Abstract

In a data driven information processing system including processors which processes datapackets, a method of verifying identification information allocated to the processors includes the following steps: previously specifying a path for a datapacket via the processors; providing the data driven information processing system with information specifying the number of the other processors for the datapacket to pass through until the packet reaches a certain processor from the input of the system in the path, and a datapacket for identification which stores an identification data verification instruction; a first transmission step of transmitting the datapacket for identification to the processor along the specified path while updating information indicating the number of processors and applying the packet to the processor; a step of producing a result datapacket which stores the identification data of the processor for output in the specified path; a second transmission step of transmitting the result datapacket along the specified path for output; and a step of verifying identification data stored in the output result datapacket.
