  1. Implementing Advanced Services Today: IPv6 Atlanta Guy Almes <almes@internet2.edu> on behalf of the Internet2 IPv6 WG 30 May 2000

  2. Outline of Talk • IPv6 and its role within Internet2 • The emerging Internet2 IPv6 Infrastructure • Internet2 IPv6 WG Activities

  3. IPv6 and its role within Internet2 • "Next Generation" of the IP protocol • Resulted from extensive process during the mid 1990s • Two explanations for why IPv6 is important

  4. Explanation #1 • Address Space Exhaustion • IETF Road Working Group of 1992 • CIDR as the 'answer' • Then five years of Internet growth • Multihoming and the breakdown of civic virtue • 802.11 • 3G cell phones • Maybe we do care...

  5. Explanation #2 • A conservative/tasteful iteration on the IPv4 design • Mobility • Multicast and Anycast • Public and private addresses • IPsec • End to End Transparency • Global Addresses

  6. What are the alternatives? • Balkanization of the Internet • firewalls and VPNs • NATs • breaks end-to-end transparency • some applications will not work in this environment

  7. The emerging Internet2 IPv6 Infrastructure • Both backbones support • vBNS: IPv6 over ATM • Abilene: IPv6 over IPv4 • Provisionally COU-free • Peers with the 6TAP for international transit

  8. Abilene IPv6 Backbone • Cisco 7200 routers: • Atlanta, hosted by the SoX • Colorado, hosted by the Front Range GigaPoP • Indianapolis, hosted by Indiana University • Pittsburgh, hosted by PSC • Full mesh of IPv6-over-IPv4 tunnels • 24-by-7 support by the Abilene NOC • Grover Browning

  9. How to play on your campus or gigaPoP • Engage the IPv6 WG • Addressing • Tunneling to the appropriate backbone (or gigaPoP) IPv6 router • Support DNS etc • Reach out to the Comp or Elec departments

  10. Addressing UCAID (ABILENE> 3025 Boardwalk, Suite 100 Ann Arbor, MI 48108 US Netname: ABILENE Netnumber: 2001:0468:0000:0000:0000:0000:0000:0000/35 Coordinator: Finkelson, Dale (DF90-ARIN) dmf@UNL.EDU

  11. Supported Routers • Cisco • IOS 12.2T • Unix and Zebra • *bsd and Linux • Others

  12. Hosts • *bsd • Linux • Windows 2000 • others

  13. IPv6 Working Group • Dale Finkelson <dmf@unl.edu>Michael Lambert <lambert@psc.edu> • Engineering/coordination • Education/training • Exploring the motivation

  14. Spreading the Word • First IPv6 Workshop • May 2001, Univ Nebraska • Planning to support about 8-10 per year • Attend/plan

  15. Examining the Motivation • Why should our community care? • IPv6 preserves end-to-end transparency • improved support for mobility • key for IPsec • key for the scalability of the Internet • when sites are not pure 'clients' • peer to peer • conferencing among three or more sites • SIP IP telephony • The answers must be pragmatic.
