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.
