1. Method for distributing a data-traffic load on a communication network (KN1) with an extensive range of network nodes (NK1 . . . NK4, ZNK) connected via link lines (L1 . . . L6), where;

  • a) a data-traffic-monitoring system (ZNK) ascertains a current data-transfer-loading value (A1 . . . A4) for the respective link line (L1 . . . L6) and/or the respective network node (NK1 . . . NK4, ZNK);

    b) based on the data-transfer-loading values (A1 . . . A4) that have been ascertained, the data-traffic-monitoring system (ZNK) ascertains distribution information (V1 . . . V4) for the respective network node (NK1 . . . NK4) and sends it to the node concerned;

    c) based on the distribution information (V1 . . . V4) that has been received, this network node (NK1 . . . NK4) generates a allocation model, which is used to divide the address information (QA) of data packets (DP) into separate address classes (0 . . . 7), each of which is assigned to one of a number of alternative routes (LW1, LW2, LW3) leading to a particular destination network node (NK4);

    d) when this network node (NK1 . . . NK4) receives a data packet (DP) addressed to this destination network node (NK4), it ascertains the address class (0 . . . 7) from its address information (QA) and sends the data packet (DP) via the route (LW1, LW2, LW3) assigned to the address class (0 . . . 7) that has been ascertained.
