COMNET III: object-oriented network performance prediction

COMNET III predicts the performance of communication networks using object-oriented simulation analysis. No programming is requires to use the standard package. For situations where a developer wishes to customize or fine-tune some aspects of the standard model, a MODSIM-based object-oriented development environment is provided for overriding the behaviour of COMNET III objects. Model builders can add parameterized objects or their own customized objects to object libraries. COMNET III provides an integrated graphical environment for model creation, execution and analysis that permits interaction with the model while it executes. In addition to modelling the operation of a network and its protocols in satisfying demands for data transport, COMNET III also models the scheduling of applications on end-systems and the use of processing, storage and transport resources during application execution. A COMNET III model may consist of hierarchically-defined subnetworks
