ABSTRACT:
The invention relates to the sending, by a sender, of messages, by means of arrowed packages, in a communications network comprising switch nodes. The packet is prepared by the sender so as to travel over a path that successively takes it to all the nodes where there are subscribers for whom the message contained in the packet is intended. Upon arrival in a node of this type, an arrow, followed by instructions and placed just after the arrow which has enabled the packet to reach the node considered, designates a transmission server which, depending on the instructions, performs the local transmission of the message and enables the packet to continue its path. The arrows and the instructions are removed from the packet, in the course of the path, as soon as they have finished serving their purpose.
