Publication number: 20240129247Abstract: A method for operating a time-sensitive network (TSN) includes splitting data stream on network elements into a “preempting” class and a “preemptable” class based on a mapping from priority labels; forwarding the data streams to respective next-hop network elements, wherein the forwarding of “preempting” data streams takes precedence over the forwarding of “preemptable” data streams; and forwarding the data streams received from both segments based on the priority labels and the classes of the data streams to at least one next-hop network element; wherein forwarding of “preempting” data streams takes precedence over forwarding of “preemptable” data streams; wherein the priority label attached to the data stream that has the highest priority is different from the priority label attached to the data stream that has the highest priority within the second segment.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Applicant: ABB Schweiz AGInventors: Alexander Gogolev, Johan Akerberg, Roland Braun

Patent number: 11929936Abstract: 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.Type: GrantFiled: February 16, 2021Date of Patent: March 12, 2024Assignee: ABB Schweiz AGInventors: Alexander Gogolev, Marius-Petru Stanica, Thomas Gamer

Publication number: 20220417160Abstract: 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.Type: ApplicationFiled: June 27, 2022Publication date: December 29, 2022Applicant: ABB Schweiz AGInventors: Alexander Gogolev, Marius-Petru Stanica, Hariram Satheesh
