A design model for teleprocessing systems

Abstract

The model, in the form of a computer program and associated data bases, is capable of determining the cost of a teleprocessing system designed to meet specified load requirements. In the current version, the system may serve up to 120 cities, of which to 20 may be outside of the continental United States. Central switching and data processing may be provided in up to 20 computing centers located at arbitrarily chosen cities of the system. The model terminal equipment to be deployed in each city central-station equipment for each computing center. Data communication is provided optionally by means of leased circuits configured in either ring or tree networks, direct-distance-dialing services, WATS-like services, o r packet-switched services. The model is suitable for exploration of system costs design features as functions of deployment, center locations, types and amounts of work processed common-carrier tariffs, redundancy requirements, and other variables.
