Evolution of Transmission Technology
  • 1st Generation Copper is transmission medium
  • 2nd Generation Optical Fiber (late 80s)
  • Higher data rates longer link lengths
  • Dense Wavelength-Division Multiplexing (DWDM,
    1994)
  • Fiber exhaust forces DWDM
  • Erbium-doped fiber amplifiers (EDFAs) lower DWDM
    transmission cost
  • 3rd Generation Intelligent optical networking
    (1999)
  • Routing and signaling for optical paths

DWDM Evolution
  • Faster (higher speed per wave),
  • 40 Gb/s on the horizon
  • Thicker (more waves),
  • 160 waves possible today
  • Longer (link lengths before regeneration)
  • A few thousand km possible today
  • 160 waves at 10 Gb/s 1.6 Tb/s
  • 25 million simultaneous phone calls
  • 5 million books per minute

Intelligent Optical Networking
  • Optics is not merely a transmission technology
  • Optics provides a flexible layer upon which to
    deliver network service
  • DWDM provides enormous link capacities
  • DWDM Physical layer of Intelligent Optical
    Network
  • Routing and signaling of optical paths
  • Provides significant economies over conventional
    network architectures
  • Enables revolutionary new services
  • 2.5 Gb/s path from anywhere to anywhere, on
    demand!

Next Generation Networks International
Initiatives
11
IETF IP Next Generation
  • Main issue transition from IPv4 to IPv6
    technology
  • Expanded Routing and Addressing Capabilities
  • Header Format Simplification
  • Improved Support for Options
  • Quality-of-Service Capabilities
  • Authentication and Privacy Capabilities
  • Autoconfiguration
  • Multihoming
  • http//www.ietf.org
  • IPv6 Forum (http//www.IPv6forum.com)
  • Associated to IETF, founded in Europe to promote
    IPv6 among industry partners for smooth transition

12
3GPP Third Generation Partnership Project
  • 3GPP will provide globally applicable Technical
    Specifications for a 3rd Generation Mobile System
    based on the evolved GSM core network, and the
    Universal Terrestrial Radio Access (UTRA), to be
    transposed by relevant standardization bodies
    (Organizational Partners) into appropriate
    deliverables (e.g., standards).
  • UMTS Forum and 3GPP are working together for the
    successful introduction and development of
    UMTS/IMT-2000 third generation mobile
    communications systems.

13
Internet 2
  • Develop and deploy advanced network applications
    and technologies, accelerating the creation of
    tomorrows Internet
  • Enable new generation of applications
  • Re-create leading edge RE network capability
  • Transfer technology and experience to the global
    production Internet
  • Focus Areas
  • Advanced Applications
  • Middleware
  • Advanced Network Infrastructure
  • New Network Capabilities
  • Partnerships

CANARIE Inc Canadian Initiative
  • MISSION
  • To facilitate the development of Canadas
    communications infrastructure and stimulate next
    generation products, applications and services
  • Canadian equivalent to Internet 2 and NGI
  • private-sector led, not-for-profit consortium
  • consortium formed 1993
  • federal funding of 300m (1993-99)
  • total project costs estimated over 600 M
  • currently over 140 members 21 Board members

16
European Initiatives
  • DANTE pan-European network to interconnect the
    European National Research Networks SURFNET
    (NL), JANET (UK), WIN (G), SWITCH (CH), RENATER
    (F)
  • DANTE's European dimension
  • TEN-155 Network (Quantum)
  • Q-MED TEN-155 network interconnection with
    national research networks of Israel and Cyprus
  • GEANT (follow-up of TEN-155 towards multi Gigabit
    core network interconnecting national research
    networks)

Next Generation Network Initiative
  • A European IST project to promote the converging
    next generation networking technologies
  • A group of IST projects representatives would
    work towards an international co-operative work
    through developing roadmaps, benchmark reports
    and well established links to international
    research groups.
  • Will establish different focus topical groups
  • Will manage a central secretariat
  • Will provide links to research projects
  • promotes the contribution to standards groups

21
Conclusions
  • NGN initiative launched to study innovative NGN
    R/Evolution
  • Networks will have variety of access and core
    networks to serve the society
  • Interworking and interoperability would be major
    issues
  • NGN (IPv6, 3G and WDM) would be widely deployed
    to provide broadband, high quality and secure
    services
  • New communication software will drive the
    evolution with differentiated value added
    services
  • Standards play a key role in NGN vision
