A general AUTODIN and Automatic Switching Center (ASC) system description is presented to orient the reader. A GPSS model of the Communications Data Processor (CDP) at the ASC was constructed, as a first step toward constructing an overall ASC simulation model. The capabilities and limitations of the simulation are discussed. Several experiments were conducted to ascertain the effects on the CDP message congestion and transit time of varying the volume of traffic passing through the system and the number of tributaries capable of receiving traffic. A COBOL program, which calculates queuing information for the ASC tributaries, is described. The results of the program output are interpreted and uses of the information produced are discussed. Observed problem areas are presented. Conclusions are drawn concerning the performance of the AUTODIN ASC as shown by the simulation and program. Anticipated project applications are described.
