Implementing Advanced Services Today: IPv6

AtlantaGuy Almes <almes@internet2.edu>on behalf of the Internet2 IPv6 WG

30 May 2000

Outline of Talk

IPv6 and its role within Internet2

The emerging Internet2 IPv6 Infrastructure

Internet2 IPv6 WG Activities

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

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...

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

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

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

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

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

IPv6 Working Group

Dale Finkelson <dmf@unl.edu>Michael Lambert <lambert@psc.edu>

Engineering/coordination Education/training Exploring the motivation

Spreading the Word

First IPv6 Workshop May 2001, Univ Nebraska

Planning to support about 8-10 per year

Attend/plan

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.
