Editing Abilene Network (section)

==2006/2007 Upgrade==
The Abilene project had used [[optical fiber]] networks donated by [[Qwest|Qwest Communications]]. In March 2006, Internet2 announced its upgrade plans and migration to [[Level 3 Communications]]. Internet2's Abilene transport agreement with Qwest expired in October 2007. Unlike the previous architecture, Level 3 manages and operated an [[Infinera]] Networks based [[DWDM]] system devoted to Internet2. Internet2 has control over provisioning and uses the 40 wavelength capacity to provide IP backbone connectivity as well as transport for a new SONET-based dynamic provisioning network based on the [[Ciena Corporation]] CoreDirector platform. The IP network was based on the [[Juniper Networks]] T640 routing platform.<ref>{{cite web |title= Internet2 Network Upgrade |work= Blog |author= Chris Robb |date= October 9, 2007 |url= http://i2net.blogspot.com/ |accessdate= September 16, 2011 }}</ref>

When the transition to the new Level3-based infrastructure was complete, the name ''Abilene'' ceased to be used in favor of ''The Internet2 Network''.
