1.1
In the year 2004, with the development of grid technologies in both academia
and industry, the Natural Science Foundation Committee of China (NSFC),
which is one of the main funding parties in China, announced its e-Science
Program named Network-based e-Science Environment. As one of the grid-
related research programs, this program is also referred to as the NSFCGrid.
The program started in 2004 and was completed at the end of 2007. The
main goal of this program is to build up a virtual scientii c and experimental
environment to enable wide-area research such as large-scale computing
and distributed data processing. The research projects are organized into
three layers: basic theory and principles, general testbed, and pilot applica-
tions. In contrast to CNGrid and ChinaGrid, NSFGrid pays more attention
to the fundamental research of grid-related technologies.
CROWN is the brief name for China Research and Development environ-
ment Over Wide-area Network [1], one of the main projects in the NSFCGrid
program, which is led by Beihang University (BUAA), with several partners
