agenda
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
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
21C aims

why standards
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
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
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
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

Access Network Standards
service providers don t have enough influence
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
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
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
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

ICT Standards Board
why ictsb
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
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
ICTSFG Report – April 2005

4 Streams

  • 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
relationship between formal and informal bodies
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
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
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
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
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
