Abstract: A method for transmitting a first data packet from a receiving input-buffer to a receiving output-buffer, the first data packet in the receiving input-buffer having a non-TSN format and the first data packet in the receiving output-buffer being TSN-compliant, includes the steps of: analysing the first data packet, which has been retrieved from a non-TSN device, in the receiving input-buffer; adding a first data packet time to the first data packet according to a Precision Time Protocol (PTP); adding a predefined first data packet priority level to the first data packet according to a Priority Code Point (PCP) of an 802.1Q tag; transmitting the first data packet to the receiving output-buffer; and sending the first data packet according to the first data packet priority level to a TSN-compliant 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.

Abstract: Supervision of industrial plants can be improved by comparison and analysis of process information and network information. The comparison may be used to provide alarms and operator information for network-related or process device failures. The information may also be used to identify a cause of a failure. A method is described for supervising an industrial control system, including a plant network for supervision, a client/server network for server connection with workstations, and a control network connected to industrial controllers. The method comprises the steps of gathering process information, and gathering network information, and by comparing information provided by data communications network monitoring with process control information and using the result of the comparison to assist in determining a cause of a problem or possible problem in a process controlled of the industrial control system.
