Abstract: A method for time-slotted scheduling of packets in timeslots between N nodes and K>1 access points in an industrial wireless network, performed by a network controller of the industrial wireless network. The method includes determining the time-slotted scheduling by allocating each timeslot to a respective one of the nodes, wherein each timeslot for each node is divided in K sub-slots, one for each access point, such that in sub-slot k of each timeslot, where 1≤k≤K, transmission or reception of a packet is made between access point k and the node to which that timeslot is allocated. The method includes providing information to the access points about the determined time-slotted scheduling.

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.
