the Performance of the File Mover

The File Mover [6] 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 part the potential benefits typical of overlay networks. In this paper 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 have been compared with those attained by
its standard version.
1 Introduction
A rather large set of scientific disciplines, such as High-Energy Physics, Climate Modeling, and Life Sciences, requires
the archival, retrieval, and analysis of massive data collections, whose size may well be in the order of tens to hun-
dreds of Megabytes (and sometimes even Petabytes) [18]. Data Grids [28], providing infrastructure and services for
distributed data-intensive applications, are at the moment regarded as the best solution to the processing needs arising
in the above application domains. As observed in [9], one of the crucial components of Data Grids is its file transfer
infrastructure, that must be conceived in such a way to reduce as much as possible the time taken to transfer a file
