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.

14. A communications network, comprising:
-
a) a plurality of nodes, at least two of the nodes being connected via at least two different routes, at least one of the nodes including a radio link running from a transmitter to a receiver, the transmitter and the receiver supporting a plurality of transmission modes with different robustness and data rates;
b) means for establishing an employed transmission mode as a function of a recorded transmission quality of the radio link; and
c) means for distributing data traffic from one of the at least two nodes to the other of the at least two nodes on the at least two routes corresponding to their data rate. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of transmitting a data stream between two nodes of a communications network which are connected via at least two different routes, at least one of the nodes including a radio link running from a transmitter to a receiver, comprising the steps of:
-
a) recording transmission quality of the radio link;
b) establishing a transmission mode for the radio link by means of the recorded quality; and
c) transmitting the data stream on the radio link on one of the routes if a rate of the data stream does not exceed a transmission rate of an established mode and, if the transmission rate of the established mode exceeds the rate of the data stream, relocating part of the data stream on another of the routes. - View Dependent Claims (21, 22, 23, 24, 25, 26)
