1. 1 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 "That's one small step for man, one giant leap for mankind" Neil Armstrong July 20, 1969 European Telcos investigate IPv6 deployment mechanisms…. Magnus Krampell, EURESCOM

2. 2 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Armstrong project partners

3. 3 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Rationale for the Armstrong project Operational experience needs to be gained by the Internet community with the deployment of the IPv6 protocol suite Appropriate transition mechanisms and strategies for various scenarios are needed This project can be seen as an IPv6 deployment trial with a European provider testbed.

4. 4 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Transition strategies IPv4 to IPv6 Which are the possible transition strategies for an incremental transition from IPv4 to IPv6? Which advantages and disadvantages do these transition mechanisms for ISPs offer (costs, investment protection, uninterrupted operations,...) What should “Legacy” (IPv4) ISPs do (what could “Greenfield” ISPs do)?

5. 5 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Different tasks to be performed... 1(Native) IPv6 use over legacy IPv4 networks:  6 over 4  6 to 4  Tunnel Broker 2IPv6 hosts communicating with IPv4 hosts (and vice-versa):  Socks  NAT-PT  BIS (Bump-In-the-Stack) 3Legacy IPv4 applications working over IPv6 networks  DSTM

6. 6 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Do nothing / Let users use external Tunnel Broker

7. 7 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Offer Tunnel Broker and Tunnel Server

13. 13 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Alternative path: Offer edge only IPv6 network (late/final)

14. 14 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 IPv6 server IPV4 only network IPv6 native network NAT-PT IPv6 host IPv4 server IPv4 host Things one could do as a new IPv6-only ISP

15. 15 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Phases for transition Phase 1 Legacy IPv4 Internet (As we knew it) IPv6 Ocean IPv4 Islands, legacy v4 appl A large IPv4 net, a large IPv6 net Large IPv4 Ocean, Small IPv6 islands IPv4 IPv6 DSTM NAT-PT BIS SOCKS "4to6?"

16. 16 IPv6 - a small step for IP but a giant leap for Telcos IST’2000 Nice, November 8, 2000 Combinations of Mechanisms... IPv4 -> IPv4 (over IPv6 network) IPv6 -> IPv6 (over IPv4 network) IPv4 -> IPv6 (translate + tunnel or vice versa) IPv6 -> IPv4 (translate + tunnel or vice versa) IPv4 IPv6 IPv4 IPv6 Early Late
