It shall not be made available to, and used by, any other persons or entities without the prior written consent of ITU-T.
    • -2- TD 569 PART 1 Study Group 13 objectives for the 2009 – 2012 study period The 2005–2008 study period has been an important and successful period for the development of NGN global standards in ITU-T. Based on the global development of NGN by ITU-T, telecommunication providers and industries in the world are (re)stimulating their businesses based on NGN and are gaining access to enhanced end user services and networks are evolving to NGN. As a result, NGN standards are positioning the core of today’s telecommunications to support evolving business needs. To continue this trend, Study Group 13 has considered the following three dimensions during the development of its objectives. • Scope: Extend NGN requirements, functions and capabilities covering future ubiquitous networking environments (e.g. Ad-hoc networks including RFIDs and Sensors), use of IPv6, home network and service technology, new and converged transport technology, etc.; • Depth: Develop detailed technology to implement networks and services such as detailed functional requirements to support: control protocols (both service and transport control), service and application support platforms to enable convergence with relevant protocols aspects, OAM&P mechanisms, media processing including codec(s), etc.; • Packaging: Make various packages available to show and guide utilization of NGN to support various services and application into actual businesses such as migration to and interworking of NGN, service scenarios (e.g. Voice/MM/Video/IPTV over NGN), Web based services using NGN, 3rd party applications, U-health, e-learning, etc. Key scopes of Study Group 13 work for the next study period In order to maximize the synergy for the experts and minimize the alignment effort among various study groups, the work for Study Group 13 is proposed to be grouped along the following key areas of competence: • Communication networks aspects: study for requirements, functional architectures and their capabilities according to a layered approach such as transport (access and core), transport control, service control and service/application support functions. This study should be based on NGN principles incorporating legacy network aspects. Note: The work of Study Group 13 is not just limited to NGNs, but rather is directed to networks in general. Study Group 13 has developed Recommendations relating to telecommunication networks such as ISDN, FR, ATM based, IP based, MPLS, GII and NGN and continues to retain the responsibility for these network Recommendations. • Content distribution networks aspects: study for the requirements, functions and mechanisms to support distribution of contents which are requested by end users. This will include capabilities to support content finding/metadata, content distribution, rights management and media coding. This study will incorporate broadcasting and other standards integration within the context of evolving NGNs. • Ad hoc networks aspects: study of requirements, functions and mechanisms needed to support configuration of ad-hoc networks used for identifying service discovery and activation, and context description/distribution including peer-to-peer networking. This study should be based on preliminary work in Study Group 13 performed in this study period.
    • -3- TD 569 • Common function aspects: study of functions and relevant capabilities to support identifier management (such as numbering, naming, addressing), identity management (e.g. security frameworks and protection of user data), charging and billing, and management of device(s). This study also will cover regulatory implications including disaster relief and emergency. Classification of Questions for the next study period Fig.1 shows a proposed high level classification of questions aligned with above study objectives and scopes of Study Group13 for the next study period.

    • -6- TD 569 Text of the Questions Question A/13 - Coordination and planning (Continuation of Q.1/13) 1. Motivation A major goal associated with the evolution of implemented networks is to facilitate the convergence of networks and services. This is a complex process and as a result there is a continued need to coordinate ITU-T activities related to the evolution of existing networks, in particular the development of implementation guidelines and standards to facilitate the evolution of current networks. In the 2005-2008 study period, an NGN coordination and release planning function was established and a number of Recommendations supporting this process were developed with many more under way, including development of basic communication capability sets, called Capability Set 1 of NGN Release 1, based on the concept of release planning. Requests to work on new areas such as IPTV, and future networks, other than NGNs, have emerged, and additional such requests may be anticipated even if their particular content is currently unknown. While it has become clear that it is too complex to continue the concept of release planning in an environment where networks are evolving to NGNs, ubiquitous networks, etc. it is recognized that there is an even greater need for a coordination and planning function to support the ongoing evolution of networks. This Question is intended to address the needs associated with the ongoing support of this coordination and planning function. The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: - Supplement 1 to Y.2000 Series: NGN Release 1 Scope - Supplement 2 to Y.2000 Series: NGN Release 2 Scope - Y.2041: Description of Capability Set 1 of NGN Release 1 2. Question Study items to be considered include, but are not limited to: • Ensuring that all elements required for interoperability and network capabilities to support applications globally across the networks are addressed by ITU-T standardization activities • Coordination of the future development of the networks in cooperation with the ITU-T Study Groups and with other Standards Development Organizations (SDOs) e.g. the IETF • Coordination required for interoperability of satellite with NGN and/or future networks and to enable a continuing and full integration of the satellite transmission medium in public networks, taking account of emerging technologies and services
    • -7- TD 569 • Collaboration as appropriate with other SDOs to avoid duplication of standardization work and identification of additional work necessary. • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings? 3.

