Abstract: The invention relates to a communications network comprising a large number of nodes (1, 2, . . . , 7), at least two (1, 7) of which are connected via at least two different routes (1-2-3, 3-4, 4-7; 1-2-3, 3-5, 5-6, 6-7). At least one of said routes comprises a radio link (3-4), which runs from a transmitter to a receiver. The transmitter and the receiver support a large number of transmission modes with varying robustness and data throughputs and comprise elements (17) for defining the transmission mode used depending on the detected transmission quality of the radio link (3-4, . . . ). The communications network is also equipped with elements for distributing (15, 18) the data traffic that is to be transmitted from one of the two nodes (1) to the other (7) between the two routes (1-2-3, 3-4, 4-7; 1-2-3, 3-5, 5-6, 6-7), according to their data throughput.
