System and data transmission PROCESS

The invention relates to a method and a system implementing a relay mechanism by all nodes, all connected networks and subnets and routing defined by the Directive: • Upon receipt of a cell number "n" different index, irrespective of the transmitter to reconstruct the message. • Until, on each of the networks, a predefined number of different index of cells was made or received. The relay is in particular to decode the received message and the recoding of a sequence of single fountain code to each transmission of the same message whatever the relay node.
