Introduction

o Much more advanced mobile services• Adaptive and self-configuring services, context

aware services...o Numerous wireless access networks

• WLAN (802.11x), WPAN (802.15), MBWAN (802.16, 802.20), or 3G WWAN…

• Dedicated or generic purposeso More diverse mobile computers/terminals

• Smart-phones, PDAs, laptops, tablet, PCs…• Specialized Hardwares (mobile routers)• Various type of sensors and cameras

2


Is IPv6 necessary?

o Number of node involved • 2,5 billions of mobiles and much more devices • 600 millions of cars, 3 billions expected by 2050

o Network diversity• IP works over everything

o Stakeholders multiplicity• IPv4 would constrain the relation

o Different time scale (innovation and support)• tens of year automotive industry• few years in telecommunications• months in services

3G RAN

Each mobile does

not manage

mobility, it is just

an IP terminal

Only the router

has to reach the

devices and mobile router

Each mobile

needs only one

wireless interface

Network Router could manage

Is network mobility management necessary?

✓ Host mobility (MIP on teminal)

✓ Network mobility (on a router)

o Adaptive applications support in NEMO• Distributed vs.

centralized o Smart routing decision

• Operator policies support

• Context awareness• User preferences


Conclusion & perspectives

o Current ITS market• Communications

—Different proprietary solutions/communication systems—Open the market to reduce the cost and free the innovation

o IPv6 is not just an option for wide deployment• IPv4 would limit the development of an ecosystem

—Service and connectivity providers would be bind together

o ISO defines the CALM architecture• Use IETF open standards (IPv6, NEMO)

o Multiple ITS stakeholders have to take part in the decision making• routing decision, interfaces management

When beginning to work with IPv6?

o Now !• Strong incentives from EC to move to IPv6 in research project

and in deploymento IPv4 address space exhaustion date has been recently revised

• IANA count down has been set to January 2011— http://www.potaroo.net/tools/ipv4/— http://xkcd.com/c195.html

— http://www.arin.net/statistics/statistics.pdf— http://www.arin.net/announcements/20070521.html

o Deployment and ITS related development• Do consider IPv6 in the early stage of the design • Large testbed and operational IPv6 network are available

• IPv6-only services could start very fast• All new application development should be IPv6 compliant

http://www.arin.net/annoucements/20070521.html

o French academics have been involved in the IETF specifications since the very beginning• INRIA has developed the first IPv6 stack

o G6• Association set up 10 years ago to ease IPv6 deployment between

universities• IPv6 is fully operational within RENATER• IPv6 training (tutorial)

• IPv6 book (in French)

o IPv6 task force France• Launched at the Sénat in September 2002

• Part of the G6 since 2007: http://www.g6.asso.fr/tff• Still not enough involvement from the industry
