1 Next Generation Networks Convergence, evolution and roadmaps Dr. Sathya Rao,Telscom Consulting, Berne
2 NGN Applications Requirement
3 IP Everywhere The Internet Protocol is becoming pervasive but it was designed over 20 years ago More and more devices are using IP and they require reachability places a demand on IP address space 1 billion IP devices by 2003 requires IP routing to be scalable IP is a convergence protocol for the evolution of next generation networks
4 Internet - the way forward Internet today Millions of users Web, , low-quality audio & video Applications adapt to underlying technology Next Generation Network of tomorrow Billions of users and devices Convergence of applications and services New technologies lead to novel applications Building a real information society with Alwayson Network Global village a reality
5 Internet Growth Current estimates 300M users online worldwide, US/Europe-centric 70M hosts connected with global IP addresses Most of these are with fixed network Growth of Mobile internet WAP, GPRS, EDGE, UMTS,.. With data services Limitations of IPv4 with 32-bit addressing allows 4B hosts but allocation has been done inefficiently some institutions own a Class A address space CIDR and NAT have only patched the problems
6 Networked Society Different types of network infrastructures are linked through common protocol IP 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
7 Fixed vs. mobile access Subscriptions worldwide (millions) Fixed Telecom subscribers Fixed Internet subscribers Basic Mobile Mobile Multimedia Source: UMTS
8 Mobile Internet will be always-on Sessions / Month / GSM sub (leading markets) Usage Fixed Fixed WWW WWW Mobile Mobile WWW WWW (WAP) (WAP) WAP GPRS IPv6
9 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.
10 3GPP standards status Issues addressed in 3GPP Rel 5 type network i.e. fast radio via UTRAN, separation of PS and IM domains and addresses: IP address allocation Header compression with security Interworking with IPv4 network SIP VoIP (and possible multimedia) QoS DNS Interworking of PS and IM domains Roaming Time to setup GTP tunnels Etc
11 Moving towards IPv6... Moving towards IPv6 is both a near-term and a long -term concern of network dependent businesses equipment manufacturers network owners service providers and public authorities, such as the EC. For Europe, it is at the same time a challenge and an opportunity

13 Technologies and Services Convergence
14 R/Evolution vs. User demand
15 Networking Technologies
16 IP,ATM, Optical Technologies Access Core
17 Evolution of Transmission Technology 1st Generation: Copper is transmission medium 2 nd 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 3 rd Generation: Intelligent optical networking (1999) Routing and signaling for optical paths
18 Dense Wavelength-Division Multiplexing (DWDM) N - - -
19 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
20 Optical Pass-Through (Routing) Node A Node B Node C Node A Node B Node C IP/ATM/ SDH IP/ATM/ SDH IP/ATM/ SDH IP/ATM/ SDH IP/ATM/ SDH IP/ATM/ SDH No optical pass-through With optical pass-through
21 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!
22 Next Generation Networks International Initiatives
23 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 IPv6 Forum ( Associated to IETF, founded in Europe to promote IPv6 among industry partners for smooth transition
24 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.
25 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
26 IPv6 testing backbone network
27 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 $300m ( ) total project costs estimated over $600 M currently over 140 members; 21 Board members
28 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)
29 TEN-155/GEANT Network
30 European experiments: Telia Example Services + Businesses Telephony, VoD, IP-VPN Audio/video, broadcast, e-commerce WWW, File transfer, Games, On-line shopping, , etc IP Transport and service network independent communication protocol Services Networks IP based broadband access PSTN/ISDN, MPLS, IP-net, etc Optical network (DWDM)
31 Telia Experiment The IP-Plug is the next generation communicationsplug for both Ring and Web-tone Customer equipment/home LAN Ethernet 10 -> 100 -> >. Mbit/s
32 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
33 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
