    7373Above figure shows the architecture of the CRON,  which consists of two main components: (i) hardware (H/W) components, including a 10Gbps switch, a 1Gbps switch, optical fibers, network emulators, and workstations; and (ii) software (S/W) components, creating an automatic configuration server that will integrate all the H/W components to create virtual networking and computing environments based on the users' requirements. All components are connected at two different networking planes: a control plane connected with 100/1000 Mbps Ethernet links and a data plane connected with 10 Gbps optical links. To allow access from outside networks, such as Internet2, NLR, and LONI, and to connect to external compute resources, the switch at the data plane has four external 10 Gbps optical connections that will extend the capacity of CRON and integrate it with existing networks and projects for the purpose of cooperative scenarios shown in the Figure
