The aim of this article is to present an original modeling of dynamic
load balancing, using queueing theory and probabilities. After briefly
presenting the dynamic load balancing techniques, we model the optima
l strategy. We verify the analytical results by using simulation techn
iques. This modeling method is applicable to other strategies, incorpo
rating a greater number of variables. The analysis of the results obta
ined by the optimal model allows us to progress to the elaboration of
other strategies to improve load balancing efficiency.
