Abstract: A method, arrangement, computer program and computer program product for improving communication between devices of an industrial automation system running automation applications as well as to such an industrial automation system. The devices include a first and a second endpoint device of a communication path for a data stream through a time sensitive network and for which a corresponding application has an application cycle time at which the first and second endpoint device are to transmit data to each other. The first endpoint device detects a communication degradation of the data stream, which communication degradation is indicative of congestion and performs a congestion limiting activity from a group of congestion limiting activities, which group at least includes an activity of increasing the application cycle time of the data stream.
