ABSTRACT:
The invention relates to a method of routing data blocks in a data communication network comprising a plurality of nodes through which the data blocks are routed. A node identifier and a port identifier are assigned to each node and to each port in the nodes, respectively. Once the route has been established in the sending station, thereby identifying the nodes in the route to be crossed over by the data blocks and in each node of the route the destination port to be used by that node, the sending station includes in the data blocks to be sent a routing tag RT whose value is such that:
