Dynamic circuit network
A dynamic circuit network (DCN) is an advanced computer networking technology that combines traditional packet-switching communication based on the Internet Protocol, as used in the Internet, with circuit-switching methodologies that are characteristic of traditional telephone network systems. 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.
Implementation
Dynamic circuit networks were pioneered by the Internet2 advanced networking consortium. [1] 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.[2] It provides advanced networking capabilities and resources to the scientific and research communities, such as the Large Hadron Collider (LHC) project.[3]
The Internet2 DCN is based on open-source, standards-based software, the Interdomain Control (IDC) protocol, developed in cooperation with ESnet and GÉANT2.[2] The entire software set is known as the Dynamic Circuit Network Software Suite (DCN SS).
