Next Generation Networks Initiative

Next Generation Network InitiativeThe European voice for concerted action towards

future developments in Networks

Sathya Rao, Telscom, [email protected], +41 31 3762033


• A consortium of representatives from leading industries, operators and academia

• The first European open environment for strategic discussions on topics & issues of NGN.

• A Project of the IST programme

Mission

• Facilitate and support smooth evolution of and transition to next generation networks

• Resolve issues that create barriers for NGN deployment

• Encourage clustering of activities• Create open environment for discussions

on trends of technology• Create awareness among the actors


Objectives

• Assess the technologies and their significance for NGN

• Achieve interoperability for seamless services through harmonised standards

• Achieve compatibility and essential commonality between solutions and products

• Identify new opportunities e.g. for convergence etc.


Topics

• Internet infrastructure• Mobile and Wireless• Optical Networks• Home Networks• Edge Devices• Network Management• Interworking, Interoperability

– further topics may be added later


NGN-I : Why ????

• With many existing fora, groups, organisations, what does NGN-I contribute?

• NGN-I is adding value by– being a network for strategic discussions at an early

stage of new technologies– acting as an enabler and facilitator by liaising with

existing international organisations– focussing on selected issues & topics of strategic

importance (Technology Roadmaps, Benchmarking)– expediting standardisation processes


Networked Society

IP

• Different types of network infrastructures are linked through common protocol

• All communication will be based on packets running on circuit, packet and wireless networks

• There will be convergence at service level to reach any one from anywhere at any time


NGN Applications Requirement


Technologies and Services Convergence


R/Evolution vs. User demand


Networking Technologies


NGN Requirements-IPv6

• Requirements– Scalability of networks with address space,QoS and

security, which are basic features of IPv6 networks– Connectivity with existing IPv4 networks is necessary– IPv6 should happen from the edges, not from the core.– Applications are important for pushing IPv6

• it has to be transparent to the end user– Interoperability with IPv4 has a cost

• 100% interoperability is not always necessary– We need a credible transition story.

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 • 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


Next Generation Networks International and European

Initiatives


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


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.

• www.3gpp.org


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


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


Expected Results

• Co-ordinated / collective contributions to standards

• Technology Benchmarking• Technology Roadmaps• Collective awareness

– results are open


Membership of NGN-I

• NGN-I Membership• Any organisation (world-wide) active

in the field of NGN can join NGN-I

• Members can take an active role in the NGN development and part of their work can be paid


How does NGN-I operate ?• Topic oriented:

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
