1. 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 has a non Time-Sensitive Network (TSN) format, wherein the non-TSN format is one of: Profinet, EtherCat, Powerlink, Ethernet/IP, TTEthernet, and/or Modbus TCP protocol, and the first data packet in the receiving output-buffer being TSN-compliant, the method comprising 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 802.10 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-com pliant device.
