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
Lucent TechnologiesLucent TechnologiesBell Labs InnovationsBell Labs Innovations
• 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
Lucent TechnologiesLucent TechnologiesBell Labs InnovationsBell Labs Innovations
• 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

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.
