Abilene ParticipantsDecember 2003
IP-over-DWDM (OC-192c) and IP-over-SONET OC-48c Backbone47 Connectors (OC-3c 10 GigE), may drop to 39 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
• 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

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

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
Next Generation Optical Networking
04/08/23 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

RONs will influence Infrastructure Efforts

Internet2’s role in NLR
HOPI
Quilt (Fiber project)

FiberCo
Designed to support optical initiatives• Regional• National
Not an operational entity – Will not light any fiberFiber 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

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

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
