The Abilene advanced research and education network has completed its upgrade from 2.5 Gbps to 10 Gbps. New routers were installed across the 13,000 route-mile national backbone, and all but one OC-48c circuit was replaced with an OC-192c circuit. In the process, several router locations were changed, but all remain collocated in Qwest points of presence (PoPs). Indiana University, Juniper Networks and Qwest Communications, provided the equipment and services to successfully implement the network upgrade. http://abilene.internet2.edu/
