The U.S. Navy is moving away from its current stovepiped network system toward one that is service-based and in line with the concept of an open architecture. This report investigates the potential software services within the Program Executive Office, Command, Control, Communications, Computers, and Intelligence that could be used as part of a service-oriented architecture.

The Navy is increasingly dependent on networks and associated net-centric operations to conduct military missions, so a vital goal is to establish and maintain dependable networks for ship and multiship networks. The authors develop a framework for measuring the dependability of naval networks and describe a software tool for modeling the impact that individual network components have on overall mission operational availability.
