  importance
• May be shared within several SGs
• May correspond to (very) urgent market needs
• Needs for coordination
• May be used to clarify areas for study

ITU-T IP Project
ITU-T and IETF Collaboration must be strengthened
considering interest in ITU-T on IP-based
networks IETF and ITU-T are not able to
adequately address this area independently IETF
strength protocol and application areas ITU-T
great experience in the areas of architecture,
network interworking and network evolution

• Explosive growth of the Internet/IP-based
  networks
• Ever increasing demand for higher
  bandwidth/capacity
• Network operators, service providers and
  manufacturers reconsider services, network
  structures, products etc
• IT and use of IP-based networks and applications
  (e.g. e-commerce) become critical factors in
  development of telecom networks

5
ITU-T IP Project

• Since 1998, the IP project is updated by the SG
  13 Project Leader taking into consideration major
  deliverables from the various Study Groups, i.e
  Recommendations approved or planned (before 1998,
  IP was a sub-project of the ITU-T GII project)
• Y.1000 to Y.9999 reserved for IP-related
  Recommendations.
• For each area, the IP Project identifies
• scope and focus of the work area
• issues for consideration
• status of current work within ITU-T
• related work within IETF
• Edition 5 SG 13 meeting, 14-25 May 2001 (ITU-T
  Website)

Access Network Transport

• Q.1/15
• Access Network Transport Standardization Plan,
  issue 4 (Feb. 2001)
• Access Network Transport Work Plan, issue 3 (Feb.
  2001)

11
The ANT standardization plan

• Identifies
• Existing standards
• Topics/standards under development
• Lack of standards
• Possible duplication and/or overlap
• Market needs
• Priorities

12
The ANT work plan

• facilitates coordination/negotiation for
  additional work on ANT (who, when, where, etc.)
• provides overview of ongoing ANT activities
• revises ANT standardization plan as required
• monitors progress of ANT standards work

13
ANT reference scenarios for correlation of
standards

• The scenarios are intended to
• Facilitate identification of key reference points
  in a scenario
• Facilitate classification of interfaces
• Facilitate identification of services that can be
  carried across interfaces
• Facilitate classification of services
• Facilitate identification of end-points for
  service delivery

14
ANT reference scenarios for correlation of
standards

• Facilitate investigation of interaction between
  all components
• Facilitate identification of access network
  transport technologies
• Be generic enough to facilitate scenario
  development across all technologies and Standards
  Development Organizations (SDOs) areas
