Abilene Participation Fees Effective January 1, 2006: • Abilene Primary Participation - $21,000 Effective January 1, 2007: • Abilene Primary Participation - $22,000 First increase since Abilene was launched in 1998
Hurricane Katrina • Hurricane Katrina strikes the Gulf Coast on August 29th, 2005. • Abilene’s unprotected lambda network link from Houston to Atlanta goes down. The IGP (IS-IS) automatically reroutes around the fault. • On September 1st, 2005 the damage to the carrier network was fully assessed and estimated to take days to repair. • During this time, Abilene was operating with the risk of network isolation if there is a loss of the Chicago to Kansas City link. • A redundancy plan was formulated and approved by Internet2 to have Abilene traffic route over the HOPI wave from Chicago to Seattle in the event that Chicago to Kansas link fails. The Abilene NOC engineers implement the redundancy plan. • Service is restored to the Houston to Atlanta link on September 8th, 2005. No Abilene outages occurred during this period.

Hurricane Katrina We would like to thank our partner Qwest for the extraordinary efforts they made to repair the network. Great job! We also appreciate the support we received from the Abilene NOC and NLR. Thanks!
Abilene Redundancy • Responding to requests of our members, Internet2 has pursued redundancy options with our partner Qwest Communications. • Qwest has agreed to provide on a per port basis, redundant connections to the Abilene router, at the node, for a cost of $400 per month regardless of speed as long as the redundant circuit speed is equal to or less than the primary circuit. • This option is available to any active Abilene Connector who delivers their redundant circuit to the Abilene node. SONET and Ethernet framing methods would be supported under this option.
Abilene Redundancy Most Abilene Connectors Today: What We Can Offer:
Redundancy Offering • We can make the following redundant connections available to our members who bring their circuits to an Abilene node: • VLAN connections through an existing exchange point: • 1 GE $50,000.00 • Physical connections to the router: • OC3 $70,000.00 • OC12 $75,000.00 • OC48 $90,000.00 • OC192 $125,000.00 • 1 GE $80,000.00 • 10GE $125,000.00 • A redundant circuit must be equal to or less than the primary circuit in speed and will not carry traffic unless the primary circuit fails. • Each request will be evaluated on a case basis. The above figures are for budgetary purposes and are subject to change.
Redundancy Offering • Member’s requests for redundant circuits carried back to an Abilene node over the Qwest network will have their requests evaluated on a case-by-case basis for available capacity and pricing. • These types of connections currently must be SONET.
IPv6 Peerings • IPv6 Deployment • Significant number of peers and connectors now have native connections: • Roughly 2/3 of the connectors are IPv6 enabled • Roughly 1/2 of the peers are IPv6 enabled • Connected to Palo Alto PAIX peering fabric at 333 Mbps for IPv6 and IPv4-Multicast experimental, non-production peering • 10 new experimental, non-production IPv6 peerings at the PAIX so far in 2005 • Connected to MCI MAE-West at OC-3 for IPv6-only experimental, non-production peering • Qwest and MCI collaborated in providing the connection
IPv6 Addressing • Abilene has /32 that it can distribute to its members • However, a number of connectors and members have or are acquiring their own address space: • 2001:4e0::/32 Wiscnet • 2001:5e8::/32 Pittsburgh Supercomputing Center • 2001:1860::/32 Pacific Northwest Gigapop • 2001:18e8::/32 Indiana University
IPv6 Security • Abilene NOC activities: • Limiting the v6 prefixes connectors send us (as we do for IPv4) • Limited filtering for peer networks • firstname.lastname@example.org is a mailing list for v6 security topics
Internet2 Involvement with the NAv6TF • Internet2 is active in the North American IPv6 Task Force (NAv6TF). • Rick Summerhill is on NAv6TF advisory committee • Abilene is key network component of the NAv6TF's Moonv6 national test network
Internet2 IPv6 Member Activities • North Carolina State University and Centaur Labs -- IPv6 streaming audio feeds from radio stations WCPE and WZYC • IPv6 H.323 at Georgia Tech • Abilene IPv6-enabled hosts • http://ipv6.internet2.edu/ipv6hosts.shtml
