Abilene – May, 2002
IP-over-SONET backbone (OC-48c, 2.5 Gbps)
53 direct connections
•
•
•
•
4 OC-48c connections
1 Gigabit Ethernet trial
23 will connect via at least OC-12c (622 Mbps) by 1Q02
Number of ATM connections decreasing
215 participants – research universities & labs
• All 50 states, District of Columbia, & Puerto Rico
• 15 regional GigaPoPs support ~70% of participants
Expanded access
• 50 sponsored participants
– New: Smithsonian Institution, Arecibo Radio Telescope
• 23 state education networks (SEGPs)

Abilene international connectivity
Transoceanic R&E bandwidths growing!
• GÉANT – 5 Gbps between Europe and New York City now
Key international exchange points facilitated
by Internet2 membership and the U.S.
scientific community
•
•
•
•
•
•
STARTAP & STAR LIGHT – Chicago (GigE)
AMPATH – Miami (OC-3c  OC-12c)
Pacific Wave – Seattle (GigE)
MAN LAN - New York City (GigE/10GigE EP soon)
CA*NET3/4: Seattle, Chicago, and New York
CUDI: CENIC and Univ. of Texas at El Paso
International transit service
• Collaboration with CA*NET3 and STARTAP

Future of Abilene
Original UCAID/Qwest agreement
amended on October 1, 2001
Extension for another 5 years – until
October, 2006
• MoU originally expired March, 2003
Upgrade of Abilene backbone to optical
transport capability - ’s (unprotected)
• x4 increase in the core backbone bandwidth
–OC-48c SONET (2.5 Gbps) to 10-Gbps DWDM

Key aspects of next generation
Abilene backbone - I
Native IPv6
• Motivations
– Resolving IPv4 address exhaustion issues
– Preservation of the original End-to-End Architecture model
• p2p collaboration tools, reverse trend to CO-centrism
– International collaboration
– Router and host OS capabilities
• Run natively - concurrent with IPv4
• Replicate multicast deployment strategy
• Close collaboration with Internet2 IPv6 Working Group on
regional and campus v6 rollout
– Addressing architecture

Key aspects of next generation
Abilene backbone - II
Addition of new measurement capabilities
• Enhance active probing (Surveyor)
– Latency & jitter, loss, TCP throughput
• Add passive measurement
• Support for computer science research – “Abilene
Observatories” – archive/measurement/experiment
• Support of Internet2 End-to-End Performance Initiative
– Intermediate performance beacons
Network resiliency
• Abilene ’s will not be protected like SONET
• Increasing use of videoconferencing/VoIP impose tighter
restoration requirements (<100 ms)
• Options:
– MPLS/TE fast reroute (initially)
– IP-based IGP fast convergence (preferable)

Next generation router selection
Extensive router specification and test plan
developed
• Team effort: UCAID staff, NOC, NC and Ohio ITECs
• Discussions with four router vendors
Tests focused on next gen advanced services
•
•
•
•
High performance TCP/IP throughput
High performance multicast
IPv6 functionality & throughput
Classification for QoS and measurement
3 router platforms tested & commercial ISPs
referenced
 New Juniper T640 platform selected

Abilene international connectivity
model
Abilene is a GTRN partner
• Already peering with GTRN router in New York City
Peering at major int’l EPs in U.S. encouraged
•
•
•
•
Chicago: Star Light (migration from STAR TAP)
Seattle: Pacific Wave
Miami: AMPATH
New York City: Manhattan Landing (MAN LAN) - coming
soon
• Los Angeles?
Direct BGP peering preferred
• via Layer-2 EP media or direct connection
ATM support generally ends by Sept 2003
• No new ATM peers

Conclusions – Abilene future
Backbone upgrade project underway
•
•
•
•
Partnership with Qwest extended thru 2006
Juniper T640 routers selected for backbone
10-Gbps backbone  deployment starts this fall
Incremental, non-disruptive transition
Advanced service foci
• Native, high-performance IPv6
• Enhanced, differentiated measurement
• Network resiliency
Please inform us now of any changes to
international peering connections
anticipated to occur this year
