Economic analysis of integrated voice and data networks: A case study

摘要: This paper describes the results of a study to evaluate alternative switching strategies for future integrated voice and data networks. Three fundamental problems are addressed: 1) economics integrating applicatiom in common communications system; 2) comparison technologies networks; 3) cost-effectiveness digitization rates strategies. broad variations thereof investigated compared. The are: circuit switching, packet hybrid (circuit-packet) switching. Each technology can accommodate either or applications separately combined requirements an fashion. Results studies regarding systems option provided sensitivity tested with respect traffic variations, cost trends transmission, network performance variables. significant variables which affect identified quantified. intent this is identify quantify demonstrate long-term low operating costs, necessary effort provide basis determining most cost-effective evolutionary path communication systems. It recognized that transition associated costs may be other important factors ultimate path. However, these was not objective study. Neverthless, provides framework target detailed evolution, planning, analysis.
