At present, the research on computer network topologies rests mainly on typically unstructured networks such as mesh networks. Our study evaluates the potential use of three structured geometric network infrastructure designs, namely cross polytope (CP), hypercube (HC) and triangular pyramid (TP), based on their network performance. In this paper, we use simulation modelling to analyse structured network geometries and evaluate their network performance by Riverbed Modeler. We compare the simulation results of an unstructured network design with three structured network topologies for both time-independent and time-dependent applications. The simulation results illustrate that the CP and TP topologies have better results than the unstructured network in response time and network delay under a high-load configuration. In addition, it can be shown that the planarised CP structure exhibits superior performance compared to the other three network designs examined. For instance, the end-to-end delay of Voice displays a value of approximately 0.15 seconds during periods of high load. The evaluation conducted in this paper holds vital importance for the configuration of topological networks in the context of constructing network infrastructure.
