The Basic Research Simulator, or BARESIM, is being developed at the Delft University of Technology by a consortium between the faculties of aerospace engineering, mechanical engineering, and electrical engineering. The key design goals of the simulator are a state-of-the-art motion base and an overall low-latency response to pilot inputs. A simulator with these properties can be used effectively to investigate certain issues related to vehicle simulation. There are three specific areas of interest: -The dynamic behaviour and control of motion platforms -The performance of vehicle simulations in a ground-based environment -The human factors of vehicle operation The design goals of the simulator have a twofold implication for the communication between the system that make up the simulator. First, the communication must offer sufficient bandwidth and fast enough response times to do low-latency, real-time communication and, secondly, the weight of the cabling used for inter-system communication must be low to avoid influences on the motion base dynamic properties. This report will treat the design of a computer network to interconnect the BARESIM computer systems that meets these demands.
