1. ATU-ITU|TATU-ITU|T Preparing for WTSA Issues on SG Structure Gary Fishman ITU-T TSAG Chairman Preparatory Meeting for Africa for WTSA-04 Victoria Falls, 23-25 June 2004

2. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 2 What work should be done in ITU-T? How should this work be organized? What are the objectives for restructuring the Study Groups (SGs)? How will SG structure stay relevant? What is the issue?

3. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 3 TSAG examined the work of all the SGs and work for the future Identified about 40 Blocks of work that should be treated as indivisible units. For example: Block 3A: tariff & accounting principles Block 5A: EMI Block 13B: architecture, interworking and multi-protocol networks except Ethernet What work should be done in ITU-T?

4. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 4 How should this work be organized? Related Blocks are being associated into about 15-20 Functional Groupings. For example: Related Blocks are being associated into about 15-20 Functional Groupings. For example: Performance FG = Block 12A (all of SG12) + Block 13A (WP4/13) Performance FG = Block 12A (all of SG12) + Block 13A (WP4/13) EMI = Block 5A (all of SG5) EMI = Block 5A (all of SG5)

5. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 5 What are the objectives for restructuring the SGs Efficiency, relevance, clear mandates Efficiency, relevance, clear mandates Visibility to outside world Visibility to outside world Many different views and objectives have been introduced by the membership Many different views and objectives have been introduced by the membership See recent report on restructuring work in TSAG TD/340 Rev.1 See recent report on restructuring work in TSAG TD/340 Rev.1

6. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 6 ITU-T should have a strong presence in certain areas Critical areas for future work must include: Next Generation Network (NGN) Security Mobility E-Everything Network infrastructure: Optical Transport, IP- based Networks, Network Management, Signalling, Performance, EMC, Architecture, Interoperability, etc.

7. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 7 What seems to be nearly agreed? Continue the SG as is Continue the SG as is SG3 – Tariff and accounting principles SG3 – Tariff and accounting principles SG5 – Electromagnetic compatibility SG5 – Electromagnetic compatibility SG6 – Outside plant SG6 – Outside plant

8. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 8 What seems to be nearly agreed? Core work of a SG to continue, with possible additions Core work of a SG to continue, with possible additions SG4 – Network management SG4 – Network management SG12 – End-to-end performance SG12 – End-to-end performance SG15 – Transmission systems SG15 – Transmission systems SG16 – Multimedia SG16 – Multimedia

9. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 9 What seems to be nearly agreed? Other SGs that are being treated as Blocks Other SGs that are being treated as Blocks SG11 – Signalling SG11 – Signalling SSG – IMT-2000 and beyond SSG – IMT-2000 and beyond

10. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 10 Trends in Functional Groupings Consolidate Network Operations: combine WP2/2 and Network Management (SG4) Consolidate Network Operations: combine WP2/2 and Network Management (SG4) Consolidate Performance: combine WP4/13 and SG12 Consolidate Performance: combine WP4/13 and SG12 Build an NGN SG: discussion continues on what and how much to include Build an NGN SG: discussion continues on what and how much to include Build a Security SG Build a Security SG

11. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 11 BUT – to make it interesting Two approaches: Change for change sake vs. If it aint broke, dont fix it Two approaches: Change for change sake vs. If it aint broke, dont fix it Balance between: massive consolidation into a few large Study Groups vs. Study Groups based on specific topics and expertise Balance between: massive consolidation into a few large Study Groups vs. Study Groups based on specific topics and expertise

12. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 12 Some issues to be resolved Numbering, Naming, Addressing, Routing: Block 2A (mostly the current WP1/2) – where to place? Numbering, Naming, Addressing, Routing: Block 2A (mostly the current WP1/2) – where to place? Keep Cable Broadcast together (SG9), make small modifications or split it up completely? Keep Cable Broadcast together (SG9), make small modifications or split it up completely? Signalling – a SG or part of another SG? Signalling – a SG or part of another SG? Keep a Mobility SG (SSG) or merge with other work? Keep a Mobility SG (SSG) or merge with other work?

13. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 13 Some issues to be resolved What goes into the NGN Study Group? What goes into the NGN Study Group? What goes into the Security Study Group? What goes into the Security Study Group? Numerous details of work allocation among 150+ study questions Numerous details of work allocation among 150+ study questions

14. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 14 Considerations Some consolidation of work will help Some consolidation of work will help Avoid divergent solutions Avoid divergent solutions Share time of experts among study items Share time of experts among study items Reduce need for liaisons Reduce need for liaisons Too much consolidation of work will hurt Too much consolidation of work will hurt Less time per study item during meeting Less time per study item during meeting Parallel meetings cannot be covered by experts Parallel meetings cannot be covered by experts External liaison relationships become less clear External liaison relationships become less clear

15. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 15 Consequences...or Why do we care? Make ITU-T THE most attractive place to do international standards Make ITU-T THE most attractive place to do international standards Make best use of experts time and resources Make best use of experts time and resources Avoid duplication and overlap of work Avoid duplication and overlap of work Lower costs to membership and to ITU Lower costs to membership and to ITU A bad structure will slow down or stop work; a good structure can speed up work A bad structure will slow down or stop work; a good structure can speed up work

16. ATU-ITU|TATU-ITU|T WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004 16 Maintaining Future Relevance TSAG is responsible to review progress of the work programme, the allocation of work among ITU-T SGs and between ITU-T and ITU-R TSAG is responsible to review progress of the work programme, the allocation of work among ITU-T SGs and between ITU-T and ITU-R WTSA Resolution 22 gives TSAG authority to change study group structure between WTSAs and to create groups with short life- times WTSA Resolution 22 gives TSAG authority to change study group structure between WTSAs and to create groups with short life- times
