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: 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.
