Study Group 13 mandateStudy Group 13 mandate• Multi-protocol and IP-based networks and their

internetworking

• Responsible for studies relating to internetworking of heterogeneous networks encompassing multiple domains, multiple protocols and innovative technologies with a goal to deliver high-quality, reliable networking. Specific aspects are architecture, interworking and adaptation, end-to-end considerations, routing and requirements for transport.


MissionMission

• To provide a focal point in ITU for technology-independent network architecture and long-term evolution studies, including IP-network studies, through development of the necessary frameworks and architectures, coordination with the various related studies in the other ITU Study Groups and collaboration with other standards bodies.


• To help ITU-T continue to respond to the changes to studies and priorities necessary to integrate traditional telecommunication networks with IP-based networks in order to provide full integration of services and applications to end users. Also, to give network providers the tools and information to support the market-driven changes to the telecommunication industry.


• To conduct IP-related studies focusing on

network architecture, network capabilities,

network evolution, service and

performance aspects, and access

arrangements to achieve interoperability in

the multi-vendor and multi-network-

operator environments.


Particular areas of study key to this evolution are IP-based network architectures, IP-based network performance, IP transfer capabilities, IP-VPN (virtual private network) services, IP-based network resource management and access arrangements.


• To conduct the remaining studies in the area of B-ISDN resource management, performance and the ATM Layer and its adaptation and interworking.

• To encourage harmonisation of IP-related and GII studies across the ITU-T study groups through the evolution and further development of the ITU-T IP and GII projects.


• To collaborate with other

standardisation bodies in identifying

gaps in the standardisation programmes

concerning IP networking and to

develop proposals and

Recommendations to advance the

necessary work.

GII AspectsGII Aspects

• The objectives of the GII

• Driving forces, trends and directions

• The role of the ITU

• The current situation


GII ObjectivesGII Objectives

The GII must be designed to:• enable information providers and users (e.g.

individuals, information users, information providers, and information service providers) to communicate securely with each other any time and anywhere at acceptable cost and with acceptable quality


• provide a set of communication services

• support a multitude of open applications

• embrace all forms of information and

information generation (audio, text, data,

image, video, etc.) and of its use and

transportation

• operate in a transparent, user-friendly and straightforward way


• provide seamless, interconnected and

interoperable communication networks,

information processing equipment, data-

bases and terminals (including TV-sets)

• enable competition between the players in

the information and telecommunications

(including broadcasting) sectors


Driving ForcesDriving Forces• the convergence of technologies in use

within telecommunications, computers, consumer electronics and the move of content provision industries towards digital technology

• the new business opportunities, created by the unbundling of services made possible or necessary by deregulation, and other commercial and/or open market pressures


TeledensityTeledensity

• Industrialised countries - 48 (18)

• Middle income countries - 10 (2.3)

• Least developed countries - 1.5 (0.01)

• World average - 11.5

– (PCs per 100 inhabitants)


Trends and DirectionsTrends and Directions

• The GII will not, initially, require or employ new network capabilities, but will define how a multiplicity of existing capabilities will interwork in the context of a "federation of networks". However, standardisation activities related to the GII must permit new network capabilities and technologies to be introduced.

The role of the ITUThe role of the ITU• The goal of the ITU is to play a "catalytic

role" in facilitating the development of truly

global information infrastructures through

its work on standardisation, by offering a

platform for discussions of a general

regulatory framework and as a link

between developed and developing

countries.

Contents - IP AspectsContents - IP Aspects

• Background

• ITU actions

• The ITU-T IP Project

• Future plans


IP AspectsIP Aspects

• Explosive growth of IP based networks

• Data traffic growing ten times faster

than voice traffic

• In near future will account for over 80%

of all traffic on telecomms networks

• Business directions are changing


• Shorter development cycles

• Shorter life cycles for services and

products

• Standards bodies must be able to

respond


• Interoperability of IP and telecomms networks and of their services is of major concern

• IP-based services are required with the speed, capacity, ease of use, reliability and integrity that has been associated with the world wide public telephone network


ITU-T ActionsITU-T Actions

• Study Group 13 appointed as Lead Study Group for IP related aspects

• Guidelines for collaboration with the

ISOC/IETF prepared by TSAG including:

– how to interact on work items– representation– document sharing


• All ITU-T Study Groups actioned to

review their Questions to determine

how best to address the development of

standards for IP-based networks in their

specific area of responsibility


• IP-based networks were recognised as a key strategic area for the ITU by the October 1998 ITU Plenipotentiary Conference

• Two Resolutions were passed concerning:– involvement in ICANN

– strategic review of ITU IP related studies


The ITU-T IP ProjectThe ITU-T IP Project• In its capacity as ‘Lead Study Group for

IP related studies’ Study Group 13 has

developed an ‘ITU-T IP Project’ which:

– is separate from, but closely related to GII

studies

– is intended to encompass all related ITU-T

work
