Vientiane, Lao Peoples 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 firstname.lastname@example.org ITU Workshop on Bridging the Standardization Gap (Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012)
Again new network architecture? Really? ISDN was said to change the world… B-ISDN and ATM was investigated… Im an old guy, I still remember IN… Then came the Internet from outside… Recently ITU promoted NGN… Now they sell us Future Networks… Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012 2 What this new buzzword? Is there something new? Whats the benefit for us? Is it true or hype?
New architecture != new services New architecture becomes necessary when 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 emerges when new end-user device emerges Personal Computer internet Mobile phone made everything personal Bigger computer (Data center) cloud Cheap sensors M2M Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012 3 Water industrys product is always the same
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 Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012 4
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 Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012 5
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: roughly 2015-2020 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. Vision of Future Networks (Y.3001) 4 objectives and 12 design goals Service awareness Data awareness Social and economic awareness Environmental awareness Energy Consumption Optimization Service Universalization Economic Incentives Service Diversity Functional Flexibility Virtualization of Resources Network Management Mobility Reliability and Security Data Access Identification Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012
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 Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012
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 Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012

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 Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012
13 Energy saving for FNs (Y.3021) Energy Control & Measurement Function Status Information Base [e.g., power consumption, traffic] Equipment level [e.g., node sleep] Network level [e.g., routing path] Device level [e.g., device clock] Operation Data Energy Management Function Operating Sub-function Optimisation Sub-function DataCollecting Sub-function Access 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 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 Data Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012
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.

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 15 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 Vientiane, Lao Peoples Democratic Republic, 30-31 July 2012
