Come back to originCome back to origin• IP was designed to allow end-to-end data

transfers Whatever the transmission technologyOffering a global addressing schemeImplementing simple protocols and mechanisms

Today RealityToday Reality• Do you have an Internet IP address?

May be you got one if you have a permanent broadband access!

• Do you think you can call anyone connected to Internet? What you can easily do is to send/receive a file to/from a

server, that’s all!

P2P protocols are not so simple!P2P protocols are not so simple!

• NAT has been added to extend addressing capacity Need to learn the address “outside the NAT” Provide this address to peer Need either NAT-aware application or application-aware NAT May need a third party registration server to facilitate finding peers

Multiparty transfers too Multiparty transfers too complicated to be deployed complicated to be deployed

• With NAT, complex and brittle software 2 addresses, inside and outside P1 provides “inside address” to P3, “outside address” to P2 Need to recognize inside, outside P1 does not know outside address of P3 to inform P2

IPv4 address spaceIPv4 address space• IPv4 addresses coded on 32 bits

4.3 billion addresses available… in theoryAddresses are structured => a smaller number is usable (around

250 million, 40 % currently available… )Much less than the current human population

• IPv4 addresses allocated by Registries using severe policiesDifficult to get the number of addresses requiredThe shortage already exists

IPv4 routingIPv4 routing• Addresses scarcity and multi-homing leads to

un-aggregatable address assignmentsA lot of entries in routing tables : currently reaching

120.000 Heavy burden for routers => instability…

IPv6 Addressing & SecurityIPv6 Addressing & Security• No more address translation (NAT)

The end of the switchboard!Use of “stable” global addresses

• Keep the notion of private addresses

• Multiple addresses per deviceGlobal and local ones

The 6WINIT ProjectThe 6WINIT Project• Pilots clinical and other IPv6 applications

over wireless networksUses GPRS, WLAN and later UMTS Initial GPRS not IPv6-enabled, WLAN is, UMTS

not available yetConcerned with media and data applications

• Concerned to make all components IPv6-enabled – but treats also transition

• Includes Japanese, Korean partners and Polish partners

Project Support & InfrastructureProject Support & Infrastructure• Project around 3.5 Euro of EC money

– 7 MEuro over 2 years • Uses IPv6 base networks

6NET/GEANT is the network of choice• Has 16 partners in ten countries• Trying to bridge gap between 3GPP and

the IETF• Putting up real systems demonstrators

Using GEANT as connecting network so far

Deployment stepsDeployment steps• Products are available today

SW & HW• Numerous legacy applications are running on v6,

others are arriving• IPv6 is progressively integrated in network

architecturesWith the goal to provide value added services

• IPv6 will progressively arrive in corporations and houses with the new OS versions and applications

How to introduce IPv6 (1)How to introduce IPv6 (1)• By providing seamless IPv4 and IPv6

broadband servicesThe IP version migration must be transparent to the user

• ISPs have to progressively deploy access and edge routers able to run both versions Allow to progressively modify the ISP infrastructure

• By offering customized services Needs arrive with the applicationsCustomers have different constraints

Security, reliability, investments, operational requirements…

• At the right speedLet’s invest when necessaryBut start now to deploy a pilot platform to be able to build

a clear transition roadmap!

ConclusionConclusion• IPv6 is now a reality• IPv6 is the only possible solution if we want to deploy billions of

fixed and wireless terminals• All IP networks will have to move• The new IPv6 infrastructure allows the deployment of new

applications based on peer-to-peer and the push models• With IPv6, the use of the network becomes simpler• The first step for Telcos/ISPs is to provide IPv4/v6 broadband

services on fix and wireless access networks

• Start now and take a leading position!
