A CAD system for distributed networks design

This paper presents an interactive computer package which aids the distributed network designers in choosing the optimum capacity for different links. This package gives the designer a tool to experiment different assignment strategies and compare their results. Four assignment strategies are implemented in this package: Minimum Average Time delay, Min-Max, Equal Capacities and Proportional Capacities Assignment strategies. The designer can also use it to investigate the effect of different routing policies on the values of optimum capacity. Reliability of the network can be examined by choosing routes which avoid broken links. The package is designed to be flexible and extendable so any module can be replaced or new modules can be added without change in other modules of the package.
