Integrated AUTODIN System Architecture Report. Part 2.
Abstract
This report identifies three alternative architectures for the IAS mid-term (1984-1988), and describes the process and rationale for selecting the preferred (Alternative II) architecture. The perferred architecture represents a distributed architecture where services are provided from a common access are element. The major elements of the architecture are the AUTODIN II PSNs, the Inter-Service/Agency (I-S/A) AMPEs and subscriber terminals. This report identifies the roles and relationships of these mid-term IAS elements, identifies the I-S/A AMPE as the replacement for today's AUTODIN I switching centers and the current Service/Agency AMPEs, and recommends an architectural structure which modes switching functions closer to the user. This approach will reduce the dependency on the more vulnerable backbone switches and should enhance overall survivability. Based upon the evaluation criteria of operational effectiveness, flexibility survivability/availability, transition, and cost, the preferred mid-term architecture: (1) satisfies all of the identified services/functions; (2) offers significant cost reduction through standardization; (3) provides improved access reliability; (4) permits improved speed of service; (5) provides flexibility in satisfying user unique requirements; (6) can be implemented in an evolutionary process; and (7) provides the framework for continued development through 1988 and beyond.
