Descriptive Data Analysis of File Transfer Data

There are millions of files and multi-terabytes of data transferred to and from the University of Tennessee's National Institute for Computational Sciences each month. New capabilities available with GridFTP version 5.2.2 include additional transfer log information previously unavailable in prior versions implemented within XSEDE. The transfer log data now available includes identification of source and destination endpoints which unlocks a wealth of information that can be used to detail GridFTP activities across the Internet. This information can be used for a wide variety of reports of interest to individual XSEDE Service Providers and to XSEDE Operations. In this paper, we discuss the new capabilities available for transfer logs in GridFTP 5.2.2, our initial attempt to organize, analyze, and report on this file transfer data for NICS, and its applicability to XSEDE Service Providers. Analysis of this new information can provide insight into effective and efficient utilization of GridFTP resources including identification of potential areas of GridFTP file transfer improvement (e.g., network and server tuning) and potential predictive analysis to improve efficiency.
