This paper focuses on bus communication networks where every terminal is modeled as a multi-states component with a propagating failure state. An analytic expression of the reliability of the transmission between two terminals is first computed. From that, it is shown that partitioning the bus may lead to increase, decrease or let unchanged this reliability, according to the positions of the considered terminals in the different partitions. This analysis is aiming at providing an efficient help for the designers of communication networks of critical systems.
