Evolution of Transmission Technology – 1 st Generation: Copper is transmission medium – 2 nd Generation: Optical Fiber (late 80 s) • 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 – 3 rd Generation: Intelligent optical networking (1999) • Routing and signaling for optical paths ITU workshop: Transition towards Next Generation Networks

Dense Wavelength-Division Multiplexing (DWDM) ITU workshop: Transition towards Next Generation Networks

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 ITU workshop: Transition towards Next Generation Networks

Optical Pass-Through (Routing) Node A IP/ATM/ SDH Node B IP/ATM/ SDH Node C IP/ATM/ SDH No optical pass-through Node A IP/ATM/ SDH Node B IP/ATM/ SDH Node C IP/ATM/ SDH With optical pass-through ITU workshop: Transition towards Next Generation Networks

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 ITU workshop: Transition towards Next Generation Networks

IETF: IP Next Generation • Main issue: transition from IPv 4 to IPv 6 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 • IPv 6 Forum (http: //www. IPv 6 forum. com) – Associated to IETF, founded in Europe to promote IPv 6 among industry partners for smooth transition ITU workshop: Transition towards Next Generation Networks

3 GPP: Third Generation Partnership Project • 3 GPP will provide globally applicable Technical Specifications for a 3 rd 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 3 GPP are working together for the successful introduction and development of UMTS/IMT-2000 ’’third generation’’ mobile communications systems. • www. 3 gpp. org ITU workshop: Transition towards Next Generation Networks

Internet 2 • Develop and deploy advanced network applications and technologies, accelerating the creation of tomorrow’s Internet – Enable new generation of applications – Re-create leading edge R&E network capability – Transfer technology and experience to the global production Internet • Focus Areas – Advanced Applications – Middleware – Advanced Network Infrastructure – New Network Capabilities – Partnerships ITU workshop: Transition towards Next Generation Networks

IPv 6 testing backbone network ITU workshop: Transition towards Next Generation Networks

CANARIE Inc: Canadian Initiative MISSION • To facilitate the development of Canada’s 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 $300 m (1993 -99) • total project costs estimated over $600 M • currently over 140 members; 21 Board members ITU workshop: Transition towards Next Generation Networks

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) ITU workshop: Transition towards Next Generation 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 ITU workshop: Transition towards Next Generation Networks

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 (IPv 6, 3 G 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 ITU workshop: Transition towards Next Generation Networks
