This transmission network for transmitting information, of the type comprising at least two associated loops (2, 3) for transmitting information, in each of which functional nodes (4, 5) are integrated, each comprising at least one distribution module for distributing messages (6, 7) between the input and output ports of the node and at least one network interface module (8, 9) associated with this distribution module, is characterized in that the network interface modules (8, 9) of at least certain of the nodes of at least one of the loops (2, 3) are connected to the distribution modules (6, 7) for distributing the nodes of at least one other loop.
