A Graphical User Interface Design for Network Simulation

Computer Operations Performance System (COPS) is a simulation tool for network modeling. COPS consists of five interactive components: the command interpreter, the graphical user interface, the library, the simulation engine, and the output analysis. The organization of COPS is illustrated in Figure 1. The user constructs models by using the graphical user interface (GUI). The command interpreter interacts with the GUI and the model library to construct the executable code for the simulated model. The simulated model is then executed by the simulation engine. The results are displayed by the output analysis component.
