5 Presentation_ID 555 With millions of new devices becoming IP aware, the need for increased addressing and plug & play networking is only met with the implementation of IPv6 IP – The Application’s Convergence Layer EthernetOpticalE-PowerWirelessStorageChannelCATV P S DN xDSL IP version 6 More to Come

6 Presentation_ID 666 A need for IPv6? IETF IPv6 WG began in early 90s, to solve addressing growth issues, but CIDR, NAT,… were developed IPv4 32 bit address = 4 billion hosts ~37% of the IPv4 address space is still unallocated (08/02) General perception is that “IPv6 has not yet taken hold strongly” IPv4 Address shortage is not [yet] true for all regions Private sector requires a business case Data on Wireless infrastructure emerges recently Internet growth!!!But reality looks far better for the coming years!!! To sustain the Internet growth!!!

7 Presentation_ID 777 IP Address Allocation History 1981 - IPv4 protocol published 1985 ~ 1/16 of total space 1990 ~ 1/8 of total space 1995 ~ 1/3 of total space 2000 ~ 1/2 of total space 2002.5 ~ 2/3 of total space This despite increasingly intense conservation efforts PPP / DHCP address sharing NAT (network address translation) CIDR (classless inter-domain routing) plus some address reclamation Theoretical limit of 32-bit space: ~4 billion devices Practical limit of 32-bit space: ~250 million devices (RFC 3194)

8 Presentation_ID 888 Do We Really Need a Larger Address Space? Internet Population ~945M by end CY 2004 (source Computer Industry Almanac) – only 10-15% How to address the future Worldwide population? (~9B in CY 2050) Emerging Internet countries need address space, eg: China uses nearly 2 class A (11/2002), ~20 class A needed if every student (320M) has to get an IP address Mobile Internet introduces new generation of Internet devices PDA (~20M in 2004), Mobile Phones (~1.5B in 2003), Tablet PC Enable through several technologies, eg: 3G, 802.11,… Transportation – Mobile Networks 1B automobiles forecast for 2008 – Begin now on vertical markets Internet access on planes, eg. Lufthansa – train, eg. Narita express Consumer, Home and Industrial Appliances During the life cycle of a technology, a new product is often considered to have reached the early majority – or the mass market – after achieving 22 percent penetration.

26 Presentation_ID 26 IETF v6Ops Working Group Follow-up of IETF NGTrans WG The IPv6 Operations (v6ops) working group of the IETF is under the Operations and Management Area, and has as its overall goal assisting the transition to IPv6, the next generation Internet protocol chosen by the IETF community. Http:// charter.html

27 Presentation_ID 27 IPv4-IPv6 Transition / Co-Existence A wide range of techniques have been identified and implemented, basically falling into three categories: (1)Dual-stack techniques, to allow IPv4 and IPv6 to co-exist in the same devices and networks (2)Tunneling techniques, to avoid order dependencies when upgrading hosts, routers, or regions (3)Translation techniques, to allow IPv6-only devices to communicate with IPv4-only devices Expect all of these to be used, in combination

28 Presentation_ID 28 Dual Stack Approach Dual stack node means: Both IPv4 and IPv6 stacks enabled Applications can talk to both Choice of the IP version is based on name lookup and application preference TCPUDP IPv4IPv6 Application Data Link (Ethernet) 0x08000x86dd TCPUDP IPv4IPv6 IPv6-enable Application Data Link (Ethernet) 0x08000x86dd Frame Protocol ID Preferred method on Application’s servers

29 Presentation_ID 29 Dual Stack Approach & DNS In a dual stack case, an application that: Is IPv4 and IPv6-enabled Asks the DNS for all types of addresses Chooses one address and, for example, connects to the IPv6 address DNS Server IPv4 IPv6 = * ? 3ffe:b00::1

93 Presentation_ID 93 IPv6 on Broadband Infrastructure Requirements CPE PE ISP Host ISP provisioning system How do we get the configuration information and prefixes from the ISP provisioning system, to the PE, from the PE to the user CPE, and from the CPE to the end user hosts? Routes for delegated prefixes/addresses also need to be injected into the ISP’s routing system. ??? Prefix Delegation Assignment of variable length prefixes Independent of end user topology Media independent Additional Informations (DNS, NTP,, SMTP, POP, etc)

94 Presentation_ID 94 Large Scale Deployment Suggested solution CPE PE ISP Host ISP provisioning system The PE can also send RA’s on the PE-CPE link, and the CPE can auto- configure an “uplink” address. Prefix should be different from the prefix assigned to the user. DHCPND/DHCPAAA (1) CPE sends DHCP solicit, with ORO = PD (2) PE sends RADIUS request for the user (3) RADIUS responds with user’s prefix(es) (4) PE sends DHCP REPLY, with Prefix Delegation options (5) CPE configures addresses from the prefix on its downstream interfaces, and sends an RA. O-bit is set to on. (6) Host configures addresses based on the prefixes received in the RA. As the O-bit is on, it send a DHCP INFORMATION-REQUEST message, with an ORO = DNS (7) CPE sends a DHCP REPLY containing request options. Note that the CPE is configured as a DHCP client upstream, and as a DHCP server downstream. The DHCP downstream server acts as a cache, and uses the options received on the upstream interface.

110 Presentation_ID 110 What it is A 3 year research project funded by the European Commission to prepare the Next Generation Internet.

111 Presentation_ID 111 Main goals To build and operate a dedicated international IPv6 network, and use this network to validate that the demands for the continuous growth of the global Internet can be met with the new IPv6 technology. To help European research and industry to play a leading role in defining the next generation of networking and application technologies that go beyond the current state of the art.

112 Presentation_ID 112 Operate an international pilot service such that geographically dispersed groups can interwork using native IPv6 facilities Validate the migration strategies for integrating IPv6 with the existing IPv4 infrastructure (core and access networks) Study and implement coexistence and migration techniques, and transition tools Introduce and intensively test state of the art IPv6 services Sub-objectives

113 Presentation_ID 113 Sub-objectives cont. Test state of the art IPv6 applications and access to legacy IPv4 applications and content Evaluate the deployment and manageability of a large IPv6 network including physical infrastructure, address allocation, registries, routing and DNS operation Exploit the synergy between European NRNs and major industrial partners Collaborate with other IPv6 projects; offering the testbed for the support of their activities
