A method and a system are provided implementing a mechanism for relaying by all the nodes, on all the networks and sub-networks connected and defined by the routing directive: as soon as a number of cells 'n' of different index have been received, whatever the sender thereof, making it possible to reconstruct the message and until, on each of the sub-networks, a predefined number of cells of different index has been sent or received. The relaying comprises decoding the message received and recoding it by a sequence of the unique fountain code on each sending of the same message whatever the relay node.

System and method for transmitting data

In a method of enhanced reliability routing within a system including one or more networks having several nodes connected together by communication means, the system using a link-state routing protocol constructing the topology of the nodes within a system of nodes, the routing method determines the logical topology of network interconnection nodes NIN by using modules which perform the following: discovery of the neighborhood by functions of the physical networks; smoothing of the information provided by TNAs to improve the stability of the protocol; distributing the neighborhoods to the set of NINs; relaying of the information associated with a node by a subset of the NIN node; hop by hop enhancement of the reliability of the transmission between various nodes; transmission in point-to-multipoint mode; announcement of oriented characteristics of logical links solely by the source routers of the links; marking of the signaling data so as to manage non-sequencing in reception; and calculation of the global topology.
