  22. Additional Information on Standards Projects ITU-T Seminar – Madrid, December 2002

  23. Accounting rate reform • Transition from accounting rates to cost orientation • to develop general principles and guidelines for the establishment of accounting rates; • to determine cost components to be included in the telephone accounting rates; • to expedite work on developing appropriate costing methodologies; • to establish a transition period to avoid drastic changes, particularly for the developing countries. • Termination charge procedure, allows governments or operators to establish a single charge for terminating traffic in their country, provided the charge meets certain multilaterally agreed criteria. • Settlement rate procedure, allows governments or operators to negotiate cost-orientated and asymmetric settlement rates, better suited to the new market situation. • Commercial arrangement, between countries that have introduced liberalization. Recognized operating agencies will agree bilaterally on the remuneration procedure that is most appropriate to their needs. ITU-T Seminar – Madrid, December 2002

  24. TMN project • TMN related project includes standardization work covering TMN architecture, methodology, common requirements, communication protocols, TMN resource information modeling for generic, switching, V5/VB5 access, transport network view and service management. • TMN standards have to cope with changes in the industry while also satisfying current needs. • TMN Recommendations will result from cooperation with regional and national bodies and industry forums • The specification of information to be exchanged is the essence of TMN. • Requirements need to be understandable to management experts and not necessarily to the modeling experts. • SG 4 work plan addresses IP and to create a TMN framework for the unified management of integrated hybrid circuit-switched (PSTN) and packet-based networks. • The study of TMN requires various expertise and TMN-related Recommendations are being developed in various Study Groups within ITU-T. ITU-T Seminar – Madrid, December 2002

  25. TMN project areas • Architecture • Interface specification methodology • Management services • Management functions (protocol independent) • Management information models and catalogue • Management information registration • Communication protocols • Systems management services and management messages • Conformance requirements • International standard profiles • Terminology • Security ITU-T Seminar – Madrid, December 2002

  26. IPcablecom project • Time-critical interactive services over cable television network using IP-protocol, in particular Voice and Video over IP • Services • Residential/Business IP Telephony • Video IP telephony • Voice/data/video unified messaging • Enhanced conferencing and media services • Entertainment Services • Real-time multiplayer interactive gaming • www.itu.int/itudoc/itu-t/com9/ipcable ITU-T Seminar – Madrid, December 2002

  27. QoS viewpoints There are four viewpoints of QoS that make the definitions and frameworks meaningful and practical for everyone – users, vendors, network operators, service providers etc. ITU-T Seminar – Madrid, December 2002

  28. QoS • The relationship between service and network reliability will be addressed due to the critical need with the rapid deployment of IP-based network and services. • SGs 2, 4, 11, 12, 13 & 16 must make this work converge ITU-T Seminar – Madrid, December 2002

  29. QoS overview • QoS framework/definitions exist (E.800, G.1000), application requirements are well known (G.1010), assessment/monitoring methods well underway • Different approaches to QoS taken by different ITU-T study groups tend to be as follows: SG12 provides the user application requirements; SG13 provides UNI-UNI IP network QoS classes capable of supporting most use applications; SG 16 provides a third-party “agent” control and signaling of QoS using future vertical protocols • NI-NI QoS classes capable of supporting most user applications exist for ATM (I.356) and IP (Y.1541), although new signaling is needed for the IP case • SG 16 has a futuristic QoS Architecture direction to deliver QoS dynamically, over multiple networks ITU-T Seminar – Madrid, December 2002

  30. Global Information Infrastructure • Global Information Infrastructure – a set of 38 Projects to ensure: • Global standards, which are needed because of the globalization of business • Enable users to manage the creation, storage, delivery & use of information • Technological convergence & interconnection of telecommunications equipment with computers • Satisfaction of the new demands on the communications infrastructure by information providers and users • http://www.itu.int/ITU-T/studygroups/com13/gii ITU-T Seminar – Madrid, December 2002

  31. Next Generation Networks • The concept of Global Information Infrastructure (GII) enables people to securely use a set of communication services supporting an open multitude of applications and embracing all modes of information, any time, anywhere, and at an acceptable cost and quality • The term Next Generation Network represent certain technologies, on which the GII concept can be based • The general principles for NGN can be found in various Y‑Series Recommendations. NGN’s are considered to be part of the GII’s “federation of networks” • See:http://www.itu.int/ITU-T/studygroups/com13/ngn2004 ITU-T Seminar – Madrid, December 2002

  32. Access Network Transport project • Based on definitions specified in G.902 • Provides transport bearer capabilities for the provision of telecommunications services inside the AN between a service node interface (SNI) providing customer access to a service node and each of the associated interfaces towards the Customer Premises Network(s) which are being grouped as XNI interfaces (this would include ISDN UNIs) • Comprises transmission media and access NEs entities. • See http://www.itu.int/itudoc/itu-t/com15/ant/ ITU-T Seminar – Madrid, December 2002

  33. Optical Transport Network Technology project • The standards area covered relates to optical transport networks and technologies. The optical transport functions include: • multiplexing • cross connect, including grooming & configuration • management • physical media • An Optical Transport Network (OTN) is composed of a set of Optical Network Elements connected by optical fibre links, able to provide functionality of transport, multiplexing, routing, management, supervision and survivability of optical channels carrying client signals, according to the requirements given in ITU-T Rec. G.872. • See http://www.itu.int/itudoc/itu-t/com15/otn ITU-T Seminar – Madrid, December 2002
