Abstract: A method for establishing time-sensitive communication from at least one end device in an industrial plant into an Ethernet network with extended functionality for time-sensitive communication includes obtaining a first information model of the at least one end device, obtaining a second information model of the Ethernet network; determining first configuration information; determining second configuration information; transmitting the first configuration information to the at least one end device; and transmitting the second configuration information to the at least one network device.

Abstract: A method for operating a time-sensitive network, TSN, having a first, high-importance segment and a second, low-importance segment, includes remapping, using TSN per-port priority regeneration, priority labels attached to data streams received on the first port and the second port to updated priority labels; splitting the data streams into a “preempting” class and a “preemptable” class based on a mapping from updated priority labels to classes; and forwarding the data streams from a border network element to at least one next-hop network element. When congestion is present on a link to the next-hop network element, the forwarding of “preempting” data streams takes precedence over the forwarding of “preemptable” data streams.
