Exploiting Overlay Networks Features to Enhance the Performance of the File Mover

The File Mover is a file transfer infrastructure, based on the overlay networks paradigm, specifically conceived to provide high-performance file transfers for Data Grids. In its current implementation, the File Mover exploits only in pan the potential benefits typical of overlay networks. In this chapter we consider three possible extensions of the File Mover, aimed at increasing its performance, that better exploit the characteristics of overlay networks. The performance improvements obtained with these extensions are demonstrated by means of a set of experiments, in which the performance obtained by an extended version of the File Mover has been compared with that attained by its standard version.
