Time-triggered cut through method for data transmission in distributed real-time systems

A distributed real-time computer system for the periodic transport of real-time data, wherein the distributed real-time computer system comprises:

• a plurality of node machines (100, 101, 102, 103);
• and
• a plurality of distributor units (121, 122),wherein the plurality of node machines (100, 101, 102, 103) and the plurality of distributor units (121, 122) comprise hardware configured to have access to a global time, and wherein the real-time data is configured to be transported by time-triggered real-time messages, wherein the time-triggered real-time messages are configured to be transported in the plurality of distributor units in periodic time slots,
• wherein attributes of the time-triggered real-time messages are configured to be assigned a priori to the periodic time slots of a distributor unit (121, 122) of the plurality of distributor units, wherein the time-triggered real-time messages are configured to be transported through the distributor unit (121, 122) from the periodic time slots, and stored in the distributor unit (121, 122), and wherein the attributes assigned to a periodic time slot of the periodic time slots indicate the output port or the output ports of the distributor unit (121, 122), to which a time-triggered real-time message arriving in the periodic time slot in the distributor unit (121, 122) is forwarded in the distributor unit (121, 122), and
• immediately after the beginning of the arrival of the time-triggered real-time message in the distributor unit (121,122) and immediately after the arrival of a start of a header of the arriving time-triggered real-time message, the time-triggered real-time message arriving in the periodic time slot in the distributor unit is configured to be forwarded to the output port or to the output ports of the distributor unit (121, 122), which are specified in the attributes assigned to the periodic time slot.
