This method consists in making a routing automaton (50) carry out verifications on the integrity of the packets arriving at the packet switch (1), their periods of stay in the packet switch (1), their matching with the virtual paths that they claim to take as well as the routings proper, within the packet switch (1), of the datagrams that have satisfactorily undergone the verification. The routing automaton (50) is provided with a random access memory of instructed values (60) containing a table of virtual path local descriptors. The processing time of the automaton is divided into a repetitive sequence of time slots individually allocated to the different input ports (21, 22, 23) of the packet switch (1). |
