A network, such as a network on chip, includes a plurality of levels of switches organized in a hierarchy. The connections between the switches are constituted by connections which are able to transport packets of information in opposite directions in such a way that one switch, or one process associated thereto, can send or receive packets in the framework of the network along one and the same path, constituted by an ascending stretch, in which the packet goes up the network hierarchy as far as a root switch common to the source and to the destination, and a descending stretch in which the packet goes down the network hierarchy towards the destination. A routing logic is provided, configured for defining the routing path in a non-adaptive way, selecting the ascending stretch according to the source and the descending stretch according to the destination, irrespective of the traffic of the packets.
