This combination allows user-initiated ad hoc dedicated allocation of network bandwidth for high-demand, real-time applications and network services, delivered over an optical fiber infrastructure.
[2] The experimental Internet2 HOPI infrastructure, decommissioned in 2007, was a forerunner to the current SONET-based Ciena Network underlying the Internet2 DCN.
The Internet2 DCN began operation in late 2007 as part of the larger Internet2 network.
[3] It provides advanced networking capabilities and resources to the scientific and research communities, such as the Large Hadron Collider (LHC) project.
[4] The Internet2 DCN is based on open-source, standards-based software, the Inter-domain Controller (IDC) protocol, developed in cooperation with ESnet[5] and GÉANT2.
