The Paramount Importance of Standards to Operators, Vendors and Users Keith Dickerson BT Group Technology Office 21 September 2005

Agenda Current situation in standards The shape of the standards world BT’s 21 st 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 x – 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 – ETSI FORAwatch – Over 500 standards bodies and fora listed

Standards “Food Chain”

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
