21 September 2005

Agenda

• Current situation in standards

• The shape of the standards world

• BT’s 21st Century Network (NGN)

• What are the important standards bodies for the NGN?

• Problems with way standards are developed

• Ways forward to solve problems

• Conclusions

What is the Current situation in Standards?

• Multiple networks exaggerate the cost of multiple standards.

• Cost of interworking is high.

• All telcos under pressure to reduce expense on standards

• Growing complexity from multiple fora

• More and more uses are global (mobile, WLAN, Internet etc) with more and more users travelling.

• Need for a radical drive to the NGN – speed is essential.

• Standards must be global

21C aims

• Revolutionise customer experience– Make it easier to buy and use services

– Enable customers

• Deliver innovative products more rapidly– Rapid service creation & implementation

– With more people creating new services

• Make it simpler to deliver and maintain service– Process, systems & network automation

• Transform the cost base of the Company– Enabler of whole life cost reduction (CAPEX & OPEX)

Why standards…

• To enable new services– must operate on global basis

• To reduce costs– commoditisation of equipment

• To meet regulatory requirements– essential interfaces

• To ensure accessibility/safety/security, etc

Highest Priority 21C Standards Requirements

• Multi-service carrier-scale core– enabled by underlying ‘MPLSv2’ network

• Mobility enabled intelligence– Extending the IMS to Wi-Fi and fixed Broadband access

• PSTN replacement– H248/IP network able to provide telephony features

• Session based QoS

• Session Control– extensions to SIP with full multimedia capability

• Billing and charging (data interchange billing) between operators

• Manageability– commoditised componentised OSS

• Security– authentication across networks / operators

• Home Gateways/Networks

Important Standards Bodies for 21CN• ETSI – TISPAN and 3GPP

• ITU – Global standards

• ATIS – US standards priorities

• IETF – IPv6, SIP extensions, MPLS, etc

• TMF, with OSS/J – standardised OSS components

• MSF – Interoperability of VoIP elements of NGN

• Open Mobile Alliance (OMA), with Parlay – (Mobile) Applications, DRM

• Metro Ethernet Forum (MEF) – role of Ethernet in transport network

• DSL forum, DSL and QoS architectures

• IEEE 802.11x – Wi-Fi hotspots

• W3C – Privacy, Web Services

• WiMAX forum

Problems…

• Plethora of Standards Bodies and Fora

• Service Providers don’t have enough influence over standards

• The IETF doesn’t work anymore

• The IPR morass

There are so many standards bodies out there

• CEN/ISSS Consortia Survey– www.cenorm.be/isss

• ETSI FORAwatch– www.etsi.org/forawatch

• Over 500 standards bodies and fora listed

Service Providers don’t have enough influence

• SPs used to drive formal standards

• Economic downturn caused SPs to withdraw from standards

• Competitors not collaborators

• IETF working to different business model

IETF doesn’t work anymore

• Developing standards in best interests of the Internet

"The purpose of the IETF is to create high quality, relevant, and

timely standards for the Internet.”

• Dominated by vendors

• Doesn’t listen to Service Providers

The IPR Morass

• Most bodies adopt RAND (or FRAND) policy

• RF is a special case of RAND

• What is “fair and reasonable”?

• What is “essential”?

• What is a late declaration?

• Problem of ambushing (or submarining)

So how can we get the Standards we need to build NGNs?

• Coordinate existing bodies better

• Use formal and informal standards bodies appropriately

• Use bodies such as ATIS to promote needed standards

• Create Service Provider Requirements fora

• Promote fora specifications to formal standards

• Harness the IETF

• Encourage Royalty Free IPR policies

Examples of good coordination

• ICT Standards Board

• Informal Forums Summit

• ISO/IEC/ITU MoU on eCommerce

• Multi-Service Forum (MSF)

ICT Standards Board

• ANEC

• ATM Forum

• CEN

• CENELEC

• DVB

• EBU

• ECBS

• Ecma International

• EFTA Secretariat

• EICTA

• ERTICO

• ETSI

• European Commission

• ISOC (IETF)

• Liberty Alliance

• NORMAPME

• OASIS

• OMA

• OMG

• OSGi

• RosettaNet

• The Open Group

• TMF

• W3C

Why ICTSB?

• Reaction to convergence of information technology, telecommunications, broadcasting and entertainment industries

• Need to reduce overlaps between activities of European Standards Organisations (ESOs)

• Need to involve (many) fora and consortia

• Provide European focus for Global ICT Standardization

What does ICTSB do?

• Analyses requirements from any competent source based on concrete market needs

• Translates these requirements into coherent standards work programmes

• Allocates work items to members and reviews progress against objectives

ICTSB (and WGs) does not produce standards

ICTSFG Report – April 2005

• Structure and organization of ICT standardization at global, regional and national level

• Role of public authorities in ICT standardization, including Government as regulator, enforcer and major procurer

• Economics of ICT standardization, including educational, promotional and awareness issues

• Role of end-users

4 Streams

Relationship between formal and informal bodies

• Fora / consortia should develop more systematic relationships with formal standards bodies

• Formal standards bodies should adopt more pro-active approach towards consortia

• Global consortia should take account of regional dimension

• Co-ordination between consortia and formal SDOs should be improved by encouraging development of issue-specific coordinating bodies

Promoting Forum Specifications to Formal Standards

Examples of successful processes:

• European DVB agreement with ETSI

• Fast track and PAS procedures in ISO/IEC JTC1

• Focus Group (A.7) procedure in ITU-T

Service Provider Requirements groups

• e.g. MPLS & Frame Relay Alliance (MFA)

• FSAN VDSL

• IPsphere is considering– WG Chair model instead?

• Service Providers only?

• Must have formal route into other WGs

• Must not be at expense of Board positions

What to do about IPR?

• Insistence on RF doesn’t work– companies do it outside

• Insist on early declaration

• Encourage RF where possible– e.g. CEN/CENELEC IPR policy:

“If in exceptional cases, technical reasons justify the preparation of a European Standard in terms which include the use of a patented item, there is no objection in principle to such a step, even if the terms are such that there are no alternative means of compliance”

Conclusions

• NGN will only succeed based on globally standardised components

• Standards bodies need to collaborate between fora, regional and global standards bodies

• We should only write the standard once and end point should be global standard in the ITU

• Everyone wins:– vendors

– operators

– users
