ITU-T
What is the
next generation optical network?
(different targets different timescales)
o Extension to current SDH/SONET
network with ASON, GMPLS, etc. ?
o Bitrate and protocol transparent optical
datapath with electrical control and
management ?
o All-optical network with optical control,
information processing and routing ?

ITU-T
Why do we need the
next generation optical network ?
o Cost reduction potential larger for optics than
for electronics
o Increased network efficiency and utilisation
o Increased flexibility and responsiveness to
dynamic traffic demands/changes
o An optical network is in line with the MPLS
concept (simplified core, complex and
intelligent edges)

What is needed for the next
ITU-T generation of photonic networks
to become a reality
o Significant effort needed to lower the cost
and enable OAM functions of optical
components
o Better understanding of traffic and
performance issues needed to evaluate cost
and reliability in current proposals.
o Optical networks must become digital
o Gain consensus on administrative concepts
and standards.

When will the next generation of
photonic networks become a
ITU-T
reality
o Dynamic administration of pseudo
optical networks (SONET/SDH) in 2-4
years.
o All-optical networks functions in the
data plane obtainable in 5-10 years
o All-optical operation in all layers is not
realistic with current know technology
(and might never be)

European cable situation
ITU-T
9-10 July 2003
o Weak standardisation position
(proeminence of US standards); has led to
local vendors bankrupcy; few projects
o Pro-active association (ECCA), grouping
main operators; TComLabs for
interoperability
o Tendency to recomposition towards a few
main players (Pan-European operators)
o Weak economical situation but good
potential (broadband access, voice, DTV);
target 50% of broadband access market

HFC networks SWOT
o Strengths:
• Flexible capacity
ITU-T
• Evolution to wireless/FTTH
• Allows triple-play services
o Weakness:
• Upgrade cost and delay
• MSOs financial situation / legacy situation
o Opportunities:
• Integration of video and multicast
• Added value services
o Threats:
• ADSL with H264 / Satellite with PVR
• Cooperating networks
9-10 July 2003
Workshop on Next Generation Networks: What, When & How?
14
Trends
ITU-T o Fast bidirectional upgrade
o No strong push for DTV
o Strong deployment of broadband data access;
may drive to global IP infrastructure
o VoIP systems deployment (slower than
expected)
o Video (VoD) related services expected to
deploy rapidly
o Home network extensions: interface with HN,
security in the home

Broadband for All
General Considerations
ITU-T
o Policy: Broadband For All is the cornerstone of
eEurope 2005 Action Plan, IPv6 and PLC policies.
Linked to Regional Policy, Space Policy, and Telecom
Regulatory Framework.
o Links to National Initiatives: Eureka CELTIC, PUA,
ERASME and CNRS of F, KOMNET and NanOp of D,
UKCPO), in line with the ERA concepts.
o Third Countries: (notably:) Russia, Brazil, Japan.
