3What are ITU-T Projects?
- Standardization domain identified as of
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
4ITU-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
5ITU-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)

Recommendations
10Access Network Transport
- Q.1/15
- Access Network Transport Standardization Plan,
issue 4 (Feb. 2001) - Access Network Transport Work Plan, issue 3 (Feb.
2001)
11The ANT standardization plan
- Identifies
- Existing standards
- Topics/standards under development
- Lack of standards
- Possible duplication and/or overlap
- Market needs
- Priorities
12The 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
13ANT 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
14ANT 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
