2 Overview of TF-VSS NIIF – http://www.niif.hu 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

3 Status of TF-VSS activities NIIF – http://www.niif.hu ActivityScheduleTitleLeader A1Start: 01/10/06 End: 06/10/06 Setting up taskforce…András Kovács (NIIF/HUNGARNE T) A2Start: 01/10/06 End: 31/10/06 Survey on future plans and EU VC service (D2.1) András Kovács (NIIF/HUNGARNE T) A3Start: 01/11/06 End: 30/11/06 Service specification (D3.1)John S.

4 Activity A2 NIIF – http://www.niif.hu 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

5 Activity A3 / GN2 proposal I. NIIF – http://www.niif.hu Service specification: D3.1 is available Basic (1 st phase) and advanced (2 nd phase) service Pros & cons of central and shared implementations CentralShared Standards based (H.323 and SIP) + multipoint (MCU) service Central MCU resourceBased on NRENs’ spare capacities, heterog. equipments Easy multiprotocol (H.323/SIP) operationDifficult multiprotocol operation Shared support on a single deviceShared support on multiple devices (SLA?) Easy prioritizationCannot prioritize national vs. external claims Easy to introduce new features (e.g. HD)Difficult to introduce new features Easy implementation of gatewaysDifficult (distributed) implementation of gateways Easy monitoring, management & reportingDistributed monitoring, management & reporting -Interdomain provisioning protocol must be designed Can be resilient and scalable (more expensive)Resilient and scalable High quality serviceQuality? Expensive (200-250kEuro)Cheap, but requires 2-3x more human resources

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

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

8 Activity A3 / GN2 proposal II. NIIF – http://www.niif.hu 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...

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

10 European level VC support NIIF – http://www.niif.hu 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…

11 GN2 Y4 proposal III. NIIF – http://www.niif.hu Preliminary proposal: Presented at GN2 Y4 planning meeting (2 nd 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 ResourceCentralShared Manpower requirement28MM38MM Operation cost per year12MM24MM Equipment budget150kEuro (MCU)servers

12 GN2 Y4 proposal IV. NIIF – http://www.niif.hu 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

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