GigaPoPs
 Variety of services and styles
• Technical and organizational
differences
• Mixture of technologies
 Common approaches to:
• IP as common bearer service
• Inter-gigaPoP routing policy and design
• Measurement
• Trouble tickets among network
operations centers

The Abilene Network
Abilene Timeline
 Announced: April 1998
 First demonstration: September 1998
 Operations officially begin: February
1999
 50+ connected institutions:
September 1999
Abilene Goals
 Support Internet2 applications
development
 Demonstrate next generation
networking capabilities
 Create facilities for network
research
Abilene Goals, continued
Support Internet2 multicast
Support Internet2 QoS
architecture as it evolves
Support other advanced
functionality as it evolves
Maximize robustness
Minimize latency
Abilene Project Partners

 Qwest Communications
 Cisco Systems
 Nortel Networks
 Indiana University
Key Attributes
 Benefit from Qwest OC-48 Sonet
capacity and collocation sites
 Benefit from Nortel OC-192 Sonet kit
and Lucent fiber
 Benefit from Cisco GSR 12000 series
routers in support of QoS and native
multicast
 NOC Provided by Indiana University
Architecture
 10 core nodes
• Each located at a Qwest PoP
• Each with a Cisco 12008 router
• Rack also contains measurements/
management computers
 Interior lines connect core nodes
• OC-48 Sonet
• IP-over-Sonet interfaces
 Access lines connect from core node to
gigaPoP
• IP-over-Sonet or IP-over-ATM possible
• OC-3 and OC-12 typical
Abilene Characteristics
 2.4 Gbps (OC48) among gigaPoPs,
increasing to 9.6 Gbps (OC192)
 Connections at 622 Mbps (OC12) or
155 Mbps (OC3)
 IP over Sonet technology
 Access PoPs very close to university
