Topics

• History and state of v6 in Abilene
• Motivations
• V6 working group activities

3
Abilene

• Operates as an IPv6 network.
• There are 4 Abilene Core nodes
• Sunnyvale, Indianapolis, Pittsburg and Denver.
• These are interconnected by a full mesh of
  tunnels.
• Cisco 7200s running EFT code.
• Has been allocated 20010468/35

4
Abilene

• What the Wide project taught us.
• What you can expect in the Next Generation
  Abilene.

5
How many Gigapops.

• There are about 10 connected gigapops.
• These are either tunneled into the backbone or
  natively connected via ATM.
• These sites are allocated a /40 out of the
  Abilene address space.
• These run BGP between themselves and the core.

6
How many actual sites

• We estimate 15 to 20 actual connected sites at
  this time.
• These sites are allocated a /48 out of the
  address space.
• Equivalent to a /16 with 64 bits of host space.
• Increasing as we teach more sites about how to
  add v6 capability.

7
What are the motivators for IPv6?

• Retaining end-to-end transparency.
• Making public addresses available, thus reducing
  the reliance on NATs.
• Allows IPsec to work more easily.
• Manageability of Networks.
• End-to-End networks are easier to understand and
  manage.

8
What are the motivators for IPv6?

• Take advantage of new capabilities on V6.
• Addressing architectures
• Renumbering efficiencies
• More integration of Multicast
• New version of ICMP
• Insure interconnectivity with our International
  partners.

9
Status of International connections

• Abilene Peering relationships
• 6Tap at the MREN.
• WIDE at Sunnyvale.
• Over a DS-3 to Japan
• NORDUnet at NYC from the PSC router.
• CUDI of Mexico in Southern California
• We want this to expand. Abilene will transit IPv6
  traffic for now as an incentive to encourage IPv6
  use.

10
What are we actively doing

• Testing at ITEC
• Testing network throughput more then
  interoperability.
• IPv6 networking workshops.
• We have done 5 of these since May
• We have 5 or 6 more scheduled

What is the goal here?

• To play an activist role in the deployment of
  IPv6 networks.
• To insure that our community is a leader in
  deployment of new technology.
