Interactive graphics and menus for computer network models

摘要

The Hierarchical Modeling System (HMS) is a single software package that provides a discrete event simulation and analytic modeling capability for computer networks. The analyst may reconfigure the network model depending on the number of nodes and their interconnections by making a few changes to some simple data files-no recoding of the model is necessary. This paper describes an interactive graphics front end for HMS which allows the analyst the capability for reconfiguring the model at a graphics terminal. This provides a faster, less error prone input method. In addition, changes in the network topology are more readily understood when presented graphically. Menus are used with the graphics input in order to make changes to nodal specific models.
