Preparing for WTSAIssues on SG Structure

  Gary Fishman

ITU-T TSAG Chairman

Preparatory Meeting for Africa for WTSA-04

Victoria Falls, 23-25 June 2004


What is the issue l.jpg
What is the issue?

  • 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?

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


What work should be done in itu t l.jpg
What work should be done in ITU-T?

  • 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

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


How should this work be organized l.jpg
How should this work be organized?

  • Related Blocks are being associated into about 15-20 Functional Groupings. For example:

    • Performance FG = Block 12A (all of SG12) + Block 13A (WP4/13)

    • EMI = Block 5A (all of SG5)

What are the objectives for restructuring the sgs l.jpg
What are the objectives for restructuring the SGs

  • Efficiency, relevance, clear mandates

  • Visibility to outside world

  • Many different views and objectives have been introduced by the membership

  • See recent report on restructuring work in TSAG TD/340 Rev.1

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Itu t should have a strong presence in certain areas l.jpg
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.

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


What seems to be nearly agreed l.jpg
What seems to be nearly agreed?

  • Continue the SG as is

    • SG3 – Tariff and accounting principles

    • SG5 – Electromagnetic compatibility

    • SG6 – Outside plant

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


What seems to be nearly agreed8 l.jpg
What seems to be nearly agreed?

  • Core work of a SG to continue, with possible additions

    • SG4 – Network management

    • SG12 – End-to-end performance

    • SG15 – Transmission systems

    • SG16 – Multimedia

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


What seems to be nearly agreed9 l.jpg
What seems to be nearly agreed?

  • Other SGs that are being treated as Blocks

    • SG11 – Signalling

    • SSG – IMT-2000 and beyond

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Trends in functional groupings l.jpg
Trends in Functional Groupings

  • Consolidate Network Operations: combine WP2/2 and Network Management (SG4)

  • Consolidate Performance: combine WP4/13 and SG12

  • Build an NGN SG: discussion continues on what and how much to include

  • Build a Security SG

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


But to make it interesting l.jpg
BUT – to make it interesting

  • Two approaches: Change for change sake vs. If it ain’t broke, don’t fix it

  • Balance between: massive consolidation into a few large Study Groups vs. Study Groups based on specific topics and expertise

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Some issues to be resolved l.jpg
Some issues to be resolved

  • 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?

  • Signalling – a SG or part of another SG?

  • Keep a Mobility SG (SSG) or merge with other work?

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Some issues to be resolved13 l.jpg
Some issues to be resolved

  • What goes into the NGN Study Group?

  • What goes into the Security Study Group?

  • Numerous details of work allocation among 150+ study questions

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Considerations l.jpg
Considerations

  • Some consolidation of work will help

    • Avoid divergent solutions

    • Share time of experts among study items

    • Reduce need for liaisons

  • Too much consolidation of work will hurt

    • Less time per study item during meeting

    • Parallel meetings cannot be covered by experts

    • External liaison relationships become less clear

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Consequences or why do we care l.jpg
Consequences...orWhy do we care?

  • Make ITU-T THE most attractive place to do international standards

  • Make best use of experts’ time and resources

  • Avoid duplication and overlap of work

  • Lower costs to membership and to ITU

  • A bad structure will slow down or stop work; a good structure can speed up work

WTSA Preparatory Group for Africa Victoria Falls 23-25 June 2004


Maintaining future relevance l.jpg
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

  • WTSA Resolution 22 gives TSAG authority to change study group structure between WTSAs and to create groups with short life-times
