Future Networks: A Vision for Tomorrow's Connectivity

1. Future Networks by ITU-T SG 13 Tatiana Kurakova Counsellor, ITU-T SG 13 WTSA-12 Regional Preparatory Meeting Tashkent, Uzbekistan, 3 April 2012

2. Mission and Mandate of SG 13 Leading Study Group roles of ITU-T SG13 SG13 was NGN group WTSA 2004 • Lead study group for NGN and Satellite SG13 covers ‘Future networks including mobile and NGN’ WTSA 2008 • Lead study group for Future Networks and NGN • Lead study group on Mobility Management and Fixed-Mobile Convergence • Lead study group to coordinate activities related to cloud computing with other relevant study groups

3. Study requirements, architecture, evolution and convergence of future networks Studies focused on network aspects of mobile telecommunication networks, including International Mobile Telecommunications (IMT), wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia network functions, internetworking, interoperability Enhancements to existing ITU‑T Recommendations on IMT. Mission and Mandate of SG13

4. New network appears when important features change Implementation technology, application, … It’s possible to use old one, but optimized one is often more convenient and cheap We can access the internet with telephone & modems ??? Is it time to find a new network ??? Why new network? NGN • NGN features: packet-based, managed QoS, improved security, separation of service/transport stratum, etc. • These are good, may apply in the future, but the focus may shift …?

5. Definition of FN: A network able to provide services, capabilities, and facilities difficult to provide using existing network technologies. A Future Network is either: Vision of Future Networks (Y.3001 – Future Networks: Objectives and Design Goals) a) A new component network or an enhanced version of an existing one, or b) A heterogeneous collection of new component networks or of new and existing component networks that is operated as a single network.

6. Vision of Future Networks (Y.3001) 4 objectives and12 design goals Service awareness Data awareness Service Diversity Functional Flexibility Data Access Virtualization of Resources Identification Network Management Mobility Reliability and Security Environmental awareness Social and economic awareness Service Universalization Energy Consumption Economic Incentives Optimization

7. Four Objectives Environment awareness Service awareness DATA awareness Social-economic awareness FUTURE NETORKS • Environment awareness • FNs should be environmental friendly. • Service awareness • FNs should provide services that are customized with the appropriate functions to meet the needs of applications and users. • Data awareness • FNs should have architecture that is optimized to handling enormous amount of data in a distributed environment. • Social-economic awareness • FNs should have social-economic incentives to reduce barriers to entry for the various participants of telecommunication sector.

8. Design Goals, selection • FNs should have device, system, and network level technologies to improve power efficiency and to satisfy customer’s requests with minimum traffic (Power Consumption) • FNs should have mechanisms for retrieving data in a timely manner regardless of its location (Data Access) • FNs should be designed to provide sustainable competition environment to various participants in ecosystem of telecommunication by providing proper economic incentives (Economic Incentives) • FNs should accommodate a wide variety of traffic and support diversified services (Service Diversity) • FNs should facilitate and accelerate provision of convergent facilities in differing areas such as towns or the countryside, developed or developing countries (Service Universalization)

9. Promising Technologies Network Virtualization In-system Network Management Power Saving of Networks Mobility-enhanced Distributed Networking Network Optimization Data-oriented Networking Network supporting Economic Incentives

10. Supporting specific technology documents Y.3011 (01/12) - Framework of network virtualization for future networks Y.3021 (01/12) - Framework of energy saving for future networks Y.3031 - Identification framework in future networks​ (in AAP LC till 28.03.12.)  Generic Handbook "Future Networks“ (02/12) Deliverables approved and under approval process

11. Future Steps Further Study issues on Future Networks • Functional requirements and Architectures • Required capabilities and enablers • Reference models and Reference Points • Relevant functions to support features which identified in requirements • Identifications for Future Networks • Operations and Managements requirements and functions • Collaborate to develop relevant protocols and necessary mechanisms • Service and application models and capabilities • Migration models • Started investigation on FN’s role for future disasters like 2011 Japan quake

12. Joint ITU-T SG13 and ISO/JTC1/SC 6 workshop on future networks standardization Geneva, Switzerland, 11 June 2012 To identify commonalities and differences in the work progressed by each group, and to assess if those differences can be solved To investigate which standards would be developed as common texts according to Recommendation ITU-T A.23, Annex A | ISO/IEC JTC 1 Standing Document 3 Workshop will be supported by remote participation tools Workshop

13. Thank you for your attention and welcome to ITU-T Future Networks group!

17. Network Virtualization • Network virtualization is the technology that enables the creation of logically isolated network partitions over shared physical network infrastructures so that multiple heterogeneous virtual networks can simultaneously coexist over the shared infrastructures. • Also, network virtualization allows the aggregation of multiple resources and makes the aggregated resources appear as a single resource. • The detailed definition and framework of network virtualization are described in (ITU-T Y.3011 (01/12) “Framework of network virtualization for future networks”).
