¡ 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 Internet2 GigaPoPs 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
¡UCAID ¡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 gigaPoPs Abilene Network
