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 12
IPv6 Participants and Connectors IPv6 Participants and Connectors • Participants: 56 • Connectors: 26 • Peers: 34 • 1 Corporate • 3 Federal • 26 International 13

Additional IPv6 Deployment Additional IPv6 Deployment •Backbone unicast enabled • Routing – BGP and IS-IS •6 to 4 tunnel relays: • Indiana University • Pittsburgh Supercomputer Center 15
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 Source: Joe Breen, University of Utah 16
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 17
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 18
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 19

Abilene IPv4/IPv6 Abilene IPv4/IPv6 Measurement 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 21
IPv4/IPv6 Comparative IPv4/IPv6 Comparative Performance Graphics Performance Graphics 22
IPv4/IPv6 Comparative IPv4/IPv6 Comparative Performance Review 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? 23
Internet2 Member IPv6 Internet2 Member IPv6 Activities Activities • North Carolina State University and Centaur Labs -- IPv6 streaming audio feeds from radio stations WCPE and WZYC • IPv6 H.323 at Georgia Tech • NYSERnet experimenting with IPv6 Multicast via the international M6bone effort • IPv6 Multicast Demo at Fall Member Meeting in planning stages • Abilene IPv6-enabled hosts • http://ipv6.internet2.edu/ipv6hosts.shtml 24
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 25
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 26
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 27
Support for IPv6 Support for IPv6 •Tutorials • Two day workshops, hands-on experience • Descriptions and planning guides • http://ipv6.internet2.edu/workshops/index.shtml • http://ipv6.internet2.edu/workshops/setup/ • Alternate discussion/lecture with hands-on lab exercises • Slides are available • http://ipv6.internet2.edu/presentations/ 28
Internet2 Commitment Internet2 Commitment • Internet2 is committed to deploying an IPv6 native dual stack network for the research community. • Internet2 is committed to encouraging connectors, peers, and members to fully deploy IPv6 on their networks. • Internet2 will monitor IPv6 penetration in the future to provide guidance to the community. • Network penetration. • Availability of software and tools • Security Issues 29
