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

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 applicationsdevelopment
¡Demonstrate next generationnetworking capabilities
¡Create facilities for networkresearch
Abilene Goals, continued
¡Support Internet2 multicast¡Support Internet2 QoS
architecture as it evolves¡Support other advanced
functionality as it evolves¡Maximize robustness¡Minimize latency

Key Attributes
¡Benefit from Qwest OC-48 Sonetcapacity 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 nativemulticast¡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 togigaPoP• 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
