industry?

1. ITU-T – The Organization

4eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Structure of ITU: 3 Sectors

1. ITU-D: aid to developing countries2. ITU-R: radio spectrum & satellite slot

allocations3. ITU-T: standardization (this talk)

• Telecom network: arguably one of mankind’s most complex projects

• ITU-T made the necessary standards

o ITU Secretariat: based in Genevao ITU = UN agency

5eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Who comprises ITU/ITU-T?o ITU: Member States (189 countries)o ITU-T: Sector Members = private

sector• Operators & manufacturers• From start-ups to big companies• Telecom and Computing

o ITU-T Product: Recommendations (ITU-T speak for “standards”)

o Work is done by Member States & Sector Members:

• 95% of work is done by private sector• Member States: if regulatory impact

ITU-T has changed dramatically in last years

o ITU-T is fast to• start work: 1 day / few weeks (from 2-4 yrs)• develop work: weeks to 2-3 yrs (from 2-3

yrs)• approve work: 2 months (from 4 yrs)

• “Speedy Gonzalez approval procedure” for technical standards (=95% of work)

• publish work: couple of days after approval (from 2-4 yrs)

o ITU-T standardizes hot topicso ITU-T is very flexible & unbureaucratic

7eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Flexible collaboration: ITU-T Focus Group Concept

o Create forum-like entities as an “arms-length” organization under ITU-T Study Group

o Goal:• Encourage participation of members

of other organizations / non-members

o Very flexible, e.g.• Focus group can establish its own

rules of approval

8eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Strengths of ITU-To Unique partnership of industry &

governmento Truly globalo Consensus decisions guarantee wide

acceptanceo Excellent, transparent, fast procedureso Very flexible to collaborate with fora and

standards organizationso Excellent networking opportunitieso Brand nameo IPR Policyo World-class meeting facilitieso Excellent Secretariat staff

2. ITU-T – The Work & Services

10eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Making Standards: Recent highlights

o Quadrupling fibre optic transmission capacity (10 Gbit/s to 40 Gib/s): ITU-T Rec. G.959.1

o Fat pipes get fatter through Coarse Wave Division Multiplexing (ITU-T Rec. G.695)

o Novel video coding algorithm (with ISO/IEC) - expected to be deployed in all future DVD players, 3G phones and video-conferencing equipment (ITU-T Rec.H.264)

o Opening up world for interactive TV providers (ITU-T Rec. J.202)

11eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

ITU-T Study Groups

o SG 2 Operational aspects of service provision, networks and performance

o SG 3 Tariff and accounting principles including related telecommunications economic and

policy issues o SG 4 Telecommunication management, including TMN o SG 5 Protection against electromagnetic environment effects o SG 6 Outside plant o SG 9 Integrated broadband cable networks and television and sound

transmission   o SG 11 Signalling requirements and protocols o SG 12 End-to-end transmission performance of networks and terminals o SG 13 Multi-protocol and IP-based networks and their internetworking o SG 15 Optical and other transport networks o SG 16 Multimedia services, systems and terminals o SG17 Data networks and software for Telecommunicationo SSG Special Study Group "IMT-2000 and beyond" o TSAG Telecommunication Standardization Advisory Group

12eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Further ITU-T Services

o Management of numbering resources

o Organization of workshops:• Convergent regulation – is it

becoming technology-neutral?, 17 May 04

• All Star network access, 2-4 June 04• Home networking and home

services, 16-18 June 04

13eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

3. How ITU-T can help the Grid industry

14eInfrastructures Open Workshop (Internet & Grids), 15 April 2004

Possible steps forward

o Grid-community to give talks at ITU-T standards meetings (mostly in Geneva) – and vice versa

• Has already been startedo ITU-T Workshop on Grids with focus

on interaction Grid & telecom industry

o Focus group concept: very flexible way to form partnerships
