GII 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 Technologies
Bell 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 Technologies
Bell 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

IP 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
Lucent Technologies
Bell Labs Innovations
• Shorter development cycles
• Shorter life cycles for services and
products
• Standards bodies must be able to
respond
Lucent Technologies
Bell Labs Innovations
• 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

The 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
Lucent Technologies

Project Areas
• Area 1 - Integrated architecture
• Area 2 - Impact to telecommunications
access infrastructures of access to IP
applications
• Area 3 - Interworking between IP based
network and switched-circuit networks,
including wireless based networks
Lucent Technologies
Bell Labs Innovations
• Area 4 - Multimedia applications over IP
signals
• Area 5 - Numbering and addressing
• Area 6 - Transport for IP-structured
signals
• Area 7 - Signalling support, IN and
routing for services on IP-based
networks
• Area 8 - Performance
Lucent Technologies
Bell Labs Innovations
• Area 9 - Integrated management of
telecom and IP-based networks
• Area 10 - Security aspects
• Area 11 - Network capabilities including
requirements for resource management
• Area 12 - Operations and Maintenance
(OAM) for IP

Rec X.509
Information technology – Open Systems
Interconnection – The Directory: Authentication
framework
• Issued jointly with the ISO
• Version 6 currently being worked on, target 2001
• Amendments provide extensions to the Directory
to support enhancements for public key certificate
and attribute certificate framework extensions and
certificate revocation.

GII Project M3
Technical Framework for Electronic
Commerce
• the support of standardized transactions, i.e.
presentation of the offer, navigation and selection
• the exchange of commercial documents such as
orders, invoices, contracts
• the support of delivery, especially with regard to
electronic goods
• a high level of security
• means for the support of payments
Lucent Technologies
Bell Labs Innovations
Pointers to new standards
requirements
• Much of the current debate is not about
standards but the security environment and
administrative / regulatory issues
• Many of the necessary standards are in
place or are being enhanced but further
extensions could be considered to support
and / or enable further harmonisation of
authentication technologies
Lucent Technologies
Bell Labs Innovations
Possible areas for further
standards work
• Additional information fields in Rec
X.509?
• Addition of generic attributes plus
various extensions for different
contracts etc?
• Extensibility profiles?
• Others?