    • -8- TD 569 Question B/13 - Requirements and implementation scenarios for emerging services and capabilities in an evolving NGN (Continuation of Question 2/13) 1. Motivation With the rapid growth of IP services, including IP Multimedia Telephony and IPTV, demand has been continuously increasing to enhance the network capabilities of multi-service networks. These emerging services and evolution of existing ones, and their variety of deployment scenarios, are placing more and more requirements on networks and are resulting in the need to provide new service and network capabilities. Response to this demand is calling for the creation of an open environment whereby also third parties can develop services and capabilities. In particular, there is now significant support for the NGN to evolve consistently with the concepts of the Service Oriented Architecture (SOA) framework, thereby allowing the composition of interoperable and independent building blocks from both Information Technology and Telecom domains and enabling the integration of rich content, data applications and business processes of the IT domain with intelligent, real-time network capabilities of the Telecom domain. Such an approach will allow for flexible and agile service creation, operation and management, will drive development of capabilities which are portable and reusable across networks, and will allow applications (developed by Service and Network Providers as well as Third Parties) to operate via standardized interfaces (such as Web Services oriented APIs). In the context of a SOA enabled next generation multi-service network environment, study is required, on the basis of business cases and service requirements, to develop implementation scenarios for emerging services as well as to specify the related service and network architectures, including service middleware aspects. These studies, in the context of an open service environment, will allow the specification of the requirements and capabilities imposed on networks (including user networks) by these services, with the goal of maximizing usage of common service and network capabilities and functional building blocks. Key requirements to be considered are ubiquitous support of: seamless end-to-end service operations, service access by mobile and wireline users, wireless/wireline technology independent service access, real time multimedia content delivery, unicast and multicast delivery technologies, SLAs and differentiated levels of Quality of Service, enhanced security, service mobility, service interworking, policy based capabilities, context based capabilities, user identification, authentication and authorization, service discovery, service routing, service brokering, service composition, and both IPv4 and IPv6 protocol technologies. Emerging services include IP Multimedia Telephony applications, IPTV applications, Content Delivery services, Business/Enterprise Communications, Ubiquitous Sensor Network based applications, Identification based services, Context aware services, Third Party services such as Managed Delivery Services and others, applications of User Networks (Home Networks), applications of Grids and related enablers, VPNs and other network virtualization applications, managed peer to peer services, advanced data communication services, as well as other future applications and services based on composition of open service environment capabilities. The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: Y.1261, Y.1281, Y.1310, Y.1311, Y.1311.1, Y.1312, Y.1313, Y.1314, Y.1315, Y.2201, Y.2211, Y.2233.

