Abilene IPv6 History Abilene IPv6 History

  • Substantial input from the Internet2

IPv6 working group

  • Tunnel network deployed 2001
  • Migration to native, dual stack

implementation at end of 2001 (Cisco 12008)

  • Native dual stack was default for the

upgrade (OC 192 + Juniper T640)

  • Early testing

  • Routing – BGP and IS-IS
  • 6 to 4 tunnel relays:
  • Indiana University
  • Pittsburgh Supercomputer Center

Deployment Issues Deployment Issues

While Abilene and Gigapops are IPv6- enabled, a “last mile” problem persists as it relates to IPv6. Theories:

  • Hardware doesn’t support IPv6
  • Application server time-outs
  • Difficulty convincing administrators of value
  • Ensuring security isn’t being compromised
  • Application protocols don’t support IPv6

IPv6 Security IPv6 Security

  • Abilene NOC activities:
  • Limiting the v6 prefixes connectors send us as

we do for IPv4

  • Limited filtering for peer networks
  • New v6-security e-mail list

Deployment Issues Deployment Issues

  • [This is an old slide, but unfortunately,

its still true]

  • Many monitoring tools are missing,

impacting security

  • Schools are reluctant to deploy fully

because of potential for attacks

  • For example, difficulty in supporting access

lists that monitor address/port number – extended header implementation problem

IPv6 Multicast IPv6 Multicast

  • Abilene is IPv6 Multicast enabled, but is

not currently part of the global m6bone infrastructure

  • NYSERnet, New York’s research and

education network, is configuring IPv6 Multicast across their backbone

Abilene IPv4/IPv6 Measurement Abilene IPv4/IPv6 Measurement

  • Backbone measurements via IPv4 and IPv6:
  • BWCTL – Bandwidth Control
  • OWAMP – One Way Active Measurement

Protocol

  • Measurements to and from Abilene backbone
  • http://e2epi.internet2.edu/pipes/ami/pmp-info.html
  • Difference between IPv6 and IPv4

performance on Abilene is indistinguishable

IPv4/IPv6 Comparative Performance Review IPv4/IPv6 Comparative Performance Review

  • Reviewed Abilene backbone 180 TCP

throughput (iperf) measurements for a specific period – May 12 around 13:00 UTC.

  • Measurement systems have 1GigE interfaces
  • Measurements averaged 980Mbps with IPv4

tests and 977Mbps with IPv6 tests

  • IPv6 lags IPv4 TCP throughput by about .1 -

.3 percent for most measurements across same links.

  • Other than saying that IPv6 performance

differences are insignificant, do these measurements say anything else?

Applications Applications

  • Currently monitoring applications like
  • VRVS (CalREN)– IPv6 support in

development

  • Internet2 detective – detecting IPv6
  • DVTS (Wide)
  • Preliminary interest in finding synergies

with amateur radio community and IPv6

IPv6 Routing IPv6 Routing

  • Revising policies for IPv6 routing with

international peers and commercial networks (via experimental, non-production peerings)

  • Some of revised policies may apply to IPv4

unicast and multicast

  • Feedback from Abilene connectors and

international peer networks is being solicited

  • IPv6 Transit options from commercial IPv6

network provider under investigation

slide-27
SLIDE 27

IPv6 Routing (continued) IPv6 Routing (continued)

  • Question: Should Abilene Network advertise

routes received from Asian-Pacific peer networks to other Asian-Pacific Networks?

  • Policies being considered:
  • If peer network wishes to send Abilene both non-

commercial and commercial routes, commercial routes should/must be tagged with a commercial community string

  • Routing policy should be symmetric between

Abilene and peer network
