     38CRON is the project funded by NSF MRI (Major Research Instrumentation) program, which builds a virtual high speed optical networking and computing testbed. The CRON testbed can provide up to four 10Gbps optical hardware emulated paths, four 5Gbps optical software emulated paths, and 16 high-end workstations attached to those paths simultaneously. A large number of application developers and networking researchers can share those virtually created high speed networking and computing environments without technical knowledge of networks and communications and without interference of other users. This virtual feature of CRON is exactly matched to the concept of GENI - Virtualization and Other Forms of Resource Sharing.

     40The cyberinfrastructure, CRON, provides integrated and automated access to a wide range of high speed networking configurations. Figure 1 shows how CRON can be reconfigured to emulate such optical networks as NLR (National Lambda Rail), Internet2, LONI (Louisiana Optical Network Initiative) configuration, or purely user-defined networks having different networking characteristics such as bandwidth, latency, and data loss rates. Moreover, users can dynamically reconfigure whole computing resources, such as operating system, middleware, applications, based on their specific demands. Due to the automated and reconfigurable characteristics, all types of experiments over CRON will be repeatable and controllable. This reconfigurable feature of CRON coincides with that of GENI – Programmability