    • - 11 - TD 569 Question C/13 - Principles and functional architecture for NGNs (including ubiquitous networking) (Continuation of Question 3/13) 1. Motivation The architectural integration of the formerly discrete packet-switched and circuit-switched networks into the NGN supporting various multimedia services requires extension of the architectural principles of both vertical and horizontal perspectives. In vertical aspect, more studies are required in service control and operation support areas to support various multimedia services over various environments. In horizontal aspects, the development of user friendly (or user-oriented) telecommunication capabilities are strongly required to take account of complex situations involving user environments (including home networks) and various access technologies which support convergence. These capabilities are necessary to support the future Ubiquitous Networking vision of NGN. Personal and business services are giving rise to the notion of role-based services within an integrated package of services. NGN will require support for such advanced capabilities which can provide business and personal services to a given user. Features for the control and operation of these services by the user and the network will be required. In addition, end user devices and end user networks like home networks are continuously improving to use services and network capabilities which become important factors for facilitating multimedia services. To establish a set of common principles and architectures for the convergence among services and networks substantial studies and frameworks are required to: a) ensure interoperability of networks and applications; b) facilitate innovation in the use and application of industry capabilities; c) facilitate best utilization of the existing telecommunications infrastructure; d) facilitate mobility of users and devices.

This includes the need for functional reference models, taking into consideration key themes to support ubiquitous environments, and the addition of new functions and/or modification of existing functions. This analysis should include consider the impact on existing Recommendations and interworking cases. A set of preliminary considerations to be taken into account for this study is contained in the Appendix to this question. • Reference Model and functions for Customer Manageable and Home Networks Develop models and functions to allow customers to create, configure, customize, and otherwise customize the network services/resources allocated to them by the network provider, and to allow involvement of third parties in the development of network- supported applications.

    • - 15 - TD 569 Question D/13 – Requirements and frameworks for QoS enablement in the NGN (Continuation of Question 4/13) 1. Motivation A key characteristic of Next Generation Networks (NGN) is the use of a common packet transport for supporting all applications and services. Different types of applications/services (e.g. Web services, IP telephony and IPTV), however, have varied QoS requirements, all of which must be supported by this common packet transport. Hence appropriate mechanisms are needed to achieve the required levels of QoS, especially for applications that are delay- and loss-sensitive. Such applications may also require a large amount of bandwidth, which makes the support for high QoS challenging. To support QoS in a consistent, efficient, dynamic and secure fashion, considerations need to be given to the following aspects: • Application QoS requirements • Involvement of varied types of transport technology (e.g. Ethernet, IP and MPLS in the core network; DSL, UMTS, WiFi, and WiMAX in the access network) and endpoints (e.g. phone, laptop, and set-top box), and multiple administrative domains (e.g. home network and provider network) in an end-to-end path • Availability and accuracy of network topology and load information • Use of multicast • Granularity of QoS control • User nomadicity and mobility • Service level agreement between providers or between provider and user • Provider policy • Use of overlay technology (peer-to-peer or otherwise) for routing around network congestion, reliable multicast support, etc. The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: • Y.1291, “An architectural Framework for Support of Quality of Service in Packet Networks” • Y.2111, “Resource and Admission Control Functions in Next Generation Networks” • Y.2112, “A QoS Control Architecture for Ethernet-Based IP Access Networks”Y.2121, “Requirements for the Support of Flow-State-Aware Transport Technology in an NGN” • Y.2171, “Admission Control Priority Levels in Next Generation Networks” • Y.2172, “Service Restoration Priority Levels in Next Generation Networks”

Question Study items to be considered include, but are not limited to: • What new Recommendations or enhancements to existing Recommendations are needed to enable QoS support in the NGN, especially for performance-sensitive and bandwidth- demanding applications/services (e.g. IPTV)? • What new Recommendations or enhancements to existing Recommendations are needed to leverage NGN QoS mechanisms in overlay networks, such as those for content delivery and reliable multicast? • What new Recommendations or enhancements to existing Recommendations are needed to provide safeguards to QoS mechanisms (e.g. mitigation of denial-of-service and theft-of- service attacks)? • What new Recommendations are needed to provide the resource control and management for achieving end-to-end QoS in a heterogeneous environment involving different QoS mechanisms and multiple provider domains? Note: All new study items will examine existing standards from other SDO’s (e.g. IETF and 3GPP) in the development of new Recommendations or enhancements to existing Recommendations. • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries?

