Again new network architecture? Really?

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…

What’ this new buzzword?Is there something new?

What’s the benefit for us? Is it true or hype?

New architecture != new services

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 internetMobile phone made everything personalBigger computer (Data center) cloudCheap sensors M2M

Water industry’s 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

DevicesImprovement 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

Environment of 2015-20 (2)

Speed of improvementMay not be so drastic as these 20 years Social requirements will become influential again traditional requirements such as reliability will become influential again

Environmental issuePeak oil, Climate Change, … some of them may become life and death problem in 20 years

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

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 and12 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

Aims of standardization

Prune options (future possibilities)Restrict the freedom of innovation

Non-IP packet format is almost extinctOptimal 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 marketBy 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.Vientiane, Lao People’s Democratic Republic, 30-31 July 2012

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

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

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

MotivationEssential 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 FrameworkLogically connects communication objects to physical networks Includes four components:

ID Discovery ServiceID SpacesID Mapping Registries andID Mapping Service

Detail specifications of these components would be provided by future Recommendations.

Is this technology good for society?Economically reasonable?

Some interfaces/mechanisms are too integrated,and difficult to improve because too many parties are involved
