    • 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.
  • the settlement rate procedure, allows them 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.

tmn project
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.

global information infrastructure
Global Information Infrastructure

    • 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 – Kasane, July 2002

qos overview
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 – Kasane, July 2002

qos viewpoints
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 – Kasane, July 2002

slide18
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
