  3. Why NGN? The NGN concept takes into consideration new realities in the telecommunication industry characterized by factors such as: the need to converge and optimizethe operating networks and the extraordinary expansion of digital traffic (i.e., increasing demand for new multimedia services, increasing demand for mobility, etc.).

  4. Background: ITU-T’s NGN Work In July 2003, the Joint Rapporteur Group on NGN (JRG-NGN) was established in SG13 to study NGN requirements, the general reference model, functional requirements and architecture of the NGN, and evolution to NGN. In June 2004,the JRG-NGN produced two Recs. Y.2001; General overview of NGN and Y. 2011; General principles and ref. model for NGN, and a Focus Group on NGN (FGNGN) was formed to accerelate NGN activities initiated by JRG-NGN. In November 2005, the FGNGN provided a scope of NGN Release 1 and its mandate was extended.

  5. NGN Global Standards Initiative • Now this NGN work is carried forward by ITU-T’s NGN-Global Standards Initiative (NGN-GSI) to encompass all NGN work across ITU-T SGs and to provide the global standards of NGN. • NGN-GSI Objectives and Goals: • to address the market needs for NGN standards, • to produce global standards for NGN, • to further strengthen the ITU-T’s leading role amongst the groups in NGN standard work, • to keep visibility of the work spread between different technical groups in ITU-T.

  6. NGN Study Topics • ITU-T activities are related to the establishment of architectures, interface specifications, and implementation guidelines in the form of ITU-T Recommendations for the realization of NGN. • NGN study topics include; • Evolution of existing networks to NGN • QoS (Quality of Service) for NGN • Interoperability between different sys. & NWs • Security issues in architecture, QoS, NW management, mobility, charging and payment • Generalized Mobility • Service Capabilities and Architecture

  7. NGN Release 1 at July 2006

  9. Rec. Y.2001 defines NGN as“Apacket-based networkable to provide telecommunication services and able to make use ofmultiple broadband, QoS-enabled transport technologies, and in which service-related functions areindependent fromunderlying transport-related technologies. It enablesunfettered accessfor users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.” Definition of NGN and the Transport Broadband Access solutions to support NGN services ADSL, VDSL, B-PON, G-PON, HomePNA Transport networks to support Packet-based network. SDH, OTN, GFP, MPLS, Ethernet networking

  13. Optical and other transport network infrastructure Focal point in ITU-T is for the development of standards on optical and other transport network infrastructures, systems, equipment, optical fibers, and the corresponding control plane technologies to enable the evolution toward intelligent transport networks. This encompasses the development of related standards for the customer premises, access, metropolitan and long haul sections of communication networks.
