Simulation via implementation with applications in computer communication

The traditional approach to performing discrete digital simulation has been one of developing a mathematical or statistical model to represent a process, programming this model on a large scale computer, and then executing the model to obtain performance results. In this study, the authors have developed a simulation of a computer communication network by simulating the users in a central computer and implementing the remainder of the network in actual network processors. This allows for authentic measurements on physical computers and reduces costs since one buys reusable computers instead of buying computer time.
