Status of several projects• User projects: IPv6 Cluster represents number of projects addressing

IPv6 technologies:– NGNLAB: Testbed for IPv6 applications, systems and functionalities

across wide area network: represents a user– 6WINIT: addresses Wireless internet using IPv6 and developing

applications trials across fixed and mobile networks.– LONG: Addresses IPv6 transition and access networks to test IPv6

features. Also addresses porting of IPv4 applications to IPv6– MIND: mobile networks with handover functionality between WLAN and

WAN with IPv6 functionalities. Both micromobility and macro-mobility are addressed.

– Mobydick: IPv6 mobile network with QoS, AAA and charging– WINE, WINEGLASS, GCAP, DRIVE etc…: Just concluded projects

which addressed different functionalities of IPv6 and demonstrated the functionalities

Backbone networks• GEANT: Pan-European Gigabit network, expected to

support IPv6• 6NET: Academic IPv6 network, about to announce the

deployment of IPv6 native network• Euro6IX: Commercial operators involved IST projects for

pre-commercial native IPv6 deployment– All the 3 projects and some national projects are ready to support

IPv6 , but– Where are the users ? And what are their expectation ?– Real deployment needs the user expectation to be met with an easy

access to IPv6 network

IPv6 features • All desirable features have been included and demonstrated

by different projects– Scalability: 128 bits addressing, Static IP address allocation on

demand, peer-to-peer and secure communication– QoS: Both Diffserv and Intserv support– Multicast, unicast, anycast,.. All are possible– Security is an obligatory function: Is it possible to provision global

security feature or to better to think of distributed host level security !– Autoconfiguration, Multihoming – Many data applications are available but not interoperability– Many Audio,video and MM applications are also demonstrated

Users and Issues• Who are the users ?

• Home, SoHo, SMEs and corporate networks are real users• ISPs: They are responsible to provide the access to IPv6 networks. No ISP

supports IPv6 commercially today• Home user would be the best user to test the pilot applications and features, but

needs an access without cost during the trial period. Is it feasible ?

• Networking issues:• Addressing plan still not finalised, all experiments are on adhoc basis.• Functionalities are demonstratable in a research network environment only• No stable applications support, No seamless services across IPv4 and IPv6• DNS and DHCP issues of IPv6 are still in discussion • No ISP support, • QoS, security and privacy, plug and play, interoperability across several media

networks (fixed, mobile in and outside the home environment)

User expectations of IPv6 backbone• IPv6 backbone network should have full functionality to guarantee

end-to-end features, since Internet has no core network and routing is unpredictable

• Addressing scheme well defined• Interoperability with legacy networks• Terminals with built-in IPv6 stack and supporting common

applications of interest with seamless interworking with IPv4• High bandwidth Access networks with edge devices supporting IPv6• Autoconfiguration and simple operational management• QoS, Security features built into both edge and core networks for end-

to-end performance• Roaming for GPRS (UMTS) and static IPs when needed for tunnelling

purposes
