Why IPv6 ?

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

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!

P2P protocols are not so simple! LAN Internet LAN NAT NAT 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 complicated to be deployed Home LAN Internet Home LAN NAT NAT P3 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 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

IPv4 routing Addresses scarcity and multi-homing lead to un-aggregatable address assignments A lot of entries in routing tables: currently reaching 120.000 Heavy burden for routers => instability… Same addresses used for ISP1 and ISP2 ISP1 2 entries for similar addresses LAN ISP2

How will IPv6 change the world? Global addressing Interface ID 001 TLA NLA SLA 13 bits 32 bits 16 bits 64 bits Network address Node Identifier Public Topology Private Topology TLA: Top Level Aggregator (/16) NLA: Next Level Aggregator (1/48) SLA: Site Level Aggregator (/64)

How will IPv6 change the world? 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

With IPv6, just use IPv6 addresses LAN Internet LAN Access router Access router P1 P2 LAN Internet LAN Access router Access router P3

The IPv4 Patchwork Architecture NAT NAT NAT NAT NAT NAT boxes manipulate the packets !!!! Complex routing tables No end-to-end SLA What about always-on & mobility ?

The Solid IPv6 Architecture 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 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 Global Site-Local Link-Local

IPv6: The Solution IPv4 IPv6 Everywhere 32 bit address length. 200 Million addresses, 75% in the US. Routing table size. 128 bit address length. Unlimited number of addresses Routing table scalability. Peer to peer Difficult to implement. NAT, proxies. Native end to end support. End to end QoS & Security. Mobility Limited support. Built-in (auto configuration). + Mobile IP Configuration Management More and more difficult (NAT, proxys, DHCP server) Serverless autoconf. 0configuration support. Anycast. Router configuration.

IPv6 in the World Europe: lots of trials, operational services are starting 2 1 Japan, Korea, Taiwan, Singapore, China 3 US start to consider IPv6

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

The 6WINIT Project Pilots clinical and other IPv6 applications over wireless networks Use 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 and Polish partners

Project Support & Infrastructure Project around 3.5 Euro of EC money – 7 MEuro over 2 years Uses IPv6-based networks 6NET/GEANT is the selected network Has 16 partners in 10 countries Tries to bridge gap between 3GPP and IETF Sets up real systems demonstrators Using GEANT as connecting network so far

Access technology independent multiaccess 6WINIT Plate-form “UKT-Hospital” Düsseldorf CN1 SGSN Ericsson Router (HA) GGSN GPRS / UMTS Internet 6bone edge router CN2 CN3 WLAN 6bone Access technology independent multiaccess MN in the Ambulance “CHIME” London 6bone edge router Access router EHR Server (Electronic Health Care) CN Tübingen LAN “docking station” 6WINDGate (HA) IPv6 “UCL” IPv4 MN IPv6 in IPv4 tunnel Access router “Whittington Hospital”

Integration & Deployment of IPv4/v6 Services

New Generation Networks 1 billion + Connected Devices IPv4 IPv6 IP Evolution 100m Early Adopter 1999 2000 2001 2002 2003 2004 Target Segments Mass Market

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

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

IP Version Transparency Smart integration mechanisms Dual stack Two native access for the customer Tunneling ISP architecture dependant Translation End-to-end application dependant

How to introduce IPv6 (2) By offering customized services Needs arrive with 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!

IPsec more & more essential Wireless Environment How merging wireless and security: By using IPsec Access Point v4 Access Point Access Point v6 Access Point v4 v6

We also need smart filters… Management of security rules IPsec traversal Intrusion detection Dynamic filters Crown F F Jewels External Networks Internal Network Mission Critical Systems

… and Secured Software Architecture on top of the Networks The network is not responsible for software bugs Software must be more robust OS must include security monitoring and control functions Trusted Platforms (ongoing Industrial alliances)

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 …

Conclusion Start now and take a leading position! 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 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 fixed and wireless access networks Start now and take a leading position!
