NATIONAL IVHS ARCHITECTURE DEVELOPMENT STRATEGY

Abstract

National information and control systems are emerging that require system architectures for deployment across the nation, e.g., air traffic control systems, military command and control systems, and other national information systems. The required characteristics for the national level architectures include modularity, openness, and evolvability. Modularity permits a variety of system configurations. Each may be designed to size a community's system with a level of functionality commensurate with the community's needs. Openness enables system interoperability with other systems at both horizontal and vertical levels. Evolvability requires the system to permit functionality and scope changes as the community and technology evolves. Achieving these characteristics necessitates a formal strategy for developing architectures, for information and control systems, at the national level. A national level, information and control system is a system that is made up of systems, e.g., a supersystem. Developing an ar...
