Abilene Overview
• 10-Gbps ‘best effort’, over-provisioned IP
network
• Current normal load ~2 Gbps; ~10 Gbps peak
• Carrier provisioned backbone λ’s (Q-Wave)
• ~4.7 9’s availability over past 12 months
• SONET backhaul available to connectors
• IPv4/IPv6, native multicast, MPLS LSPs
• Network research facilitation (data + co-lo)
• Abilene Observatory project
• Extensive domestic and int’l R&E peering
• Cost recovery model motivates network
utilization and bandwidth upgrade
5
Abilene Community
• 39 direct connections (OC-3c  10 Gbps)
• 3 10 Gbps (10 GE) connections
• OC-192c SONET also supported
• 7 OC-48c connections & 3 GE connectors
• 25 connected at OC-12c (622 Mbps) or higher
• 234 Primary Participants – research universities
and labs
• Library of Congress and U.S. Holocaust Museum most
recent additions
• Expanded Access
• 126 Sponsored Participants - Individual institutions, K-12
schools, museums, libraries, research institutes
• 34 Sponsored Educational Group Participants - statebased education networks

Advanced Services Across
Abilene
Advanced Network Services
• IPv6
• Approx. ⅔ connectors, ½ peers are v6 enabled
• 2005: 11 new non-production v6 peerings at Palo Alto PAIX, also
added France Telecom, soon MCI MAE-West
• MPLS
• NC-ITEC experimenting (with ITEC Ohio) with creating a multipoint
Layer 2 VPN using inter-domain MPLS tunnels & Virtual Private LAN
Service (VPLS).
• BRUW: experimenting with how to bandwidth reservation across
packet and circuit switched networks
• Abilene Observatory
• Provides data from router nodes or equip. collocated in Abilene racks
• 30+ research projects currently using Observatory data (see
http://abilene.internet2.edu/observatory/research-projects.html)
• Manhattan Landing (MAN LAN) @ 32 A of A in NYC - partnership
with NYSERNet, Indiana University, and the IEEAF
• A high performance, open bilateral exchange facility for research

Abilene Network Futures
What’s Changed?
• Over the last 5 years, the U.S. research university
community has become wholesale customers of
telecoms for raw assets & ancillary services
• Upwards of 30,000 route-miles of inter-city dark fiber are
held by the U.S. R&E community
• > 60% in the regionals
• More than 20 Regional Optical Networks (RONs) have
emerged
• mostly state based – some with strong gubernatorial support
• often concurrent economic development objectives
• Meanwhile carriers generally did not invest in new optical
infrastructure during the downturn
• Increased end-to-end network transparency
• View of the network as a schedulable resource
17
Next Generation Abilene
• Active examination of new network service models is
underway
• Group A Report - moving beyond the common bearer service
view of best-effort IP
• ‘Core’ and ‘Flexible’ waves
• Hybrid architecture evaluation (HOPI Project)
• IP core using 10→40Gbps λ transport
• Dedicated capabilities using NLR wave and Abilene
• λ’s, GigE channels, MPLS tunnels
• Evaluation of optical transport capabilities
• Both commercial and higher ed owned options (NLR & the
RONs)
• Design & planning collaboration with U.S. &
international partners
• ESnet, TeraGrid, NLR, SURFnet, GEANT2

Next Generation Abilene
Timeline
• October 2007 – End of recent 1-year extension to
Abilene transport MoU with Qwest
• Dictates 3rd-generation network timeline
•
•
•
•
•
Architecture: end 4Q05
Transport provider(s): end 1Q06
Equipment selection: end 2Q06
Backbone deployed: end 4Q06
Connector transition: begin early 2007
• Concurrently, need to review business and management
models
• Coincidentally…
• Late 2007 – expiration of ESnet transport agreement with
Qwest
19
NLR & Abilene
• Group B Report recommended a merger of
Internet2 and NLR as the best way to deliver
to the community the services outlined in the
‘Group A’ report
• Both Boards passed resolutions to begin
consolidation discussions
• Committee of 8 individuals has been appointed to
develop a merger strategy plan
• Work to begin immediately
• Goal is to have a plan ready for each board’s
consideration by the end of Oct.

Next Generation Abilene Design
Considerations
Critical factors:
• Complexity of delivering dynamic network bandwidth
• NLR, RON and international integration
• How do we deliver these services from the campus of one
researcher to the campus of another
• Advanced service support
• Multicast, v6, High Performance Throughput, Measurement
• Enhanced network research facilitation
• Network and end-user security
• Options for increased reliability and additional
services (i.e. Commodity Internet services)
