Standardization of Future Networks -- networks of 2015-20 and beyond --

1. ITU Workshop on “Bridging the Standardization Gap”(Vientiane, Lao People’s Democratic Republic, 30-31 July 2012) Standardization of Future Networks-- networks of 2015-20 and beyond -- Takashi Egawa, Rapporteur of Q.21, SG13 NEC Corporation t-egawa@ct.jp.nec.com

2. Again new network architecture? Really? What’ this new buzzword? Is there something new? What’s the benefit for us? Is it true or hype? ISDN was said to change the world… B-ISDN and ATM was investigated… I’m an old guy, I still remember IN… Then came the Internet from outside… Recently ITU promoted NGN… Now they sell us Future Networks…

3. New architecture != new services Water industry’s product is always the same • New architecture becomes necessarywhen balance among important issue varies • Line cost versus Node cost: Optical fiber reduced line cost: we can simplify node by sending more complicated (text-based) control messages • Hard-disk cost is still decreasing • New service emergeswhen new end-user device emerges • Personal Computer  internet • Mobile phone  made everything personal • Bigger computer (Data center)  cloud • Cheap sensors  M2M

4. Environment of 2015-20 (1) • New end-devices/services • Bigger computer behind the network (cloud): The long-time dream of computer science. No alternative in the near future. Cloud provider will become influential on networks. • Sensors (M2M): maybe if good business model emerges. # of terminals explodes • Devices • Improvement speed of various devices (optical transmission, processors, memories, etc.) may decrease. Traffic explosion (data, bandwidth, # of terminals, etc.) cannot be handled solely with device improvement.  network will be more complicated

5. Environment of 2015-20 (2) • Speed of improvement • May not be so drastic as these 20 years •  Social requirements will become influential again •  traditional requirements such as reliability will become influential again • Environmental issue • Peak oil, Climate Change, … some of them may become life and death problem in 20 years

6. Definition of FN: A network able to provide services, capabilities, and facilities difficult to provide using existing network technologies. A Future Network is either: Target Date: roughly2015-2020 Vision of Future Networks (Y.3001) Service awareness Data awareness 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. 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 4 objectives and12 design goals

7. Aims of standardization Prune options (future possibilities)Restrict the freedom of innovation Non-IP packet format is almost extinct Optimal for particular purpose, but non-standardized (ie, customized) product cannot become majority if standardization works well Define the area of competition, making it severer (=benefit for consumers) Simplify our life Makes some part of our life ‘decided’ We concentrate on remaining part Expand the market By making average users easier to understand/use

8. Questions for FN standardization Do we have enough options? Are they mature enough to prune, or to freeze innovation?Which part is mature, which is not? Is the emerging market clear enough? Can we expect enough participation from industries?ITU-T is contribution driven (no progress without contribution). Do industries ready to compromise to expand the market?If we specify standards, do market respect our specifications? FNs was in their early stage, so it was not appropriate to define overall architecture It is now changing.

10. Future Networks in ITU-T SG13 (Future Networks including NGN and mobile) leads this activity Approved/agreed on three specifications Future Networks (FNs) study is now expanding in SG13 Started in Focus Group on Future Networks (FG-FN) and Q.21/13 FG-FN: temporary, Q.21: standing Smart Ubiquitous Network (SUN), a short-term solution is currently studied in several Qs in SG13

11. ITU-T FN activity timeline 2009 2010 2011 2012 FG-FN Future Networks (long-term future) Q.21 start 5.2011 Vision (Y.3001) 10.2011 Net. virtualization (Y.3011) energy saving (Y.3021) identifier (Y.3031) socio-economic autonomic-mngt SDN Data-aware net Concept Proposal SUN (short-term) SUN overview Concept discussion Other SUN docs

12. Network Virtualization for FNs (Y.3011) • Definition of “network virtualization": • A technology that enables the creation of logically isolated network partitions over shared physical networks so that heterogeneous collection of multiple virtual networks can simultaneously coexist over the shared networks. This includes the aggregation of multiple resources in a provider and appearing as a single resource. • Motivation • Key technology for Service Awareness of FNs • Diverse services • Heterogeneous network architectures • Problem spaces & design goals • Coexistence of multiple networks • Simplified access to resources • Flexibility in provisioning • Evolvability • Design goals • Isolation, network abstraction, topology awareness and quick reconfigurability, performance, programmability, management, mobility, wireless

13. Energy saving for FNs (Y.3021) • Definition of "Energy saving of networks": • Network capabilities and their operations where the total energy for network equipment is systematically used in an efficient manner Energy Management Function • Approaches • Reduction of required network capacity • Improvement of efficiency • Possible functions • Energy Control & Measurement Function • Three levels of technologies • Energy Management Function • Function to calculate the optimum case of operation • Status Information Base • Database of energy-related information DataCollecting Sub-function Operating Sub-function Optimisation Sub-function Operation Access Data Energy Control & Measurement Function Status Information Base [e.g., power consumption, traffic] Network level [e.g., routing path] Data Equipment level [e.g., node sleep] Device level [e.g., device clock]

14. Identification Framework for FNs (Y.3031) • Motivation • Essential to recognize potential identifiers pertinent to networks envisioned in ITU-T Recommendation Y.3001 • So, specify an identification framework that includes node IDs, data IDs, user IDs, service IDs and location IDs in its scope • Identification Framework • Logically connects communication objects to physical networks • Includes four components: • ID Discovery Service • ID Spaces • ID Mapping Registries and • ID Mapping Service • Detail specifications of these components would be provided by future Recommendations.

15. Y.FNsocioeconomic Is this technology good for society? Economically reasonable? Some interfaces/mechanisms are too integrated, and difficult to improve because too many parties are involved When a technology is given, Y.FNsocioeconomic Lists and describes methods to assess socio-economic effect of the technology Analyze potential tussles among parties Helps design/select appropriate technology for Future Networks