Internet2 Member Multicast Activities • DVGuide - http://db.arts.usf.edu/dvguide/listings.asp • Several campus radio stations multicasting across Abilene • ConferenceXP, a Microsoft Research initiative, relies on multicast and has been deployed at several schools • Access Grid continues to grow • More activity requiring "bridging" to multicast in challenged environments, using the rcBridge software from ANU • NYSERnet, Abilene and Internet2 deploying native IPv6 multicast • IPv6 Multicast demo live at Fall Member Meeting
Multicast Security • Basic measures on Abilene: • Not allowing multicast streams with RFC1918 source addresses • Not allowing multicast streams to "site local" group addresses (126.96.36.199/8) which is a similar idea to RFC1918 addresses, but for group addresses. • Blocking group addresses which are used for application which only have local significance. A good example of this is Norton Ghost. • Other measures are under consideration, such as: • Blocking all IANA reserved multicast group addresses • Place a limit on the number of MSDP SAs each Abilene Connector/Peer can originate
Internet2 Hands-on Multicast Workshops Upcoming Workshops: • Hartford, CT – 4-6 October 2005 • Ann Arbor, Michigan - 17-19 October 2005 • Albuquerque, New Mexico - 2-4 February 2006 http://multicast.internet2.edu/workshops/
Other Advanced Services • MPLS VPN testing – NC-ITEC experimenting (with ITEC Ohio) with creating a multipoint Layer 2 VPN using inter-domain MPLS tunnels and Virtual Private LAN Service (VPLS). Working in both a lab environment and between the ITECs using Abilene. • The goal is to examine multipoint alternatives for a possible Abilene private network service offering.
Network Research Philosophy • Internet2 today does not do network research per se, but seeks to facilitate and support research projects led by faculty at member institutions • Make accessible network resources readily available to this community • Participate in research collaborations and provide support for proposals • Integrate research findings into the evolution of Internet2 network initiatives and services
Network Research Resources • Resources available to researchers: • Abilene Observatory • MAN LAN Exchange Point • HOPI testbed • Collaboration with NLR, Regional Optical Networks and other testbeds
Abilene Observatory The Abilene Observatory is a program that supports the collection and dissemination of network data associated with the Abilene Network. Provides researchers: • Operational data associated with a large-scale network • Data associated with the fundamental properties of basic network protocols. Two components of the Observatory: • Data collected by Abilene engineers using equipment located in the router nodes and operated by the Abilene NOC • Data collected by separate research projects using equipment collocated in the Abilene racks
Abilene Observatory There are more than 30 research projects currently using Observatory data. Some of the more recent additions are: • Flow Sampling and Anomaly Detection , Paul Barford, University of Wisconsin • Assess the Presence and Incidence of Alpha Flows in Backbone Links, Vincenzo Liberatore, Case Western Reserve University • Traffic Management and QoS Provisioning in IP Networks, Hassan Peyravi, Kent State University • Spatio-Temporal Network Analysis, Mark Crovella and Eric Kolaczyk, Boston University. • MINDS Project, Vipin Kumar, University of Minnesota • Study of the Temporal-spatial Correlations in Network Traffic, Don Towsley, University of Massechusetts For a more comprehensive list, see: http://abilene.internet2.edu/observatory/research-projects.html
Project Highlight: PlanetLab • PlanetLab Upgrade • PlanetLab nodes currently located at all Abilene router nodes, connected to the IP network • Upgrade will add connection to an MPLS L2VPN configuration forming a layer2 network where the PlanetLab nodes will provide the routing engines • Abilene becomes the layer2 circuit provider for PlanetLab • Normal users on Abilene don't have direct access to this new "backbone network" • The PlanetLab network can peer with the commodity network • Provides an infrastructure for network research that has national scope

Network Security Basic Premise: Abilene Security Policy is determined by the properties of an IP network • Control is at the edge • Hosts determine when and where to send packets and initiate flows • This control often leads to vulnerabilities • Hosts can become compromised • Hosts may be used to compromise other hosts • Can lead to large amounts of traffic sent to other hosts As a backbone network, we view Abilene as a ‘pipe’ and not a controlling entity
