: GDS, coordinating between NREN support groups • Operational model to be worked out… NIIF– http://www.niif.hu

  11. GN2 Y4 proposal III. • Preliminary proposal: • Presented at GN2 Y4 planning meeting (2nd April) • Draft work items specified • Option A (shared) and option B (central): • Partners: CESNET, CSC, GRNET, NIIF, • REDIRIS, SWITCH (informal survey) • Manpower bids: 6MM • Very low/limited motivation and contribution NIIF– http://www.niif.hu

  12. GN2 Y4 proposal IV. • Proposal refinement: • In progress… based on feedback (GN2) • Central resource was chosen (human resources) • Budget: 200-250kEuro (vendor offers) • Work items finalised • Available for contribution and comments/ideas • Reduce complexity, and minimise human resource needs • Decision should be taken: continue or not • Provide official feedback: • Work item participation • Manpower bids NIIF– http://www.niif.hu

  13. GN2 Y4 proposal V. - Options • Options to chose: • Proposal as it is… (+MCU, +support, +reservation, +dir, …) • Reduced 1 (-MCU, +support, -reservation, +dir, …) • Cancel proposal • . . . NIIF– http://www.niif.hu
