Q12 Evolution towards integrated multi-service networks and interworking

Role of Q.12/13 Motivation The rapid growth and the embedded base of legacy telecommunications networks have necessitated a strategy of evolution towards integrated multi- service networks which connect to enterprise and home networks. Due to popularity of the IPTV and transformation of networks to NGN it has become necessary to include study of home networks. Thus the focus of this Question will include activities related to IP television (IPTV) and home networks. This Question will address items such as: determination of how best to carry narrow-band and broadband services of a fully integrated IP-based network across non-IP based networks (e.g. FR and ATM); description of interworking of services, including definition of protocol requirements; interworking of services between home network operator administered networks.

Role of Q.12/13 Tasks Creation of, maintenance and enhancement to the Recommendations in Y.1400 series Maintenance of Recommendations Y.2261, Y.2262 and Y.2271 Maintenance and enhancement to the Recommendations in I.500 series Maintenance and enhancement to Recommendations Q.933, Q.933bis, X.36, X.76, X.84, X.142, X.144, X.145, X.146, X.147, X.148, X.149, X and X.272 and the development of new Recommendations as deemed necessary Completion of draft Recommendations already under discussion in Questions 12/13 Development of new Recommendations related to home network and their interworking aspects with the operator administered networks Development of new Recommendations related to interworking to support IPTV services 35

Q24 Service scenarios, deployment models and migration issues

Role of Q.24/13 Motivation As NGN and Future Networks scope covers wide areas of network, a set of promising service scenarios and deployment models of NGN and Future Networks are very useful to accelerate the NGN and Future Networks deployment. All the scenarios should be initiated from the user point of views, which would be described as use cases. At the same time, operators of existing telecommunication networks have expressed concerns connected with the necessity of full replacement of their network equipment when migrating from traditional telecommunication networks to NGN and Future Networks. For Future Networks, more and more new technologies will be introduced, e.g. Cloud Computing, IoT, etc. The architecture and deployment of Future Networks will be probably largely different from the existing telecommunication networks. Foregoing requirements will be still available when existing telecommunication networks or NGN migrate to Future Networks.

Role of Q.24/13 Tasks Develop documents on NGN and Future Networks service scenarios including emerging services and converged services. Develop documents on NGN and Future Networks based IPTV service scenarios that converge traditional broadcasting services and telecommunication services over the NGN and Future Networks environment. Develop documents on service scenarios of use cases and 3rd party services for ubiquitous environments. Develop documents on migration scenarios to NGN and Future Networks. Develop documents on decision factors for selecting migration scenarios and migration criteria through analysis of the scenarios. Continue documents currently under way. Documents produced under this Question will normally be published as Supplements or will progress through, or in coordination with, other related Questions. 39

Y.2055 (Y.ipv6-object) Framework of Object Mapping using IPv6 in NGN
This Recommendation describes requirements and mechanisms for object mapping using IPv6 in NGN. Basic concept and requirements of object mapping using IPv6 Mapping architecture and relationships between identifiers Mechanisms for object mapping using IPv6 Direct mapping vs. Indirect mapping Direct mapping: An object at application layer is directly reachable to host entity at Point of Attachment (PoA) which IP is terminated. Indirect mapping: An object at application layer is remotely reachable through non-IP interface to host entity at PoA which IP is terminated. An object is located outside of physical network attachment which IP is terminated.

Q.21 - Future Networks

Role of Q.21/13 Question 21/13 – Future networks
Future network - A network able to provide revolutionary services, capabilities, and facilities that are hard to provide using existing network technologies (ITU-T Q.21/13 Jan meeting report ). FN is the network of the future: made using Clean-slate Design. It should provide futuristic functionalities beyond the limitations of the current network including Internet (IP). FN provides mechanisms that benefit every participant as much as they contribute. Backward compatibility may or may not be required. [Note] : Clean-slate approach is understood as a design principle, not deployment aspect.

Focus group on Future Networks
The group was established in The objectives were to gather new ideas, identify potential study areas, describe vision with a targeted timeframe, and suggest future actions. In 2009 and 2010, FG held eight meetings led by Mr. Takashi Egawa, NEC, Japan, and collocated with FN-related academic events. Project descriptions in 135 pages summarizes the research activities. As a Future Networks vision, FG has found new requirements for networks, and identified four objectives (service-, data-, environment-, and social and economic awareness), and twelve design goals. It is assumed that the target date for trial services and phased deployment of FNs falls roughly between 2015 and The document becomes a good candidate for the first Recommendation (Y.3001) on Future Networks. FG identified three technology areas likely to be used: Network virtualization, Energy-savings of networks, and Identifiers and Identification processes.

Vision of Future Networks (Y.3001)
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: roughly Service awareness Data awareness 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. Service Diversity Functional Flexibility Data Access Virtualization of Resources Network Management Identification Mobility Reliability and Security Environmental awareness Social and economic awareness Energy Consumption Service Universalization Optimization Economic Incentives 4 objectives and 12 design goals

Major results of Q.21/13 in 1/2011 Future Networks
Successfully received FG-FN outputs Determined draft Y.FNvison (Y.3001) under TAP process Initiated three drafts on network virtualization, energy saving, and IDs. Initiated seeking collaboration with JTC1/SC6 via common mailing list
