Resumen:
SimuLIHM is a simulator built with virtual reality features for training purposes. It
recreates the operating environment of a substation of an electric system and it was
designed to support individual and team training using a distributed network
environment, which event-driven architecture aims to reduce the demand on network
resources. This work aims to determine the boundary conditions of using this system
from the point of view of the load applied to network and the quality of service
perceived by its users. The study presented in this paper concerns assessing the
network requirements for a typical use case of SimuLIHM, that involves a tutor and
two operators, and to determine the maximum number of simultaneous client machines
that can connect to its training environment. To accomplish that, we applied several
tests supported by tools for the injection of controlled traffic on the network, allowing
us to analyze the effect of the increasing network load on the performance of the
simulator. It is noteworthy that the experiments’ results failed to prove the relationship
between the human error rate and an increased network load, thus requiring further
investigation. However, the experiments confirmed this work hypothesis concerning the
impact caused by the use of the simulator on the network traffic which proved to be
negligible, allowing the parallel connection of dozens of clients to a single instance of
the simulator, even on low-speed networks.
