A method for the routing of a packet of data in a digital transmission network where each packet is formed by a header, enabling this packet to be identified and guided, and a part containing information elements to be conveyed. This method consists, at each node of the network, of a first step for extracting, from the header, the address of a word of a memory containing the information elements needed to identify the header and to guide the data elements conveyed by the packet coming into the node and a second step for creating, according to the header of the incoming packet and the information elements contained in the word of the memory, a new address designating a memory zone containing at least one new header and the information on the outgoing direction of the packet or packets coming out of the node. The method can be applied to digital transmission networks where it is necessary to identify and route packets of data.
