Architectural considerations for accessing the post-1995 CONUS DCS/DSN: target MILDEP local information transfer networks

After establishing the need for using a functional architecture design paradigm, the author explicitly considers target MILDEP (military department) local information-transfer architectures as an important input for the design of post-1995 CONUS DCS/DSN (Defense Communications Agency/Defense Switched Network) access architectures. A synopsis of the target MILDEP local information systems indicates that the common denominator is ISDN. Representative base communication architectures are used to illustrate this, although they do not indicate the extent to which individual mission needs might force a departure from the target architectures. Access to the common user long-haul network (both private and public) is a relatively unexplored but critical area. A functional architecture approach appears necessary in order to define, standardize, and implement advanced DCS/DSN services and to develop a viable network evolution study
