  over the next year
• 2 10 GigE connections, expected to increase next
  year
• 6 OC-48c, probably will remain the same
• 2 GigE connection, expected to increase next
  year
• 14 OC-12c, probably will remain the same next
  year
• 23 OC-3c, expected to decrease next year
• 224 participants research universities labs
• All 50 states, District of Columbia, Puerto
  Rico
• Aggregation on the rise!
• Expanded access
• 92 sponsored participants, expected to increase
• 32 State networks, expected to increase

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
• CAnet (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

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 RE is not diminished

15
RONs will influence Infrastructure Efforts

• Abilene Network
• FiberCo
• Internet2s 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
  gt10 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)

Infrastructure Prioritiesfor 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
