1. A method for communication between nodes of a network interconnected by a transmission channel and wherein each node is identified by a node identification number, the method comprising:
- (a) at least one transmitter node emitting at least one message to at least one message recipient node wherein the transmitter node originates the message and the message recipient node represents a final destination for the message;
(b) said message when originated and emitted by the transmitter code comprising a description of a path between said transmitter node and said message recipient node, said path being defined by the transmitter node that originates and emits the message, via a sequence of node identification numbers along said path;
(c) the nodes of the path regenerate the message by sending it to the next node defined by said path stored in the message;
(d) each node that receives a message from a node preceding it along said path sends a confirmation of reception of the message to said node preceding it;
(e) when a node does not receive a message of confirmation to its own message addressed to the subsequent node along the path, it makes at least one attempt at transmission of said message to the node which, in said path, is subsequent to the node from which the confirmation message has not been received;
(f) wherein each of said messages comprises an identification number of each subsequent node along said path to which the message must be transmitted, said identification of the subsequent node identifying to which node of the path defined in the message said message must be transmitted;
(g) when a message recipient node receives said message, it generates a reply message to the node that emitted the message and containing a description of the path from the node that receives the message to the node that has emitted the message received;
(h) when a node different from the message recipient node receives a message with a subsequent node identification number different from its own identification number, said node remains inert; and
(i) when a node receives a message in which the identification number of the subsequent node corresponds to its own identification number, it generates an echo of the message, replacing the subsequent node identification number with the identification number of the following node in the sequence of node identification numbers defining said complete message path in said message; and
wherein said messages comprise control message of all the nodes along the path between a node emitting the message and the message recipient node, said control messages being modified by each node along the path, with the addition of at least one datum relating to a condition of each node along said path, and wherein the said datum added by each node to said control message is stored and delivered to the message recipient node.

Abstract
A method for communication between nodes (UR1; UR2; UC1-UC16) of a network, interconnected by a transmission channel and each identified by a node identification number in which at least one transmitter node emits at least one message to at least one message recipient node. The message comprises a description of a path (PH) between the transmitter node which emits the message and the message recipient node. The path is defined by the node that emits the message via a sequence of node identification numbers along the path itself.

dividing said control nodes into a plurality of groups, each group comprising a series of control nodes, each group being assigned to a collecting node and the collecting node interrogating via said messages the control node to collect information from said control nodes; andwherein each control node of a group is also assigned to an additional collecting node and wherein in the absence of faults on the collecting node, the control node of each group communicate with the respective main collecting node to which they are assigned; and
in the event of a fault on said main collecting node, the control node assigned to it are re-assigned each to the respective additional collecting nodes. - View Dependent Claims (3, 4, 5, 6, 7, 8)
