Establishing Dedicated Circuit Between ORNL and MCNC for High-Throughput File Transfers

This document outlines the use of the circuit requestor to set up a dedicated circuit connecting Oak Ridge National Laboratory (ORNL) and the North Carolina Research and Education Network (MCNC). It includes adjustments to kernel parameters for optimized high-throughput connections, the execution of VSFTP for efficient file transfer, and presents experimental results from a demo conducted by Mark McGinley on August 23, 2006. Results featured a ~1GB transfer with a round trip time (RTT) of 17ms and a standard deviation of 0.7 Mbps.
