6W02/ Unlocking the Services Potential of IP Networks through IPv6 Patrick COCQUET, 6WIND Chairman, IPv6 Forum Vice President TeleBalt conference, October 2002

6W02/ Why IPv6 ?

6W02/ Come back to origin IP was designed to allow end-to-end data transfers Whatever the transmission technology Offering a global addressing scheme Implementing simple protocols and mechanisms

6W02/ Today 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!

6W02/ 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 LAN Internet P1 NAT LAN P2 NAT

6W02/ Multiparty transfers too 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 P1P2 P3 Home LAN Internet NAT NAT

6W02/ IPv4 address space IPv4 addresses coded on 32 bits 4.3 billion addresses available… in theory Addresses 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 policies Difficult to get the number of addresses required The shortage already exists

6W02/ IPv4 routing Addresses scarcity and multi-homing leads to un-aggregatable address assignments A lot of entries in routing tables : currently reaching Heavy burden for routers => instability… LAN ISP1 ISP2 Same addresses used for ISP1 and ISP2 2 entries for similar addresses

6W02/ How will IPv6 change the world? Global addressing Interface ID 64 bits SLA NLATLA bits 32 bits 13 bits TLA: Top Level Aggregator (/16) NLA: Next Level Aggregator (1/48) SLA: Site Level Aggregator (/64) Private Topology Pubic Topology Node IdentifierNetwork address

6W02/ Allowing Peer-to-peer application deployment VoIP, videoconferencing, content sharing, games… Plug and Play IP services have to become commodity services IP connectivity everywhere at anytime Efficient mobility IP on all wireless technologies Secured transfers How will IPv6 change the world?

6W02/ With IPv6, just use IPv6 addresses P1P2 LAN LAN Internet Accessrouter LAN Accessrouter P1P2 P3 LAN Accessrouter LAN Accessrouter Internet

6W02/ Restoration of the Internet model with IPv6 IPv6 Simple, stable network service => higher performance, more robust, more secure, more manageable Enabling anyone to offer new applications and services => allowing rapid innovation and growth IPv6, a chance for the Internet

6W02/ IPv6 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 device Global and local ones Link-Local Site-LocalGlobal

6W02/ European Projects Instrumental to validate enhanced networking capacities Example with the 6WINIT Project

6W02/ The 6WINIT Project Pilots clinical and other IPv6 applications over wireless networks Uses GPRS, WLAN and later UMTS Initial GPRS not IPv6-enabled, WLAN is, UMTS not available yet Concerned with media and data applications Concerned to make all components IPv6- enabled – but treats also transition Includes Japanese, Korean partners and Polish partners

6W02/ Project 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

6W02/ Integration & deployment of IPv4/v6 services

6W02/ New Generation Networks IP Evolution 1 billion + Connected Devices 100m IPv6 IPv4

6W02/ Deployment steps Products are available today SW & HW Numerous legacy applications are running on v6, others are arriving IPv6 is progressively integrated in network architectures With the goal to provide value added services IPv6 will progressively arrive in corporations and houses with the new OS versions and applications

6W02/ How to introduce IPv6 (1) By providing seamless IPv4 and IPv6 broadband services The 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 v6-in-v4 then v4-in-v6 No constraint on the customer

6W02/ IP version transparency Smart integration mechanisms Dual stack Two native access for the customer Tunneling ISP architecture dependant Translation End-to-end application dependant

6W02/ By offering customized services Needs arrive with the applications Customers have different constraints Security, reliability, investments, operational requirements… At the right speed Let’s invest when necessary But start now to deploy a pilot platform to be able to build a clear transition roadmap! How to introduce IPv6 (2)

6W02/ How will IPv6 change the world? Always-on and everywhere connectivity Broadband access on train, in public buildings, at gas stations.. New devices PDA-Phone, MPx player, Game box, camera… New systems & applications VoIP, videoconferencing, video, TV… E-vehicle E-home E-assistance E-production …

6W02/ Conclusion 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!
