Fostering worldwide interoperability 2Geneva, 13-16 July 2009

The Future Network (FN), which is anticipated to provide futuristic functionalities beyond the limitation of the current network including Internet, is getting a global attention in the field of communication network and services.

To support the requirements of future emerging applications and users, telecommunications technologies beyond current IP oriented technologies will need to be developed.

To support the development of global and harmonized frameworks (e.g. requirements, functional architectures and protocols)

Background (1/2)

Fostering worldwide interoperability

Background (2/2)

Future Networks have become a part of global agenda.

ITU-T (Q21/SG13 and FG-FN), ISO/IEC JTC1/SC6 IRTF (International), GENI/FIND (US), FP7/FIRE (EU), FIF(Korea), AKARI/NwGN (Japan), etc.

However, all these activities seems to be in their early stage of investigation.

Global harmonization between these different activities are extremely important and necessary to build up globally interoperable future ICT infrastructures.

ITU-T Q.21/SG13

The title of SG13 in the new study period (2009-2012) is “Future Networks including Mobile and NGN” reflecting the importance of “Future Networks”.

A new Question on Future Networks has been approved as Q21/13 and has started the works.

Future Network : Vision, Concepts, and RequirementsRequirements of Network Virtualization

Current Activities (1/7)


Study items (or deliverables) of Q.21/13 to be considered include, but are not limited to:

Problem statement on current IP-based network architectureDesign goals and general requirements for the FN Gap analysis between existing standards and FNMeta architecture (network virtualization, cross-layer communications) and architectural framework for the FN Incorporating new communication and service technologies into FN Identifying functions and capabilities to support new services for the FN



ITU-T FG-FN SG13 has established “Focus Group on Future Networks (FG-FN)” to share the discussion on Future Networks and ensure global common understanding about Future Networks with collaboration and harmonization with relevant entities and activities.

Supported by the Focus Group, SG13 can establish the clear roadmap of studies for Future Networks and good collaboration with relevant organizations/projects which are imperative to standardization activities for the Future Networks.



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 technologiesassess 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.



1st Meeting of FG-FNLuleå, Sweden, June 29-July 3 (co-located with FP7/FIREweek event)

Chairman : Naotaka Morita (NTT, Japan)Vice-chairman : Hyoung Jun Kim (ETRI, Korea)

Outcome at the first meetingMore than 20 contributionsFP7/FIRE projects in Europe are introduced.China, Korea, and Japan project are also discussed.FIRE and ITU-T Joint MeetingTarget time frame of FN (2015-2020) was clarified.The two draft deliverables are agreed to develop.



ISO/IEC JTC1SC6/WG7 has launched similar standardization activities on Future Network.

Future Network : Problem Statement and Requirements



Korean Activities on FN IssuesActively involved in standardization activities

ITU-T Q.21/13, FG-FN, ISO/IEC JTC1/SC6 Management Team

Domestic Future Internet Forum (FIF) was launched in 2006.

A lot of members from universities, institutes, and industries

ETRI has started the work on development of virtualized programmable platform for Future Network research and experimentation.PG 220(Future Internet) of TTA has recently launched with its ToR.



Taking into consideration the importance of global connectivity and interoperability between devices, networks, services and applications, global harmonization on Future Network between these different activities are extremely important and necessary to build up globally interoperable future ICT infrastructures.

Challenges


Future Networks : Initial thinking

For the sake of better understanding of Future Networks, an initial definition of ‘Future Networks’ was proposed in Q.21/13 meeting

Future Network (FN) is a network which is able to provide revolutionary services, capabilities, and facilities that are hard to provide using existing network technologies.FN provides mechanisms that benefit every participant as much as they contribute. It will be studied based on clean-slate approaches.Clean-slate approach was understood as a design principle, not deployment.



Future Networks : Clean-slate design

Two Design ChoicesIncremental Design : A system is moved from one state to another with incremental patchesClean-Slate Design: The system is re-designed from scratch

It is assumed that the current IP’s shortcomings will not be resolved by conventional incremental and “backward-compatible” style designs. So, the FN designs must be made based on clean-slate approach.

Global collaboration on Future Network requiredTo make good collaboration with relevant organizations/projectsTo collect and identify visions of future networks with relevant organizations/projectsTo establish the roadmap of studies for Future Networks

So, if we agree with the collaboration on FN inside of the GSC, TTA would like to propose this topic to be added in HIS at the next GSC.
