I. FG-FN results

Future Network activities in ITU-T 1.2009 ITU-T Study Group (SG) 13 established two groups to study Future Networks Question 21 (Q.21) Standing group Limited to ITU-T members Possible to make ITU-T recommendations Focus Group on Future Networks (FG-FN) Temporary group (~12.2010) Open to everybody Asks its parent SG to make its deliverable ITU-T recommendation Since the establishment of FG-FN, all technical discussions were in FG-FN; Q.21 worked as a caretaker of FG-FN

FG-FN Scope The Focus Group, by collaborating with worldwide future network (FN) communities (e.g., research institutes, forums, academia and etc), aims to collect and identify visions of future networks, based on new technologies, assess the interactions between future networks and new services, familiarize ITU-T and standardization communities with emerging attributes of future networks, and encourage collaboration between ITU-T and FN communities.

To achieve this objective the Focus Group will FG-FN Objective The objective of the Focus Group is to document results that would be helpful for developing Recommendations for future networks. To achieve this objective the Focus Group will gather new ideas relevant to Future Networks and identify potential study areas on Future Networks, describe visions of the Future Networks, identify a timeframe of Future Networks, identify potential impacts on standards development, and suggest future ITU-T study items and related actions.

Milestones 1. 2009; ITU-T SG13; Establishment of FG-FN Question 21 (Q.21) was also established 6.2009; FG-FN #1 @Lulea, Sweden Collocated with FIREweek 11.2009; FG-FN #2 @Salt Lake, US Collocated with GENI Engineering Conference (GEC) 1.2010; FG-FN #3 @Geneva, Switzerland Collocated with NGN-GSI 3.2010; FG-FN #4 @Tokyo, Japan Collocated with Int. Symposium on ICT System Testbed 4.2010; ITU-T SG13; FG-FN lifetime was extended till 12.2010 6.2010; FG-FN #5 @Geneva, Switzerland 9.2010; FG-FN #6 @Geneva, Switzerland 10.2010; FG-FN #7 @Busan, Korea 11.2010; FG-FN #8 @Ljubljana, Slovenia 1.2011; ITU-T SG13; FG results review 1st half: information collection phase; 2nd half: document development phase

Management Chairperson Vice-chairpersons Mr. Takashi Egawa (NEC) Succeeded the position from Mr. Naotaka Morita (NTT) at FG-FN #4 (3.2010) Vice-chairpersons Mr. Hyoung-Jun Kim (ETRI) Prof. Dr. Alex Galis (UCL)

Developed deliverables Developed overall vision document and three supporting specific technology document, plus two others Overall vision document ‘Future Networks: design goals and promising technologies (FNvision)’ Identifies FN’s high-level objectives, design goals and time frames Mature to publish Three supporting specific technology document Framework of Network Virtualization (FNvirt) Overview of Energy Saving of Networks (FNenergy) Identifiers and Identification processes in Future Networks (FNidentification) Two misc documents Terminology Project descriptions; information on research activities going in various places

Appropriate timeframe: 2015-2020 Key findings (1/3) New social requirements (e.g., environment), New application areas (e.g., M2M, cloud, smart grid), new implementation technologies are emerging These may introduce the development of new network architectures; we call this Future Networks Appropriate timeframe: 2015-2020 Possible differentiator of FN from existing network architectures Environment awareness; ‘of networks’ and ‘by networks’ Service awareness; how to manage huge amount of extremely divers services? Data awareness; today’s network is mainly used to access data, but not designed for that Social-economic awareness; architecture must pay attention to the influence of social-economic issues on e.g., evolvability or service universalization As far as FG-FN reviewed, there is no consensus on the architecture or the priority of requirements

Key findings (2/3) Various important technical areas are emerging FG developed three deliverables for each areas (Network virtualization, electric power savings, and identification processes and identifiers) There are other important areas, but documents were not developed because of limited resources Network virtualization Enabler for co-existence of different network architecture in a physical network Important tool for network management to manage diversified requirements of each applications Electric power savings Important to reduce environmental impact as well as avoiding power consumption (and resulting heat, etc.) to become the limitation for network operation Identification processes and identifiers Identifiers themselves are not new; but they are the starting point for everything, in particular for better mobility and for data acces

Key findings (3/3) To design FN, wider collaboration than traditional ICT framework is necessary. Today’s promising areas are all interdisciplinary ones between ICT and other industries Cloud: computer, smart grid: power, IoT: health, vehicle, etc. ICT has become an infrastructure of every industry, so we need to learn their needs to design future networks We can’t design smart grid ready network without understanding power industry’s requirements

II. Future steps

Proposal to SG13 at 1.2011 Documents No new GSIs, no WP or question This will be discussed and decided at the FG-FN#8. Documents FN vision approve it as a recommendation immediately Distribute it to all SG13 questions to consider what to do next Network virtualization (FNvirt), Power savings (FNenergy): continue development at Q.21/13 Identification process (FNidentifier): to stop development; if necessary it can easily re-started in Q.21/13 or some other groups No new GSIs, no WP or question FNs is a very important topic, but it is still in the pre-standardization phase Discussion point: if collaboration with other industries is the key, what is the appropriate way to handle this? There is Q.21, but it’s resources are very limited.
