Contents OutlineContents Outline
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.
We see growing concerns about the following aspects on current network, including IP based networks: • Scalability, ubiquity, security, robustness, mobility,
heterogeneity, Quality of Service (QoS), re-configurability, context-awareness, manageability, data-centric, network virtualization, economics, etc.
These topics will be the requirements for FN, which will meet future services and overcome the deficiencies of the current IP based network.

Motivation (1/3)Motivation (1/3)
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 studied based on clean-slate approach.
4
Motivation (2/3)Motivation (2/3)
Standardization/Research efforts on clean-slate designs for FN• GENI, FIND projects in the US
• FP7, FIRE projects in EU
• ISO/IEC JTC1/SC6 has just started the new work on FN
NGN is successfully settled down in SG13• based on all-IP technologies and incremental designs
Therefore, ITU-T has built a new Question (Q.21) on FN based on clean-slate approach for the new study period (2009-2012) of SG13 and FG-FN as a lead group of future view on telecommunication network and services.
5
Motivation (3/3)Motivation (3/3)
Future Network (FN) : A network which is able to provide revolutionary services, capabilities, and facilities that are hard to provide using existing network technologies.
6
Definition of FNDefinition of FN
The FN is the network of the future which is made on Clean-slate Design.
It should provide futuristic functionalities beyond the limitations of the current network including Internet (IP).
Revolutionary approach should be considered for the FN.
The FN should not dependent on the current technologies and solutions.
FN provides mechanisms that benefit every participant as much as they contribute.
The backward compatibility may or may not be required.

Role and Scope• Produce document(s) on vision and service scenarios of
future networks as well as on problem statements• Produce inputs to new Recommendations on:
• Requirements of the future networks, which provide enhanced features as well as on gap analysis between existing technologies including recent evolving technologies and the requirements of future networks.
• Framework and model of future networks, which may provide a common basis for further development of specific recommendations on functions and facilities.
• Collaborate with other standards bodies

Q.21- Future networksQ.21- Future networks
ISO/IEC JTC1/SC6 wants to collaborate with ITU-T for this topics • ISO/IEC JTC1/SC6 has just started the new work on FN.
• Technical Report on “Future Network : Problem Statement and Requirements”
• Editor : Myung-Ki SHIN (ETRI)
• ISO/IEC JTC1/SC6 efforts could aligned with ITU-T’ activities If the joint-work (e.g., common text) is approved, the
same documents (Subpl. and TR) could be published. We encourage CJK to participate to this work and
solicit further contributions (esp. co-editors in Q.21)

Collaborative Issues with ISOCollaborative Issues with ISO
Chairman • Naotaka Motita (NTT) • Vice-Chairmen can be welcome from research
organizations/projects beyond ITU-T regular participants. Role and 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.

GENI Project Office Announces $12M forCommunity-Based GENI Prototype Development
July 22, 2008
The GENI Project Office, operated by BBN Technologies, an advanced technologies solutions firm, announced today that it has been awarded a three year grant worth approximately $4M a year from the US National Science Foundation to perform GENI design and risk-reduction prototyping.
The funds will be used to contract with 29 university-industrial teams selected through an open, peer-reviewed process. The first year funding will be used to construct GENI Spiral 1, a set of early, functional prototypes of key elements of the GENI system.
18
Provides the very first, national-scale prototype of an interoperable infrastructure suite for Network Science and Engineering experiments
Creates an end-to-end GENI prototype in 6-12 months with broad academic and industrial participation, while encouraging strong competition in the design and implementation of GENI’s control framework and clearinghouse
Includes multiple national backbones and regional optical networks, campuses, compute and storage clusters, metropolitan wireless and sensor networks, instrumentation and measurement, and user opt-in
Because the GENI control framework software presents very high technical and programmatic risk, the GPO has funded multiple, competing teams to integrate and demonstrate competing versions of the control software in Spiral 1
GENI Spiral 1GENI Spiral 1
Nothing like GENI has ever existed; the integrated, end-to-end, virtualized,and sliceable infrastructure suite created in Spiral 1 will be entirely novel.19
