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

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 technologyAccess PoPs very close to university
