Naval communications processing and routing system (NAVCOMPARS): a model for broadcast performance analysis
navalcommunicati00geor.pdf (3.837Mb)Abstract
This thesis represents an analysis of the performance of the Naval Telecommunications System's (NTS) multichannel broadcast. It highlights the speed differential between the Naval Communications Processing and Routing Systems's (NACOMPARS) processing subsystems and the multichannel broadcast's transmission lines. In this effort, the message flow through the NAVCOMPARS is described. An analytic approach was chosen and input statistics, such as average message length and input rates, were gathered for queuing analysis. The operational characteristic upon which broadcast performance is evaluated is the average time delay in the system. The broadcast channel's ability to satisfy future communications requirements is also examined. The analysis demonstrates that, unless the increasing trends in message input rates are reversed or message lengths reduced, a dedicated broadcast overload channel would be required to meet communications requirements throughout the 1980's.
