Optimizing function distribution in a terminal network

By lowering cost restraints, microprocessors have enabled functions to be implemented on distributed hardware in a terminal network, where such distribution reflects and enables the distribution inherent in the logical design and operation of the network. The degree of distribution in this application is represented by the level of function executed on distributed terminal handlers, versus a single centrally located handler, and by the number of terminals clustered on each distributed handler. A design model is used to illustrate the variation of the optimum point in the tradeoff between central and distributed designs, based on hardware costs as the major variable.
