  • This is a general overview presentation about Internet2. Internet2 is a consortium, led by US universities, which is recreating the partnership among academia, industry and government that fostered today’s Internet in its infancy.

      • 92 sponsored participants, expected to increase
      • 32 State networks, expected to increase
  • 8. SC2003 Bandwidth Challenge
  • 9. MAN LAN Exchange Point
    • Internet2/NYSERnet/Indiana U partnership
    • Ethernet Switch
      • Cisco 6513 (with new fabric/backplane soon)
      • Located in 32 Avenue of the Americas
        • same building as Abilene New York City router node
      • CA*net (Canada) bringing in OC-192 to same building
    • Transatlantic (Abilene/SURFnet) connection
      • OC-192c from Amsterdam
      • Enabled by IEEAF and Tyco
    • GLIF (Global Lambda Integration Facility)
      • Installing Cisco 15454 switch – more on this later
  • 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