    • - 24 - TD 569 Question H/13 – Impact of IPv6 to an NGN (Continuation of Q.9/13) 1. Motivation The IPv6 is one of the useful delivery protocols for the future fixed and wireless/mobile network environments. From service and application aspects, the necessity of IPv6 will be increasing for the future networking including the ubiquitous network. During the 2004 – 2008 study period of ITU-T, Q.9/13 has defined IPv6-based NGN which supports addressing, routing, protocols and services associated with IPv6 and been developing the related draft recommendations with alignment of the reference model and functional architecture of NGN for analyzing impact of IPv6 to an NGN. To cope with increasing end users/devices, we have to concentrate on more practical solutions to realize IPv6-based NGN according to requirements and functional capabilities developed by Q.9/13. The extension of IPv6 issues could be necessary for supporting the future network environments. 2. Question Study items to be considered include, but are not limited to: • What new Recommendations or enhancements to existing Recommendations are needed to provide general overview of IPv6 based NGN, framework to support signalling for IPv6 based NGN, framework of multi-homing in IPv6-based NGN, and functional requirements for IPv4/IPv6 migration in NGN? • What new Recommendations are needed to provide IP based ID/Locator separation in NGN? • What new Recommendations are needed to provide Protocol procedure and mechanisms for Identification/Naming/DNS extension using IPv6? • What new Recommendations are needed to provide host and network mobility, dynamical management and auto-configuration in IPv6-based NGN environment? • What new Recommendations are needed to provide QoS support in IPv6-based NGN environment? • What new Recommendations are needed to provide incremental deployment scenarios and strategy towards IPv6-based NGN? • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries?

    • - 26 - TD 569 Question I/13 - Network terminology (Continuation of Q.11/13) 1. Motivation As IP based networks and IP-based applications (e.g. IPTV), ethernet, streaming, ubiquitous networking, etc, gain importance in the industry, there is a growth of new terminology used in the developing standards. ITU-T is increasing its involvement in the related work, particularly in next generation networks, therefore it is reasonable to expect that ITU-T will define its own terminology and elaborate on the definitions of current terminology. In order to establish common language for the industry, in which the ITU plays a key role, it is essential to ensure the extent possible that each concept, architectural element, protocol action, pieces of equipment, etc. is assigned a unique term. For the cases where several such terms have already been defined, it is important to indicate all synonyms pertinent to a particular notion. The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: Y.101, Y.2091 2. Question What is the definition and meaning of the terms used in Recommendations related to existing and evolving networks? Items for study include: • Definitions of concepts, architectural elements, protocol actions, pieces of equipment, etc. that have been identified in the IETF standards-track Requests for Comments (RFCs), ITU-T Recommendations, ISO standards, and normative output of other organizations recognized by ITU-T. • Terms identifying such concepts, architectural elements, protocol actions, pieces of equipment, etc. It is essential to establish consensus on as few terms as possible (preferably, only one term) for a unique notion. • Updating of existing terminology Recommendations (i.e. Recommendations Y.101 and Y.2091) • Produce new terminology Recommendations or other documents as required. • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings? 3. Tasks The resulting terms should be published in new and revised ITU-T Recommendations, which should be re-issued on an on-going basis as the terminology develops. 4.

