COMNET III: object-oriented network performance prediction

COMNET III predicts the performance of communication networks using object-oriented simulation analysis. No programming is required to use the standard, off-the-shelf model and libraries. For situations where a model developer wishes to customize or fine-tune some aspect of the standard model, a MODSIM-based object-oriented program development environment is provided for overriding the behavior 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.
