Initializing of a system arrangement for the packet-based transfer of data

A method for initialising a system arrangement for the packet-based transmission of data on up to 128 virtual data paths via a physical data channel of an automobile with deterministic latency, comprising:

• a readout (100) of a provided latency time specification or a bandwidth specification of the data channel for all virtual data paths for the transmission of a bit sequence to be transmitted;
• a setting (102) of a packet length for each of the 128 data paths, taking into account a plurality of potential predefined packet lengths of the bit sequence, wherein the plurality comprises fewer potential predefined packet lengths than the number of data paths, the packet length being selected (101) from the plurality of potential predefined packet lengths in each case in such a way that short packet lengths are used for short latency requirements and low available bandwidth and long packet lengths are selected for long latency requirements and high available bandwidth, the data to be transmitted being n*112 bits+187 bits, where n is a natural number,
• wherein the physical data channel is implemented as a physical cable or line.
