An approach to evaluating computer network simulation tool support for verification and validation

Domain-specific tools are frequently used in modeling and simulation (M&S) of computer networks. While such tools are important to varying degrees across different stages of the modeling and simulation lifecycle, they can also impose major constraints on the expressivity of models, and limit the ability to carry out model verification and validation (V&V). An approach is devised for evaluating domain-specific M&S tools, in which one analyzes the model development process for each tool, and identifies key advantages and limitations that affect different aspects of development, particularly the ability to perform V&V. One then chooses a set of features based on one’s requirements, which broadly capture the observed characteristics of the selected tools. After assigning a quantitative or qualitative rating to each tool with respect to each feature, one can assess the effectiveness of each tool for use in a given M&S project, based on the assigned ratings, and the importance of each feature to the project in question
