Abstract
The invention relates to a method, in particular a time controlled error-tolerant method, for periodically transporting real-time data in a computer system, in particular in a distributed computer system, said computer system comprising node computers (-), in particular a plurality of node computers (-), and distributor units (), in particular a plurality of distributor units (). The node computers and the distributor units have access to a global time, and real-time data is transported by means of messages, preferably by means of time-controlled real-time messages. The topology of the computer system corresponds to an intree, and node computers (-), are arranged on the leaves of the intree. One or more sensors (-) is assigned to each node computer (-), and the node computers (-) arranged on the leaves of the intree transmit sensor data in the payload of messages in the direction of a control center () located at the root of the intree at points in time, preferably at synchronized points in time. The payload of one or more incoming messages in a distributor unit is transported out of the distributor unit with an outgoing message, and an individual time plan is generated a priori for each distributor unit, wherein the time plan contains a periodically repeating starting time () for transmitting a message () going out of the respective distributor unit, said starting time being calculated a priori from—the a priori known time of arrival of a controlling payload to be transported, which is specified a priori for example, of one of the incoming messages, in particular a time-critical payload to be transported of one of the incoming messages, —minus the a priori known lead-time interval ([]) of the outgoing message (), —plus at least one time interval ()] required to copy a data element of the controlling payload, in particular the time-critical payload of the incoming message (), into a data element of the payload of the outgoing message (); and the payloads of the incoming messages are copied into the payload of the outgoing message by carrying out the a priori generated time plan.
