  11. Highlights of achievements (I) Data Networks • Revised core PDN Recommendations to take into account deployment of frame relay networks (F.600, X.7) • Updated basic frame relay interface Recommendations (Q.933, X.36, X.76) • Developed new Recommendation specifying support of frame relay services over MPLS core networks (X.84) • Developed new and revised Recommendations on QoS and O&M for frame relay networks (X.142, X.144, X.145, X.147, X.148, X.149, X.151)

  12. Highlights of achievements (II) Data Networks (continued) • Maintained and developed new Recommendations related to numbering and routing, taking into account interworking with ATM or IP-based networks (X.110, X.111, X.213) • Specified protocols and service mechanisms for multi service data networks (X.85, X.86, X.87) • Updated publicly available basic information on the SG 17 web page • Worked closely with related fora and consortia (IETF, MPLS/Frame Relay Alliance)

  13. Highlights of achievements (III) Collaborative work with ISO/IEC JTC 1/SC 6 on: Multicast • 4 Recommendations were completed on multicast communications service with QoS control capacity (X.602, X.603, X.606, X.606.1) Directory • 4th edition of the X.500-series was completed with additional specification for privilege management infrastructure (PMI)

  14. Highlights of achievements (IV) Security Developed 5 core security Recommendations • X.805, Architecture for providing end-to-end network security • X.1051, Information security management system • X.1081, Telebiometrics • X.1121, Security in a mobile environment • X.1122, Constructing secure mobile systems based on PKI

  15. Highlights of achievements (V) Security Project • Organized security workshop, May 2002 • Developed web page with latest security information • compendium of ITU-T security Recommendations • compendium of security definitions from approved Recommendations • Contributed to the ITU-T ‘Security Manual’ • Established coordination with other Study Groups (security coordinators) and with other SDOs • Strengthened collaborative work with ISO/IEC

  16. Highlights of achievements (VI) Languages and telecommunication software • ASN.1 – Abstract Syntax Notation One • SDL – Specification and Description Language • MSC – Message Sequence Charts • URN – User Requirements Notation • UML – Unified Modelling Language • TTCN – Testing and Test Control Notation • ODL – Object Definition Language • ODP – Open Distributed Processing

  17. Highlights of achievements (VII) Languages and telecommunication software • Complete revision of suite of 8 Recommendations for ASN.1, and is highly used in other Recommendations. Work on Fast Web Services and Fast Infoset started and almost completed. The ASN.1 module database and OID database is a major achievement. • For SDL, the Formal Definition was completely revised, and a new edition of SDL issued in 2002. There has been considerable influence by SDL and MSC on the new OMG UML 2.0 standard.

  18. Highlights of achievements (VIII) Languages and telecommunication software • A new Recommendation on URN (User Requirements Notation – Z.150) was issued. • A major breakthough was the new testing language TTCN in co-operation with ETSI, which goes far beyond conformance testing only, e.g. including the important are of interoperability. • A Recommendation Z.450 was issued on "Quality Aspects of Protocol-related Recommendations", earlier part of the A Series of Recommendation

  19. Workshops (I) Organized by SG 17 • Use of Formal Languages,Geneva, 19 July 2004 • Use of UML for ODP and ITU-T languages,Geneva, 14 March 2004 • Integrated Application of Formal Languages,Geneva, 13 September 2003 • Language Advisory Board,Geneva, 24 November 2002 • Use of Description Techniques,Geneva, 23 November 2002

  20. Workshops (II) Organized by SG 17 (or 7 or 10) • Security,Seoul, 13-14 May 2002 • Framework and scope of formal languages, Geneva, 2 March 2002 • ITU-T and ITU-D Sectors Joint Workshop Bangalore, 31 August 2001 • Philosophy and applicability of formal languagesGeneva, 15 September 2001 • Software for telecommunications,Moscow, 20 July 2001

  22. Future Work (I) Frame Relay and Data communication • Interworking of frame relay with MPLS, ATM & Ethernet networks, incl. QoS and O&M • Multi-service data networks at layer 2 • 5th edition of the Directory (X.500-series) • Multicast communications (duplex, N-plex) with managed QoS

  23. Future Work (II) Telecommunication security • New core Recommendations on security architecture, frameworks, mechanisms and procedures • Address security threats, security vulnerabilities and risk assessment as well as associated issues on privacy • Systematic approach to cover full range of prevention / protection, detection, response, containment, restoration/recovery and forensics / attribution • Further develop awareness (web, 2nd Security Workshop early next study period)

  24. Future Work (III) Languages and Telecommunication software • Strengthening the position of ITU-T language family (ASN.1, SDL, MSC and TTCN) • For ASN.1 complete work on Fast Web Services and Fast Infoset. Expand the ASN.1 database and object identifier database to support web services • For SDL and MSC, focus on simplification of the languages and on UML profiles • TTCN will progress in collaboration with ETSI • New languages, eODL and URN would be advanced to a mature stage

  25. Acknowledgements • Great thanks are given to the SG 17 participants, editors, rapporteurs and the leadership team whose important contributions resulted in the successful results reported here • Special thanks are due to G. Sebek, G. Regan, N. Joubert and the rest of the TSB staff for their outstanding support and guidance. • It is with deep sadness that we learned this year of the death of Mr. Ossipov (Russia), a vice-chairman of SG 17 and formerly of SG 7, who so ably guided our work on public data network services