    • - 27 - TD 569 Question J/13 - Public data networks (continuation of Q.13/13) 1. Motivation As a result of the development of NGN, and the need to support of new services such as IPTV, VPN, new requirements for the Public Data Network have emerged, such as better scalability, throughput, reliability, multipoint to multipoint communication, etc. Various new or enhanced data communication technologies have been developed and deployed in the global market, with the intent of satisfying these new requirements. During the last study period new Recommendations that provide the general requirements (Y.2601) and a high level architecture (Y.2611, technology independent), were developed. These Recommendations will be used to evolve the PDN which provides the topmost part of NGN Transport stratum, to meet the industry requirements for enhanced data communications. This question will continue the studies on data networks and data transmission related to the PDNs, especially the FPBN (based on Y.2601/Y.2611), to provide further details of the key elements of PDN technologies, such as "middle" level architecture (maybe technology dependent), general requirements and methods for naming, routing and addressing from the technical aspect (e.g. format, types), reliability requirements and methods, etc. The objective of this work is to develop a PDN that can efficiently support the NGN packet based services over the transport network that provides connectivity using technologies such as Ethernet, T-MPLS, GFP mapping over SDH/OTN. Work on the Recommendations for data networks has been completed and the Recommendations are currently mature. This set of Recommendations includes much of the work on the leased circuit, circuit-switched, and the X.25 packet-switched public data networks. Systems based on these data network Recommendations have been implemented over a relatively long period of time. Operational experiences in the implementation of those systems may lead to the discovery of technical errors or desirable enhancements to the related Recommendations. Therefore, there is a need for the ongoing maintenance of X-series data network Recommendations. The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: Y.2601, Y.2611, F.600, X.1, X.2, X.3, X.5, X.6, X.7, X.8, X.20, X.20bis, X.21, X.21bis, X.22, X.24, X.25, X.28, X.29, X.30, X.31, X.32, X.33, X.34, X.35, X.37, X.38, X.39, X.4, X.42, X.45, X.46, X.48, X.49, X.60, X.70, X.71, X.75, X.77, X.78, X.80, X.81, X.82, X.92, X.96, X.110, X.111, X.115, X.116, X.121, X.122, X.123, X.124, X.125, X.130, X.131, X.134, X.135, X.136, X.137, X.138, X.139, X.140, X.141, X.150, X.180, X.181, X.300, X.301, X.302, X.305, X.320, X.321, X.322, X.323, X.324, X.325, X.326, X.327, X.328, X.329, X.340, X.350, X.351, X.352, X.353, X.361, X.371. 2. Questions • How can the various aspects of the NGN services including, IPTV, IMS etc. (such QoS, reliability, addressing, routing, naming, security/privacy) be accommodated in the PDN, and how can the PDN best utilize the capabilities provided by the current and evolving transport network to support these NGN services? • How can the various aspects of the NGN services including, IPTV, IMS etc. (such QoS, reliability, addressing, routing, naming, security/privacy) be accommodated in a dedicated data network, and how can that dedicated data network best utilize the capabilities provided by the current and evolving transport network to support these NGN services?

    • - 30 - TD 569 Question K/13 - Packet forwarding and deep packet inspection for multiple services in packet- based networks and NGN environment (Continuation of Question 14/13) 1 Motivation Packet forwarding and DPI (Deep Packet inspection) are essential for multi-service delivery in packet-based networks and NGN environment. It is particularly true when handling Multi-service (e.g. IPTV/VoIP) traffic because these applications have strict requirements on jitter, delay and packet loss rate. The functionalities of DPI and Packet forwarding enhancement can properly identify different type of traffic so as to provide performance guarantees to allow for time-sensitive applications. This question is intended to study the functionalities of Deep Packet Inspection and Multi-service (e.g. IPTV/VoIP) aware identification, lookup, filtering, forwarding and queuing, Multi-service multicast and associated MIBs (Management Information Base) in packet-based networks and NGN environment. It addresses how to make use of these existing bandwidth resources effectively to provide guarantees for multi-service especially time-sensitive, loss-sensitive real-time audio/video data delivery, how to use the control mechanism provided by the current packet-based networks and NGN architecture. 2 Question This Question develops Recommendations with respect to protocols, mechanisms and functionalities for Packet forwarding and Deep Packet Inspection for multiple services in packet- based networks and NGN environment. The associated work will be handled and progressed in co- operation with other relevant study groups, the IETF, IEEE 802 etc. Study items to be considered include, but are not limited to: • The functionalities of DPI and Packet forwarding enhancement. This includes study on flexible and effective DPI mechanisms that allows network devices to look at the packet header and payload in packet-based network and NGN environment. • Multi-service (e.g. IPTV/VoIP) aware identification. This includes the identification filtering, forwarding, classification of the traffic based in a rule database that includes information extracted for the packet header and payload in packet based network and NGN environment. • Node-level forwarding and queuing. This includes ingress lookup, filtering, queuing, metering, priority remark, and delay-aware queue scheduling algorithms. It should guarantee the bandwidth for identified audio and video services from the control mechanism provided by the current packet-based networks and NGN architecture. • Multi-service multicast aspects including multi-service multicast scenarios in NGN environment and optimized multicast mechanisms for video and audio services. • Associated MIBs including definitions on low-level management objects. • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings?

