  1. Issues, working methods and collaboration B. Georges Sebek ITU/TSB Engineer

  2. Main issues covered by ITU-T • IP-related issues, IMT-2000, accounting rates • ITU-T IP Project • IPCablecom Project • Multimedia, access network (e.g. xDSL), security, numbering and addressing, inter-operability, languages, TMN, IPR, etc. • Mediacom 2004 Project • ANT • ENUM • ASN.1 Project • OTN • NGN • Performance & QoS ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  3. What 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 ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  4. 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 ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  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 variousStudy Groups, i.e Recommendations approved or planned (before 1998, IP was a sub-project of the ITU-T GII project) • Y.1000to 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, 14-25May 2001 (ITU-T Website) ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  6. ITU-T IP Project • Area 1- Integrated architecture • Area 2 -Impact to telecommunications access infrastructures of access to IP applications • Area 3 -Interworking between IP-based network and switched-circuit networks, including wireless-based networks • Area 4- Multimedia applications over IP • Area 5 -Numbering and addressing • Area 6 -Transport for IP-structured signals • Area 7 -Signalling support, IN and routing for services on IP-based networks ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  10. Access Network Transport • Q.1/15 • Access Network Transport Standardization Plan, issue 4 (Feb. 2001) • Access Network Transport Work Plan, issue 3 (Feb. 2001) ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  11. The ANT standardization plan Identifies • Existing standards • Topics/standards under development • Lack of standards • Possible duplication and/or overlap • Market needs • Priorities ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  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 ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  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 ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001

  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 ITU-T and ITU-D Workshop - Bangalore (India), 30-31 August 2001
