Global Collaboration on Future Network Standardization

1. Global Standards Collaboration (GSC) 14 Global Collaboration on Future Network Standardization Hyoung-Jun KIM, Chair of PG210, TTA

2. Background (1/2) • 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)

3. 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.

4. Current Activities (1/7) • 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 Requirements • Requirements of Network Virtualization

5. Current Activities (2/7) • Study items (or deliverables) of Q.21/13 to be considered include, but are not limited to: • Problem statement on current IP-based network architecture • Design goals and general requirements for the FN   • Gap analysis between existing standards and FN • Meta 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

6. Current Activities (3/7) • 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.

7. Current Activities (4/7) • 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.

8. Current Activities (5/7) • 1st Meeting of FG-FN • Luleå, 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 meeting • More than 20 contributions • FP7/FIRE projects in Europe are introduced. • China, Korea, and Japan project are also discussed. • FIRE and ITU-T Joint Meeting • Target time frame of FN (2015-2020) was clarified. • The two draft deliverables are agreed to develop.

9. Current Activities (6/7) • ISO/IEC JTC1 • SC6/WG7 has launched similar standardization activities on Future Network. • Future Network : Problem Statement and Requirements

10. Current Activities (7/7) • Korean Activities on FN Issues • Actively 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.

11. Challenges • 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.

12. 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.

13. Future Networks : Clean-slate design • Two Design Choices • Incremental Design : A system is moved from one state to another with incremental patches • Clean-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.

14. New Design Goals for FN • Scalability • Security • Mobility • Quality of Service • Heterogeneity • Robustness • Customizability • Economic Incentives Scalability Security Economics Mobility FN : Design Goals Customizability Quality of Service Robustness Heterogeneity

15. Next Steps/Actions • Global collaboration on Future Network required • To make good collaboration with relevant organizations/projects • To collect and identify visions of future networks with relevant organizations/projects • To 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.
