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.

Navy analysts are struggling to keep pace with the growing flood of data collected by intelligence, surveillance, and reconnaissance sensors. This challenge is sure to intensify as the Navy continues to field new and additional sensors. The authors explore options for solving the Navy s big data challenge, considering changes across four dimensions: people, tools and technology, data and data architectures, and demand and demand management."

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.
