In this paper we present the key elements of the NICCI (Network-centric Infrastructure for Command, Control and Intelligence) infrastructure and compare and contrast them with similar capabilities provided by the OGSA (Open Grid Services Architecture) grid infrastructure. We also examine the advantages and disadvantages of using the OGSA grid infrastructure as a substrate for implementing NICCI and highlight some of the technology gaps. Finally, looking ahead at the future of the grid computing research, we identify several research thrusts where we believe there is a natural synergy and opportunity for cross-pollination between the NICCI-sponsored research and the ongoing efforts of the grid community.

Approaches and metrics useful in assuring reliable software, starting from the time at which requirements are defined, are discussed. This study provides the background for a discussion of technology and policy advances that are expected to greatly improve the ability to field the systems promised. >