    • - 32 - TD 569 Question L/13 - Security and identity management (Continuation of Question 15/13) 1. Motivation While the public switched telephone networks (PSTNs) that use circuit based technology are relatively secure, security threats on the evolving telecommunications infrastructure are on the increase – both in frequency and in complexity. Efforts over the years to secure packet infrastructures have been somewhat fragmented and event-driven and so far have failed to produce the desired level of protection against threats. This issue is complicated by the large number of organizations working on various aspects of security, making coordination and cooperation difficult and challenging. Recognizing that security is one of the defining features of NGN, it is essential to put in place a set of standards that will guarantee, to the maximum degree possible, the security of the NGN. One example of a new application and architecture, which requires specific and new set of mechanisms is IPTV. A major development that needs detailed standardization is NGN Identity Management. In particular, Study Group 13 needs to address, in the context of NGN, the broad IdM issues of concern to Telecom Network/Service Providers, Governments, and end users. This includes assertion and assurance of entity identities (e.g. user, device, service providers) noted in the following, non-exhaustive list: • Efficient support of subscriber services (e.g. NGN services and applications) using common IdM infrastructure to support multiple applications including inter-network communications • Appropriate secure provisioning of the network devices • Ease of use and single sign-on / sign-off • Public Safety Services • International Emergency and Priority Services • Electronic Government (eGovernment) Services • Privacy/User Control of Personal Information (i.e. Protection of Personal Identifiable Information [PPII]) • Security (e.g. confidence of transactions, protection from Identity (ID) Theft) and protection of NGN infrastructure, resources (services and applications) and end users information • National Security and critical infrastructure protection As NGNs evolve and new security vulnerabilities appear, for which there is no known immediate automatic remedy, such vulnerabilities must be properly documented so as to enable the network administrators and end users to mitigate them. The NGN Security studies must address and develop network architectures that: • Provide for maximal network and end-user resource protection • Allow for highly-distributed intelligence end-to-end • Allow for co-existence of multiple networking technologies • Provide for end-to-end security mechanisms
    • - 33 - TD 569 • Provide for security solutions that apply over multiple administrative domains • Provide for secure Identity Management, which involves, but not limited to: o Reliable authentication of the NGN entities (e.g. users, user devices, network providers, service providers, identity providers, etc.) o Prevention of the unauthorized access to identity data in NGN o Secure exchange of identity information among federated entities in NGN o Support for the record-keeping of the use of identity information in NGN o Support for the user privacy and anonymity in NGN o Capability of supporting the NGN users to securely manage their identity information (e.g. modifying user profiles, changing passwords, enabling location- based services, viewing billing records, etc.) • Provide for security solutions for IPTV that are cost-effective and have acceptable impact on the performance, quality of service, usability, and scalability. The types of protection that IPTV security should provide include, but not limited to: o Content protection o Service protection o Network protection o Terminal protection o Subscriber protection The complexity of the issue necessitates a systematic study of general security mechanisms and applications developed in ITU-T Study Group 17, the lead study group on security, ISO/IEC JTC 1 SC 27, ATIS, 3G Partnerships, IETF, and other applicable SDOs as well as interface and protocol specific mechanisms developed in the relevant ITU-T Study Groups and the IETF working groups.

