    • 10. Abilene Observatory
      • A program to provide enhanced support of computer science research over Abilene
        • Create network data archive
          • Consists of many separate databases on a variety of servers
          • Forms a large correlated database
          • Create tools to access the database
          • Support from/for network researchers
        • Provide data views for a real-time snapshot of Abilene
        • Provide server collocation for direct network measurement and experimentation
          • Resources reserved for additional servers
            • Power (DC), rack space (2RU), router uplink ports (GigE)
          • Initial deployment is PlanetLab overlay network
          • Additional requests from SDSC AMP project and research team from Japan
    • 11. Advanced Engineering
      • MPLS Experiments – Teragrid examples
      • Large MTUs
      • Security and the REN-ISAC
      • Advanced Restoration Techniques
      • FAST TCP Experimentation
    • 12. Advanced Engineering - Example
      • FAST TCP is an advanced, delay-based TCP flavor being developed at Caltech
        • Internet2 is working with Caltech, SoX, PNW, NC-ITEC, and PSC to test FAST TCP over a production network - Abilene
        • Results include:   - Congesting 2.5Gb/s OC-48 link going into SoX with FAST TCP traffic with no adverse effects on conventional traffic
          • no packet loss during 1-hour test with a delay increase of only 5 ms
        • Evidence that FAST TCP plays nicely with production traffic
        • Concurrently, a useful network performance test tool was developed - i2perf  
    • 13. Next Generation Optical Networking
    • 14. One underlying hypothesis: the rise of the RONs
      • The fundamental nature of regional networking is changing
      • The GigaPoP model based on provisioned, high-capacity services steadily is being replaced – on the metro and regional scales
      • A model of facility-based networking built with owned assets – Regional Optical Networks (RONs) – has emerged
      • Notably, the importance of regional networks in the traditional three-level hierarchy of U.S. advanced networking for R&E is not diminished
    • 15. RONs will influence Infrastructure Efforts
      • Abilene Network
      • FiberCo
      • Internet2’s role in NLR
      • HOPI
      • Quilt (Fiber project)
    • 16. FiberCo
      • Designed to support optical initiatives
        • Regional
        • National
      • Not an operational entity – Will not light any fiber
      • Fiber options
        • Holding company for any future initiatives
        • Assignment vehicle
          • Regional initiatives
          • National initiatives (e.g., NLR)
      • FiberCo progress: assignments underway and anticipated
        • NLR
        • Wyoming, Indiana, and Michigan
        • Pursuing Texas, upstate New York, and Florida
      • Expect to cover Internet2 investment ($2.7M) in 2004
    • 17. Hybrid Optical/Packet Infrastructure (HOPI)
      • Need to converge the two worlds of packet (Abilene) and optical circuit (GLIF) networking
        • Concern about IP packet network scaling (lack of >10 Gbps transport) and drawbacks (security, large data flows)
        • Widely recognized that the current GLIF optical networking model does not scale beyond a limited number of sites
        • However, dedicated capabilities allow a vehicle for advanced testing (transport technologies beyond TCP) and very high-end requirements
        • Potential end-states:
          • Hybrid model – with centrally and perhaps ‘user’ driven allocation of dedicated capabilities
          • Impact of hybrid experience on packet network design
    • 18. HOPI – Chris Heermann
      • Abilene high-performance IP network
        • Capabilities for MPLS tunnels
      • 10-Gbps  over full NLR footprint
        • Expect some type of ‘TDM’ infrastructure to be provisioned by Internet2 in collaboration with NLR
          • Additional capital investment required
      • Tie points for international collaboration
        • MAN LAN (NYC) and IEEAF  (NYC-Amsterdam)
        • StarLight collaboration (Chicago)
        • Expect similar capabilities to emerge in Seattle (Pacific Wave)
    • 19. Internet2 MAN LAN 15454
    • 20. Infrastructure Priorities for 2004
      • Drive process to develop HOPI architecture and begin testbed efforts
      • Accelerate RON paradigm/deployment
        • Quilt Fiber project
        • FiberCo
      • Expand Abilene Observatory to support a broader set of network researchers
      • Expand Abilene services (security & performance) and encourage connector upgrades
      • Play a critical role in NLR development
        • Governance and implementation
