1 ITU-T Study Group 13 Structure and Responsibilities Brian Moore Study Group 13 Chairman Lucent Technologies

2 Outline Study Group 13 mandate and work plan Study Group 13 structure Lead Study Group activities –GII –IP –SAT ICG Future activities

3 Study Group 13 mandate Multi-protocol and IP-based networks and their internetworking Responsible for studies relating to internetworking of heterogeneous networks encompassing multiple domains, multiple protocols and innovative technologies with a goal to deliver high-quality, reliable networking. Specific aspects are architecture, interworking and adaptation, end-to- end considerations, routing and requirements for transport.

4 Mission To provide a focal point in ITU for technology-independent network architecture and long-term evolution studies, including IP-network studies, through development of the necessary frameworks and architectures, coordination with the various related studies in the other ITU Study Groups and collaboration with other standards bodies.

5 To help ITU-T continue to respond to the changes to studies and priorities necessary to integrate traditional telecommunication networks with IP-based networks in order to provide full integration of services and applications to end users. Also, to give network providers the tools and information to support the market-driven changes to the telecommunication industry.

6 To conduct IP-related studies focusing on network architecture, network capabilities, network evolution, service and performance aspects, and access arrangements to achieve interoperability in the multi-vendor and multi-network- operator environments.

7 Particular areas of study key to this evolution are IP-based network architectures, IP-based network performance, IP transfer capabilities, IP-VPN (virtual private network) services, IP-based network resource management and access arrangements.

8 To conduct the remaining studies in the area of B-ISDN resource management, performance and the ATM Layer and its adaptation and interworking. To encourage harmonisation of IP- related and GII studies across the ITU-T study groups through the evolution and further development of the ITU-T IP and GII projects.

9 To collaborate with other standardisation bodies in identifying gaps in the standardisation programmes concerning IP networking and to develop proposals and Recommendations to advance the necessary work.

16 GII Aspects The objectives of the GII Driving forces, trends and directions The role of the ITU The current situation

17 GII Objectives The GII must be designed to : enable information providers and users (e.g. individuals, information users, information providers, and information service providers) to communicate securely with each other any time and anywhere at acceptable cost and with acceptable quality

18 provide a set of communication services support a multitude of open applications embrace all forms of information and information generation (audio, text, data, image, video, etc.) and of its use and transportation operate in a transparent, user-friendly and straightforward way

19 provide seamless, interconnected and interoperable communication networks, information processing equipment, data- bases and terminals (including TV-sets) enable competition between the players in the information and telecommunications (including broadcasting) sectors

20 Driving Forces the convergence of technologies in use within telecommunications, computers, consumer electronics and the move of content provision industries towards digital technology the new business opportunities, created by the unbundling of services made possible or necessary by deregulation, and other commercial and/or open market pressures

21 Teledensity Industrialised countries - 48 (18) Middle income countries - 10 (2.3) Least developed countries - 1.5 (0.01) World average - 11.5 –(PCs per 100 inhabitants)

22 Trends and Directions The GII will not, initially, require or employ new network capabilities, but will define how a multiplicity of existing capabilities will interwork in the context of a "federation of networks". However, standardisation activities related to the GII must permit new network capabilities and technologies to be introduced.

23 Networking Directions

24 The role of the ITU The goal of the ITU is to play a "catalytic role" in facilitating the development of truly global information infrastructures through its work on standardisation, by offering a platform for discussions of a general regulatory framework and as a link between developed and developing countries.

27 Contents - IP Aspects Background ITU actions The ITU-T IP Project Future plans

28 IP Aspects Explosive growth of IP based networks Data traffic growing ten times faster than voice traffic In near future will account for over 80% of all traffic on telecomms networks Business directions are changing

29 Shorter development cycles Shorter life cycles for services and products Standards bodies must be able to respond

30 Interoperability of IP and telecomms networks and of their services is of major concern IP-based services are required with the speed, capacity, ease of use, reliability and integrity that has been associated with the world wide public telephone network

31 ITU-T Actions Study Group 13 appointed as Lead Study Group for IP related aspects Guidelines for collaboration with the ISOC/IETF prepared by TSAG including: –how to interact on work items –representation –document sharing

32 All ITU-T Study Groups actioned to review their Questions to determine how best to address the development of standards for IP-based networks in their specific area of responsibility

33 IP-based networks were recognised as a key strategic area for the ITU by the October 1998 ITU Plenipotentiary Conference Two Resolutions were passed concerning: –involvement in ICANN –strategic review of ITU IP related studies

34 The ITU-T IP Project In its capacity as Lead Study Group for IP related studies Study Group 13 has developed an ITU-T IP Project which: –is separate from, but closely related to GII studies –is intended to encompass all related ITU-T work

35 Scope of the Project

36 Project Areas 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

37 Area 4 - Multimedia applications over IP signals 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 Area 8 - Performance

38 Area 9 - Integrated management of telecom and IP-based networks Area 10 - Security aspects Area 11 - Network capabilities including requirements for resource management Area 12 - Operations and Maintenance (OAM) for IP

39 Future Plans Study Groups will continue to build links with the IETF with the objective to: –avoid duplication of work and divergent standards –collaborate where appropriate Study Group 13 will continue to develop and manage the IP Project with the assistance of the other Study Groups.

40 Workshop on IP-networking and Mediacom-2004 Held on 24 to 26 June 2001 Objectives were to introduce Mediacom-2004 to a wider audience, to further develop this and the ITU-T IP Project, to identify key study areas and identify standards coordination issues for discussion with other standards bodies Presentations and summaries can be found at T/workshops/ipnetwork_mediacom2004/program. html

41 Key issues from the workshop Need for harmonisation of IP QoS classes and for the interworking between existing and new QoS mechanisms. Relationship of QoS to billing and accounting. Importance of management, not only for networks but also for service relations and QoS Importance of private IP VPNs Transition to Next Generation Networks

42 Satellite Intersector Coordination Group (ICG SAT) The Intersector Coordination Group on Satellite Matters was first established at the World Telecommunication Standardisation Conference in 1993 to coordinate the review of Recommendations being developed in ITU-R and ITU-T in order to assure a continuing and full integration of satellite transmission medium in public networks, taking account the application of emerging technologies and services

43 Activities reviewed and updated the workplans of ITU-T and ITU-R Study Groups relevant to satellite matters considered impact on future activities of ICG- SAT of decisions concerning the refinement of the ITU Sectors identified areas in satellite communications that require coordination prepared reports on a number of topics including IP/Satellite related matters, service and network convergence and working methods Next meeting is in Turkey, 26 to 28 June 2001
