As military command and control (C2) applications evolve and become immersed within an growing net-centric operational environment, the complexity of interactions among component C2 enterprise capabilities will rapidly increase. The adoption of a Service Oriented Architecture (SOA) approach to C2 development, coupled with the incremental fielding of Internet Protocol (IP) based Global Informati...
