5Evolution 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
6Dense Wavelength-Division Multiplexing (DWDM)
7DWDM 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

9Intelligent 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!
10Next Generation Networks International
Initiatives
11IETF 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
123GPP 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. - www.3gpp.org
13Internet 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
14 IPv6 testing backbone network
15CANARIE 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
16European 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)

20 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
21Conclusions
- 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