    • - 36 - TD 569 Question M/13 - Requirements and framework for enabling COTS components in an open environment (Continuation of Question 16/13) 1. Motivation Evolution of current networks to NGNs will occur in a changing environment. However, there is a need to maintain a high level of quality such as that known from legacy telecom networks. Because there is no commonly available term to refer to this level of quality in the context of NGN so far, the term “carrier grade” should be used to refer to this level of quality. In this new environment there are technology trends which include the use of open source operating systems (such as Linux), commoditization of hardware and the availability of Commercial Off-the-Shelf (COTS) components. Additionally, NGN holds the promise of making available mix and match (plug and play) components and enabling services to be developed by third parties. Guidance is required to ensure that COTS components will allow for creation of open and integrated communications platforms consistent with open standards such that they will accelerate deployment of NGN infrastructure and services. It is necessary to define a common approach that helps to navigate through the appropriate interfaces and options to deliver an open and integrated communications platform using these standards. No complete framework exists today to outline and represent relationships with open interfaces and standards required to assemble COTS components across all layers of an NGN solution. A comprehensive component framework that enables the creation of network elements, platforms and applications is needed. Categories of components should be defined to enable the integration of open standards-based off the shelf software intended to operate in hardware and software agnostic architectures. Open standards-based platforms will facilitate advanced solution development and deployment using COTS components from vendors. These components include traditionally- developed commercially available components as well as open source components being integrated into the service provider’s network delivery platforms (such as call control and switching) and simplifying and facilitating the external delivery of new and/or third-party services, content and applications. This framework allows service providers to improve time to market and develop and deliver lower cost enhancements (such as IP Centrex, IP PBX, call servers, etc.) to both customers and third parties. Managing the complexity of the interoperability of multiple vendors products is among the major issues service providers face in transitioning to a next generation infrastructure to deliver new packet-based communications services. The framework should enable service providers to plug and play different COTS components. The ultimate goal of this work is to support the transformation of networks to NGNs through the availability of software components.

    • - 40 - TD 569 Question O/13 – Distributed services networking (DSN) (New Question) 1. Motivation Distributed Service Networking (DSN) can greatly facilitate the provision of current NGN services and new services by using distributed technology. Distributed Services Networking (DSN) has the potential of providing operators with reduced CAPEX/OPEX, improved scalability/ubiquity, self organization/maintenance and fault tolerance capabilities compared to traditional centralized information and communication processes used in current networks This Question will consider how an innovative services architecture, framework and environment deploying distributed computing and networking technology could make the evolving NGN more flexible, reliable and extensible. Distributed technology such as peer to peer (P2P) and mesh technology may be used in managed peer to peer (MP2P) networks to create an overlay network which has an ability to share resources between different nodes and links within a managed network deployment. These networks should have the advantages of self-configuring, self-managing, and self-healing and should result in the provision of service with better performance and lower cost. 2.

    • - 44 - TD 569 Question Q/13 - Service scenarios and deployment models of NGN (Continuation of Question 8/13) 1. Motivation As NGN scope covers wide areas of network, it needs to make simple and clear business deployment models for definition of NGN. Then, a set of promising service scenarios and deployment models of NGN are very useful to accelerate the NGN deployment. All the scenarios should be initiated from the user point of views, which would be described as use cases. NGN capabilities to support various scenarios with end user functions and the third party services could include functionalities for the various types of services with multiple service providers. It is, therefore, currently necessary to standardize NGN capabilities for the realization of convergence services over NGN. Architectures and service scenarios for deployment models of NGN focus on convergence services of ubiquitous network environments. These service scenarios could be designed to enable operators to support key networking environments and build differentiated advantages through business innovation. 2. Question Study items to be considered include, but are not limited to:  From user point of views, application specific NGN service scenarios including all application services and end-user functions. It is pointed out that new application services in NGN stemming from convergence service environments should also be studied.  Technology-based NGN service scenarios by considering computer technology, security technology, electronic appliance technology, broadcast technology including interactive wireless/mobile technology, and telecommunication technology including enterprise and various access technologies.  Architecture of application services are needed to be defined from the viewpoint of NGN scenarios for interaction with the Internet environment such as Web.  What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings? 3.
