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

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 7200’s running EFT code. Has been allocated 2001:0468/35

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

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.

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.

What are the motivators for IPv6? Retaining end-to-end transparency. Making public addresses available, thus reducing the reliance on NAT’s. Allows IPsec to work more easily. Manageability of Networks. End-to-End networks are easier to understand and manage.

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.

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.

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 http://ipv6.internet2.edu/workshops/workshop-ufl.shtml

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. If you want to help contact: Dale Finkelson dmf@unl.edu Michael Lambert lambert@psc.edu
