Additional Information on Standards Projects
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.

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.

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.
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

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

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

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. NGNs are
  considered to be part of the GIIs federation of
  networks
• Seehttp//www.itu.int/ITU-T/studygroups/com13/ng
  n2004

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/

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.
