PURPOSE:To attain efficiently circulation of information by providing additionally a discriminating section detecting a circulation signal and a function selecting an address to be the shortest path to a communication control processing function section to allow the circulation signal to select the address of the shortest path thereby performing communication processing. CONSTITUTION:In circulating a certain kind of information from a CPU1-1 to CPU1-2-1-4, a SEND ANY signal and a list of CPUs to be circulated are added. A communication control processing device 2-1 receives this signal at the discriminating section 21, which discriminates that the signal is the SEND ANY signal, the section 21 actuates a selection section 22 to retrieve a communication state table 23. CPU names representing the system constitution and the communication state of each device are stored in the table 23. The selection section 23 uses the information of the table 23, selects, e.g., the CPU1-3 having the shortest communication time, actuates the communication processing section 24 to transfer the information to the CPU1-3. The operation above is repeated. |
