  1. Developments of future networks CHAESUB LEE, Chairman of ITU-T SG13

  2. Highlight of Current Activities Study status on future networks in ITU-T SG13 • 6 Approved Recommendations: • Y.3001: Objective and Design Goals • Y.3011: Framework of network virtualization for future networks • Y.3021: Framework of energy saving for future networks • Y.3031: Identification framework in future networks • Y.3041: Smart Ubiquitous Networks (SUN) – Overview of SUN • Y.3042: SUN- Smart Traffic Control and Resource Management Functions • 10 Draft Recommendations (work programme): • Y.amnsa: Requirements and Architectural Framework for Auto Manageable Future Networks and Services • Y.FNsdn: Framework of SDN for carrier networks in Future Networks • Y.FNsdn-fm: Requirements of formal specification & verification methods for SDN • Y.Fnvirtreq: Requirement of network virtualization for Future Networks • Y.FNDAN: Framework of Data Aware Networking for Future Networks • Y.FNID-config: Configurations of node identifiers and their mapping with locators in future networks • Y.energyMRM: Energy measurement of networks • Y.Fnsocioeconomic: Socio-Economic Aware Design of Future Network Technology • Y.SUN-cdf: Functional architecture of content delivery in SUN • Y.SUN-content: Framework of content awareness for Smart Ubiquitous Networks

  3. Hurdles on study of future networks • Clearance of future networks: • Definition: “A network able to provide services, capabilities, and facilities difficult to provide using existing network technologies. A future network is either: 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. • 4 Objectives: Awareness (Service-, Data-, Environmental-, Social and Economic- awareness) • 12 Design goals: service diversity, functional flexibility, virtualization, data access, energy consumption, service universalization, economic incentives, network management, mobility, optimization, identification and reliability & security  Objectives/Targets, scope, directions and technologies: NOT CLEAR • Use of the name (title): • Considerations for identifying the title: • Incorporate: key features/characteristics, key technologies, market trends, business trends and/or user needs as soon as possible • Avoid: terms difficult to define, clarify scopes and boundaries  Future networks: Noun or Pro-noun, aiming for service, networks, technology, business or user needs (?)

  4. Difficulties on study of future networks • So far, difficult to imagine “a network replace existing networks” and also • difficult to find out set of technologies to cover full scope of future network • Less industries having interest to invest for long term projects Technology developments regardless of defined networks Top down or Bottom up Name of Network & Definition Technical Area 1 (e.g. Services & Applications) Requirements & Capabilities Technology Area 2 (e.g., Platform A) Technology Area 2 (e.g., Platform A) SDN Technology Area 3 (e.g., Transport) Functions & Architecture Technology Area 4 (e.g., Transmission) Mechanisms Technology Area 5 (e.g. Medium) Technology Area 5 (e.g. Medium) Protocols timeline

  5. Strategic Direction and Challenges Future Networks (as a vision: Y.3001) • Use Future Network as a flag (vision) • Collect candidate technologies especially collaborating with research communities including academy • Identify milestones with clearer scope and a set of candidate technologies • Identify clear title to represent each milestone (e.g., ABC, DEF, 123, XYZ) Technical Area 1 (e.g. Services & Applications) Technology Area 2 (e.g., Platform A) Technology Area 2 (e.g., Platform A) Technology Area 3 (e.g., Transport) Technology Area 4 (e.g., Transmission) Technology Area 5 (e.g. Medium) Technology Area 5 (e.g. Medium) Timeline 123 ABC DEF XYZ

  6. Next Steps / Actions • Collect vision (targets and scopes) of each SDOs • Collect technologies which consider as candidate for the vision of each SDOs • Identify common milestone(s) with target vision and set of technologies which will be supported by GSC collaboration • Develop “ROADMAP” for future network collaboration of GSC • ITU-T should be taken “A Prime Role”
