INTUG NGN definition (ITU-T)
• a Next Generation Network is a packet-based network
able to provide telecommunication services, able to make
use of multiple broadband, QoS-enabled transport
technologies and in which service-related functions are
independent from underlying transport-related
technologies.
• it offers unrestricted access by users to different service
providers
• it supports generalised mobility which will allow
consistent and ubiquitous provision of services to users
Source: ITU-T SG 13
INTUG NGN definition (ETSI-TISPAN)
ITU, Geneva - 24 March 2006
www.INTUG.net
• a multi-service, multi-protocol, multi-access,
IP-based network
• secure, reliable and trusted
• an enabler for Service Providers to offer:
– real-time communication services
– peer-to-peer and client-server
– nomadicity and mobility of both users and
devices
– interoperability between legacy and next
generation services and networks
• regulatory compliance (e.g., lawful
interception, number portability and
emergency services)

Interested parties
ITU, Geneva - 24 March 2006
www.INTUG.net
• Operators:
– cost savings
– new services and revenues
– possibility of a new regulatory environment
• Enterprises:
– fast return on investment
– new value-added functionalities
• Consumers:
– lower prices
– life-style choices
– exciting devices and services
ITU, Geneva - 24 March 2006

INTUG
outstanding issues
• continuing power of incumbents
(some have already an NGN like
internal network)
• possible creation of oligopolies
• Long distance and local loop
unbundling
• Multi services networks
ITU, Geneva - 24 March 2006
www.INTUG.net
INTUG
A possible scenario
• access via one single line (broadband)
• using several devices: from the
classical telephone, to TV set, PC,
video and multimedia boxes
• easy access to the Internet at high
speed
• high quality video, general
entertainment
• interactive learning
• new services (to be invented) .....
ITU, Geneva - 24 March 2006

INTUG
A possible scenario
• From the users’ perspective, the
convergence of services will enable the
emergence of the seamless service
concepts, where users can access their
“tailored set” of services from any type
of access network.
• End-to-end QoS is one of the most
important user requirements
ITU, Geneva - 24 March 2006
www.INTUG.net
INTUG
A possible scenario
• connecting inanimate objects to
networks
• networks and networked devices
become ubiquitous
• electronic tags (e.g. RFID) and
sensors extend the communication
and monitoring potential of the
“network of networks”
INTUG
Not simply a new network
• fixed broadband:
ITU, Geneva - 24 March 2006
www.INTUG.net
– corporate
– residential
• wireless broadband networks:
– Wi-Fi
– WiMAX
• cellular voice and data networks
• digital broadcast networks (DAB, DVB,
terrestrial, satellite, handheld)
• (re-)distribution (Wi-Fi and UWB):
– office and residential
– Personal Area Networks (PANs)
– car networks
ITU, Geneva - 24 March 2006

Some technical problems
INTUG for interconnection
• Latency
– the time it takes a bit of data to get
through a network link
• jitter
– the weighted average of the latency
difference between every pair of
consecutive packets received
• jitter particularly affects the performance of
real-time applications such as streaming
video and audio
ITU, Geneva - 24 March 2006
www.INTUG.net
Some technical problems
INTUG for interconnection
• If latency and jitter are tuned by each
Operator in order to supply a good QoS to
their customers, interconnection with other
Operators’ networks may produce poor
overall performance and decrease
dramatically the QoS

INTUG
Loch Lomond Accord
• agreement from 1997-98 between
users and VPN providers
• service management and end-to-end
fault diagnosis and ownership
• administration and billing:
– one stop shopping
– one stop billing
• synchronised private numbering for Onnet to On-net calling
• calling line identification (CLI) and
ringback-when-free
INTUG
Standardisation
ITU, Geneva - 24 March 2006
www.INTUG.net
• very complicated work at:
– ITU SG 13
– ETSI TISPAN
– 3GPP
– etc.
• impossible to assess:
– user needs
– implications of standardisation
• driven by:
– manufacturers
– operators
INTUG
interconnection
ITU, Geneva - 24 March 2006
www.INTUG.net
• well established rules for:
– conventional networks
– IP data networks
• for NGNs interconnection we must refer
to:
– price
– quality of service
– interworking
ITU, Geneva - 24 March 2006
www.INTUG.net
INTUG interoperability
• services must be available on the
networks to which users have access
• devices and networks must interwork
• network selection criteria:
– the cheapest
– the best quality
– security
– reliability
• Administrative and billing implications
INTUG interoperability
ITU, Geneva - 24 March 2006
www.INTUG.net
• relating to network capabilities:
– Network Address Translators and firewalls
– routing tables
– Quality of Service capabilities and
interconnect
– network coverage
– termination capabilities
• related to accessing services and
content:
– unnecessary software and service bundles
– tunnelling
– filtering mechanisms and digital rights
– end-user devices
– content
INTUG interoperability
ITU, Geneva - 24 March 2006
www.INTUG.net
• relating to user information:
– authentication, single log-on and user
profile management
– customer billing information
– access to customer information systems
– resolution of names and numbers through
customer identity systems
– functions for determining location
ITU, Geneva - 24 March 2006

INTUG
conclusion
• NGN: one network paradigm is not
appropriate
• NGN creates complex problems of:
– access
– interconnection
– interoperability
• no clarity about the protection to:
– consumers
– enterprises
ITU, Geneva - 24 March 2006
www.INTUG.net
INTUG
conclusion
For Users, some principle must be
fullfilled:
• Cost orientation
• Widest choice
• Transparency in QoS and tariffs
• Opt-in rule
Users expect a demand driven
mechanism, but, until now, little
evidence of that
INTUG thank you
