TY - JOUR TI - Trade-offs of secure processing in centralized versus distributed networks AU - Lientz, Bennet P. AU - Weiss, Ira R. T2 - Computer Networks AB - Simulation was performed for specific network configurations to assess the effect of imposing security measures on a portion of the workload. The results provide a methodology for performing trade off analysis. The trade-offs are presented in terms of the measures of response time, workload, and cost. Network types included distributed, semicentralized, and centralized configurations. The analysis was conducted using a simulation model which is briefly summarized. The results of the simulation for the cases considered indicate that economies of scale shift from centralized to semicentralized configurations for a fixed I/O bound workload. This occurs when throughput degrades, due to the imposition of security measures, approximately 15% (10%) when 10% (20%) of the workload requires secure processing. Degradation is also examined when certain centers process only secure workload versus distributing both secure and non-secure jobs across the network.
