  • Note these are Abilene-specific, second two not members. We peer with XXX
  • Why between now and the end of the year? Partly driven by existing Abilene lifetime BUT, This is NOT about just an incremental improvement of the Abilene backbone network; or even a massive improvement of the Abilene network - look at whole new architecture - look at whole new cost model - take into account the major state, regional network buildout, NLR, etc.

  • Abilene Overview
    • 10-Gbps ‘best effort’, over-provisioned IP network
      • Current normal load ~2 Gbps; ~10 Gbps peak
    • Carrier provisioned backbone λ’s (Q-Wave)
      • ~4.7 9’s availability over past 12 months
    • SONET backhaul available to connectors
    • IPv4/IPv6, native multicast, MPLS LSPs
    • Network research facilitation (data + co-lo)
      • Abilene Observatory project
    • Extensive domestic and int’l R&E peering
    • Cost recovery model motivates network utilization and bandwidth upgrade
  • Abilene Community
    • 39 direct connections (OC-3c  10 Gbps)
      • 3 10 Gbps (10 GE) connections
        • OC-192c SONET also supported
      • 7 OC-48c connections & 3 GE connectors
      • 25 connected at OC-12c (622 Mbps) or higher
    • 234 Primary Participants – research universities and labs
      • Library of Congress and U.S. Holocaust Museum most recent additions
    • Expanded Access
      • 126 Sponsored Participants - Individual institutions, K-12 schools, museums, libraries, research institutes
      • 34 Sponsored Educational Group Participants - state-based education networks
    • See: http://abilene.internet2.edu/

  • The Abilene Network
  • Abilene Federal & Research Peerings
  • Abilene International Network Peerings
  • Advanced Services Across Abilene
  • Advanced Network Services
    • IPv6
      • Approx. ⅔ connectors, ½ peers are v6 enabled
      • 2005: 11 new non-production v6 peerings at Palo Alto PAIX, also added France Telecom, soon MCI MAE-West
    • MPLS
      • NC-ITEC experimenting (with ITEC Ohio) with creating a multipoint Layer 2 VPN using inter-domain MPLS tunnels & Virtual Private LAN Service (VPLS).
      • BRUW: experimenting with how to bandwidth reservation across packet and circuit switched networks
    • Abilene Observatory
      • Provides data from router nodes or equip. collocated in Abilene racks
      • 30+ research projects currently using Observatory data (see http://abilene.internet2.edu/observatory/research-projects.html )
    • Manhattan Landing (MAN LAN) @ 32 A of A in NYC - partnership with NYSERNet, Indiana University, and the IEEAF
      • A high performance, open bilateral exchange facility for research
  • Abilene Network Futures
  • What’s Changed?
    • Over the last 5 years, the U.S. research university community has become wholesale customers of telecoms for raw assets & ancillary services
      • Upwards of 30,000 route-miles of inter-city dark fiber are held by the U.S. R&E community
        • > 60% in the regionals
      • More than 20 Regional Optical Networks (RONs) have emerged
        • mostly state based – some with strong gubernatorial support
        • often concurrent economic development objectives
      • Meanwhile carriers generally did not invest in new optical infrastructure during the downturn
    • Increased end-to-end network transparency
    • View of the network as a schedulable resource
  • Next Generation Abilene
    • Active examination of new network service models is underway
      • Group A Report - moving beyond the common bearer service view of best-effort IP
        • ‘ Core’ and ‘Flexible’ waves
    • Hybrid architecture evaluation (HOPI Project)
      • IP core using 10->40Gbps λ transport
      • Dedicated capabilities using NLR wave and Abilene
        • λ’s, GigE channels, MPLS tunnels
    • Evaluation of optical transport capabilities
      • Both commercial and higher ed owned options (NLR & the RONs)
    • Design & planning collaboration with U.S. & international partners
      • ESnet, TeraGrid, NLR, SURFnet, GEANT2
  • Next Generation Abilene Timeline
    • October 2007 – End of recent 1-year extension to Abilene transport MoU with Qwest
      • Dictates 3rd-generation network timeline
        • Architecture: end 4Q05
        • Transport provider(s): end 1Q06
        • Equipment selection: end 2Q06
        • Backbone deployed: end 4Q06
        • Connector transition: begin early 2007
      • Concurrently, need to review business and management models
    • Coincidentally…
      • Late 2007 – expiration of ESnet transport agreement with Qwest
  • NLR & Abilene
    • Group B Report recommended a merger of Internet2 and NLR as the best way to deliver to the community the services outlined in the ‘Group A’ report
    • Both Boards passed resolutions to begin consolidation discussions
      • Committee of 8 individuals has been appointed to develop a merger strategy plan
        • Work to begin immediately
      • Goal is to have a plan ready for each board’s consideration by the end of Oct.
  • Abilene / NLR Map
  • Next Generation Abilene Design Considerations
    • Critical factors:
    • Complexity of delivering dynamic network bandwidth
    • NLR, RON and international integration
      • How do we deliver these services from the campus of one researcher to the campus of another
    • Advanced service support
      • Multicast, v6, High Performance Throughput, Measurement
    • Enhanced network research facilitation
    • Network and end-user security
    • Options for increased reliability and additional services (i.e. Commodity Internet services)
